AI Chatbot for Website in 2026: Quick21 + 6 Honest Picks

Most AI chat tools take six weeks to install and answer like a brochure. We ranked the seven that don’t — with sourced pricing, real free-plan terms, and the kind of trade-offs most listicles skip. Researched 2026-05-23, every claim cited at the bottom.

TL;DR — the verdict

1. Quick21 — best overall for SMB websites in 2026. Real free plan with AI included, the bot writes itself in your brand’s voice from your real site, and the welcome message auto-localises into 30+ visitor languages. Start free, no card.

2. Tidio — strongest brand recognition in the SMB live-chat category; Lyro AI is solid but limited on the Free plan to 50 one-off conversations.

3. Intercom Fin — best AI quality if you have budget; $0.99 per resolution on top of $29-$132 per seat per month gets expensive fast.

4. Crisp — clean per-workspace pricing for support teams already in Europe; AI (Hugo) requires a separate decision.

5. Chatbase — best at training a bot from a doc corpus; light on the handoff and team-inbox side.

6. HubSpot Chatbot — fine if you’re already on HubSpot CRM; the free chatbot is rule-based by default.

7. ChatBot.com — flow-builder first, AI second; no perpetual free plan.

What an AI chatbot for your website should actually do in 2026

Before ranking the tools, it’s worth being clear about what a chatbot is supposed to deliver. The category has changed a lot since 2022, and a lot of vendors are still selling 2022-era products with 2026-era marketing.

A modern AI chatbot for a website does four jobs at once. It greets the visitor in their language — not in English-by-default with a translation toggle hidden in a settings menu, but in whatever language your site itself is written in, detected automatically. A French bakery’s visitors should be greeted in French. A Tamil-Nadu storefront’s visitors should be greeted in Tamil. If your bot opens with “Hi, how can I help?” to a Spanish-speaking visitor on a Spanish-language site, you’ve already lost roughly half of them before the conversation has started.

It answers questions from your real website content, not from a template or a generic foundation-model knowledge base. The bot needs to know your service names, your pricing, your hours, your return policy, your shipping zones, your specific industry vocabulary. Not because that’s a nice-to-have, but because every confident-sounding wrong answer the bot gives costs you a customer. Vendors who require you to manually upload knowledge-base articles, paste FAQs into admin forms, or sit through a configuration call before the bot can answer one real question are charging you for the work they aren’t doing themselves.

It knows when to step back. The bot that tries to handle everything is the bot that hallucinates refund policies, makes up product specs, and quotes prices that aren’t in any of your pages. A well-built modern chatbot recognises when it’s out of its depth and hands the conversation to a human — with the full message history, the visitor’s original question, and a note about which of your pages the bot consulted while trying to answer. A “handoff” that just dumps the visitor into a cold inbox is the same as no handoff at all.

It works on the platform you already use, without a custom integration project. If your site is on Shopify, you should be able to install the chatbot by pasting one line into your theme. If you’re on WordPress, a footer snippet. If you’re on Wix, the custom-code block. If you’re on a hand-rolled Next.js or Astro setup, the same one-line script. Vendors who charge you for a Shopify app, a WordPress plugin, and a separate enterprise SDK are charging you three times for what should be one script tag.

Beyond those four core jobs, the things that separate a great chatbot from a passable one in 2026 are: real free-plan terms (not a 14-day trial pretending to be free), pricing that doesn’t punish you for getting more website traffic, brand-voice customisation that takes minutes not hours, and a setup flow that lets you ship the same day you sign up rather than scheduling a kickoff call. Most of the tools on this page do most of these. Quick21 does all of them. That’s the case we’ll make below, with sourced facts for every comparison.

How we evaluated each AI chatbot for websites

Most chatbot listicles are pricing-table plus marketing copy. Buyers actually care about six things, and they’re the criteria we used. Each is something you can verify before you sign anything.

1. Does the free plan stay free? — A 14-day trial is not a free plan. We separated the vendors with genuine free tiers (no card, no expiry) from the ones whose “free” is a countdown. This single distinction eliminated three of the eight tools we considered for this list before we got to anything else.

2. Does the bot learn from your real website? — A chatbot that needs you to paste a 50-line knowledge base into an admin form before it can answer a single question is not actually saving you time. The bots that read your live site and draft their own persona from it are a different category of product, and we weighted that heavily.

3. Setup speed measured in minutes, not weeks. — Every vendor claims fast setup. We checked by asking: how many forms do you fill before the bot can answer one real question? Quick21’s answer is zero forms; you have one conversation with our builder bot. Tidio is fewer than five. Intercom and HubSpot expect a week of configuration; that’s not a criticism, just a fact about who they’re built for.

4. How many visitor languages, automatically? — If your French-speaking visitors get an English welcome message, you’ve already lost most of them. Auto-localisation of the welcome message and suggestion chips, detected from your site’s own language, is table stakes in 2026 but not many vendors actually ship it. Quick21 supports 30+; we name them.

5. What happens when the bot doesn’t know? — A handoff that drops the visitor into your inbox with zero context is worse than no bot at all. We looked at how each vendor passes the conversation, the visitor’s question, and the relevant pages the bot consulted to your team.

6. Per-workspace vs per-seat vs per-conversation. — Pricing structure determines whether the bill grows with your traffic, your team, or stays flat. We flagged where each model bites: Intercom Fin’s $0.99 per resolution looks small until you do 5,000/mo; Tidio Plus jumps from $59 to $749 to unlock real Lyro AI; ChatBot.com is per-user. Quick21 is per-workspace, flat.

None of these criteria are arbitrary. They’re the questions an SMB owner with no procurement team actually has to answer before they sign up, and the ones every vendor’s marketing page goes out of its way to fudge.

The seven AI chatbots for websites, ranked

Quick21 Best overall · 2026

Free plan: 50 conversations & 100 AI responses / month, 2 seats, no card. Pro and Business: contact sales. Per-workspace pricing. Bengaluru, India.

Quick21 is the AI chat your customers actually finish a conversation with. Not because we have the biggest brand or the longest sales-call deck — because the bot sounds like your business by name, greets your visitors in their language, and lives on your site in under two minutes without anyone on your team filling a form.

The single biggest difference between Quick21 and every other tool on this page: when you sign up, you don’t configure the bot — you have a conversation with our builder. You paste your URL, our builder bot reads up to 50 pages of your real website, drafts a persona in your voice, writes 5-6 industry-specific FAQs from your actual content, sets up handoff rules in plain English (“if they ask about refunds, send to me”), and emails you the install snippet. You confirm or tweak in chat. Then you drop one <script> tag on your site. The median time from sign-in to live widget is under two minutes — verified by Playwright end-to-end tests against a real customer onboarding (networkershome.com, an IT training institute in Bangalore: bot drafted CCNA/CCNP-specific persona from their own site copy, 18 pages indexed, six course-specific FAQs ready before they finished their first cup of tea).

The free plan is a genuine free plan, not a 14-day timer. You get 50 conversations and 100 AI responses per month, two seats, the full AI chat widget on your site, and the 30+ visitor-language welcome localisation. Quick21 branding shows on the widget while you’re on Free; that’s the only catch. No credit card to sign up, no expiry on the plan, no “upgrade or your bot disappears” emails after day 14.

Visitor language detection works the way every other vendor claims theirs does, but actually ships. The welcome message and suggestion chips auto-localise based on the language we detect on your crawled site, across 30+ languages including English, Spanish, French, German, Italian, Portuguese, Dutch, Polish, Russian, Ukrainian, Turkish, Arabic, Hindi, Bengali, Tamil, Telugu, Marathi, Gujarati, Kannada, Urdu, Indonesian, Malay, Vietnamese, Thai, Korean, Japanese, Mandarin Chinese, Swahili, Burmese, and Persian. A French bakery’s visitors are greeted in French automatically. A Tamil-Nadu store’s visitors are greeted in Tamil. Your team’s inbox stays in English.

When the bot doesn’t know — or when the visitor asks for a human — the handoff goes to your inbox with the full conversation, the original question, and the pages the bot consulted. You set the trigger phrases in plain English. Quick21’s widget is style-isolated via Shadow DOM, so it never fights with your site’s CSS or breaks your layout. Works on every platform that lets you paste an HTML <script> tag: Shopify, WordPress, Wix, Webflow, Squarespace, custom HTML, Next.js — anywhere.

Per-workspace pricing means your bill doesn’t scale with seats or conversations the way Intercom’s does. The Free plan’s 50 conversations / 100 AI responses cover small sites. When you outgrow it, Pro and Business plans are “contact sales” today — we match the plan to your traffic instead of pre-publishing a price table you’ll outgrow in three months. Real customers get straight quotes; we don’t do annual-discount theatre.

Your data lives in a tenant isolated at the database level, encrypted at rest with AES-256-GCM. Passwords use Argon2id with brute-force lockout. Sessions can be revoked server-side. Standard production posture for a 2026 SaaS, but worth saying — we’d rather be plain than overstated.

Tidio

Free plan with 50 billable conversations + 50 one-off Lyro AI conversations. Paid: Starter $24.17, Growth $49.17, Plus $749/mo. Recurring Lyro AI quota from $32.50/mo for 50 conversations. Wrocław, Poland.

Tidio is the brand-recognition leader in the SMB live-chat category, and that recognition is earned. Their Lyro AI agent does the right things: trains on your own data, handles multiple questions in one conversation, hands off to a human when confidence drops. If you’re a founder who’s seen Tidio in twenty G2 articles and you trust the name, that’s a perfectly reasonable starting place.

The pricing is where the catch shows up. Tidio’s Free plan does include Lyro — but as a one-off allocation of 50 conversations that doesn’t renew month-over-month. After that’s used, you’re on the Starter plan ($24.17/mo) which itself ships with another 50 one-off Lyro conversations. To get a recurring monthly Lyro quota, you add $32.50/mo per 50 conversations on top of the Starter plan, or jump to the Plus plan at $749/mo where Lyro becomes a first-class feature with higher built-in caps.

If you do the math on a small storefront getting, say, 300 AI conversations a month, the Tidio bill works out to roughly $24.17 (Starter) + $195 in add-on Lyro quota = $219/mo. Quick21’s Free plan covers your first 100 AI responses at zero, and the Pro tier is a flat per-workspace fee. Where Tidio fits better: you have a real live-chat team that needs Tidio’s mature inbox UI and you’re already paying the Plus tier for something else.

Worth noting honestly: Tidio’s Lyro is good. It does the thing it claims to do. The objection isn’t the product, it’s the pricing path: it’s cheap to start and expensive to scale, while Quick21 is cheap to start, cheap to scale, and matched to your volume instead of priced in conversation-pack add-ons.

Intercom (Fin AI Agent)

No free plan. 14-day trial. Essential $29/seat/mo, Advanced $85/seat/mo, Expert $132/seat/mo. Fin AI Agent: $0.99 per outcome (resolution), billed on top of seat fees. San Francisco, USA.

Intercom is the platform serious customer support teams reach for once they’ve outgrown chat-only tools and need a proper helpdesk with ticketing, automation, and now Fin — their AI agent. Fin is genuinely good: it’s context-aware, integrates cleanly with Intercom’s helpdesk, and the handoff to a human agent retains everything. If you have a 5+ person CX team and a real ops budget, Intercom is built for you.

The Fin pricing model is the thing every SMB buyer needs to understand before signing. Intercom charges $0.99 per “outcome” — defined as a confirmed resolution, a no-further-help signal, or a completed workflow. That sits on top of the per-seat platform fee, which starts at $29/seat/mo for the Essential plan and runs to $132/seat/mo on Expert.

For a small business doing 2,000 customer conversations a month where Fin resolves 70% of them, you’re looking at $0.99 × 1,400 outcomes = $1,386/mo in Fin fees alone, on top of seat fees. At 8,000 conversations/mo with the same resolution rate that’s $5,544/mo just for Fin. Compare to Quick21’s flat per-workspace Pro plan and the math changes considerably.

Intercom fits if: you’re an established mid-market or enterprise team, you already use Intercom or are migrating from Zendesk, and the per-outcome economics work for you at your volume. Quick21 fits if you’re an SMB that wants flat pricing and a bot that sounds like you on day one without configuring a helpdesk first.

Crisp

Free plan: $0/mo, 2 seats, no AI credits. Mini $45/mo ($5 AI credits), Essentials $95/mo ($25 AI), Plus $295/mo ($75 AI), Enterprise custom. Per-workspace pricing. Nantes, France.

Crisp is genuinely well-loved in the European SMB market — clean per-workspace pricing rather than per-seat, a polished shared inbox, and a generous free tier for the non-AI features. Their AI agent, Hugo, is positioned as a separate product layered on top, with included AI credit allowances rising by tier.

On the Free plan you get the live-chat widget, shared inbox, and team collaboration features with two seats, but no AI credits are bundled. Hugo AI starts contributing at the Mini tier ($45/mo per workspace, $5 included AI credits) and scales up — Essentials at $95/mo ships $25 in AI credits, Plus at $295/mo ships $75. If you’re running a single workspace with low AI volume, this pricing is clean and predictable. If you’re juggling several workspaces or you need a free plan that actually includes AI, the numbers move on you.

Crisp’s biggest structural strength is the per-workspace model — you’re not penalised for adding teammates. Their biggest gap (compared to Quick21) is that the AI agent isn’t the headline product; Crisp is a chat platform that has AI as one feature among many. If your priority is the AI part — bot drafted from your site, multilingual greeting, conversational onboarding — Quick21 leads. If your priority is “a clean shared inbox with European data-residency credibility,” Crisp is well-positioned.

Worth saying plainly: Crisp’s product is solid, their pricing is honest, and their data-protection posture suits European buyers well. The reason Quick21 ranks higher on this specific list is the AI-first orientation and the free plan that includes the full AI chat with no credit-card friction.

Chatbase

Free: 50 message credits/mo, 1 AI agent, 400 KB training data, deletes after 14 days inactive. Hobby $32, Standard $120, Pro $400, Enterprise custom. 20% annual discount. New York, USA.

Chatbase is the AI-only competitor closest in spirit to Quick21 — they don’t pretend to be a helpdesk or a live-chat platform, they’re focused on giving you an AI agent trained on your documents. For doc-corpus-driven bots (think a SaaS with extensive product documentation, or a knowledge-base-heavy business), Chatbase’s training pipeline is genuinely strong: you upload PDFs, paste URLs, point at sitemaps, and they handle the embedding and retrieval.

Where the Chatbase experience differs from Quick21 is in the surfaces around the AI. Chatbase’s Free plan gives you 50 message credits a month and one agent, but auto-deletes the agent if it’s inactive for 14 days. That’s a meaningful restriction for SMB owners who set the bot up, get pulled into other work, and come back two weeks later. The paid tiers start at $32/mo (Hobby: 500 credits), jump to $120/mo (Standard: 4,000 credits), and then $400/mo (Pro: 15,000 credits).

Two operational gaps relative to Quick21: Chatbase doesn’t auto-localise the visitor-facing welcome to 30+ languages from your site’s detected language, and the handoff-to-inbox flow is less integrated than Quick21’s plain-English trigger rules. Chatbase is excellent if your business is “answer questions from our giant doc set” and less excellent if your business is “greet our multilingual visitors in their language and pass the conversation to our team when needed.”

Chatbase fits if: you have a lot of documentation, you primarily need RAG over that corpus, and you’re comfortable building the integration surface around the agent yourself. Quick21 fits if you want the AI plus the conversational setup, the multilingual layer, and the inbox handoff in a single product.

HubSpot Chatbot

Free with HubSpot CRM: rule-based chatflows, 1,000 contacts, 2 users. Breeze AI Assistant available on free tier (CRM-side, not chatbot-side). Marketing Hub paid: Starter, Professional, Enterprise. Cambridge, MA, USA.

HubSpot’s free chatbot is the right choice for one specific persona: you’re already a HubSpot CRM user, you want a chat surface that flows naturally into your existing contact records, and you don’t need the chatbot itself to be AI-powered. The free chatbot builder is rule-based by default — it routes visitors based on the flow you build, captures contact info, and books meetings. For lead-capture, it works fine; for actually answering customer questions in real time, the AI layer happens elsewhere in the HubSpot stack.

HubSpot’s Breeze AI assistant is available on the free tier but it’s positioned as a CRM-side helper (researching companies, prepping sales calls, summarising records) rather than a customer-facing chatbot AI. To get an AI-powered customer chatbot from HubSpot, you typically need to be on Marketing Hub Professional or Service Hub Professional pricing tiers.

Quick21’s positioning is different: the free plan includes the AI-powered customer chatbot directly, not as an upgrade path. If you’re not already on HubSpot, starting with Quick21’s free plan and adding HubSpot later (or never) is the simpler path. If you’re deeply on HubSpot already, the free HubSpot chatbot fits naturally into your existing CRM stack and Quick21 would be an addition rather than a replacement.

Fits best for: existing HubSpot CRM users who want chatflows as a lead-gen funnel into their existing pipeline. Less optimal for: SMB owners who want a real AI chat on their site without first committing to a CRM platform.

ChatBot.com

No perpetual free plan. 14-day trial, no credit card. Starter $52/mo, Team $142/mo, Business $424/mo, Enterprise custom. Conversation-volume tiers; per-user pricing. Wrocław, Poland (same parent as LiveChat).

ChatBot.com is the flow-builder camp’s strongest product. If your mental model of a chatbot is “a decision tree with bot replies at each node, sometimes calling out to an LLM,” this is the tool built around that mental model. Their visual flow builder is mature, the integration surface is wide, and they’re the same Text Inc. that builds LiveChat — so you get the operational maturity of a 15-year-old company.

Pricing reflects the enterprise positioning: Starter is $52/mo with limited conversation volume; Team is $142/mo; Business is $424/mo. There’s no perpetual free plan — only a 14-day trial that requires no credit card to start but ends with a hard upgrade decision. If you’re comfortable building flows by hand and you have a CX team to maintain them, ChatBot.com’s tooling is excellent and the pricing is fair for what you get.

Where Quick21 ranks higher on this list is for the dominant SMB use case in 2026: most small businesses don’t want to build flows; they want a bot that already knows their business and starts answering questions on day one. Quick21 reads your site and writes the bot for you. ChatBot.com asks you to build the bot, then test it, then deploy it. Different philosophies; different buyer.

Fits best for: agencies building bots for clients, larger teams with dedicated bot-ops, or businesses with complex multi-step flows that need explicit branching logic. Less optimal for: SMB founders who want to ship today, not configure for a week.

How to switch to (or start with) Quick21

If you’ve read this far and want to try the page-one pick, here’s exactly what happens after you click “Start free.”

Step 1 — sign in (10 seconds). Click “Continue with Google” or sign up with email. No credit card. No verification call. No procurement form. Your workspace is created the moment you sign in.

Step 2 — paste your URL (5 seconds). The Quick21 Builder bot meets you in chat the moment you land on the dashboard. It asks for your website URL. That’s the only thing you have to type.

Step 3 — watch the builder configure your bot (60-90 seconds). The Builder reads up to 50 pages of your site, identifies your industry, drafts a persona that sounds like your business, writes 5-6 FAQs from your actual content (not templates), localises the welcome message to your site’s language, and proposes 4 suggestion chips for your visitor input. You see each step in the live preview pane as it happens. Total time: under two minutes for most sites.

Step 4 — confirm or tweak in chat (30 seconds). The Builder shows you the draft and asks “Did I get your business right? Want to tweak any of this?” You answer in plain English. Don’t like the persona? Tell it. Want to add an FAQ? Say so. Most teams tweak one or two lines and confirm.

Step 5 — embed one script tag. The Builder shows you the install snippet and emails it to you automatically (so you have it later if you close the tab). Paste it on your site — Shopify theme, WordPress footer, Wix custom code, Webflow embed, Squarespace HTML block, or wherever you put HTML. The widget loads, the bot greets your visitors in their language, and you’re live.

From sign-in to live AI chat on your website: roughly two minutes. Free plan stays free forever — really free, not a trial.

Try the chat your customers will actually finish talking to.

Five mistakes SMB buyers make when picking an AI chatbot

After watching enough buyer journeys, the same five mistakes show up. Calling them out plainly here saves you a month of frustration and a wasted budget.

Mistake 1: confusing “free trial” with “free plan.” A 14-day free trial that requires a credit card and converts to a paid plan automatically is not a free plan. It’s a paid plan with delayed billing. The distinction matters because the trial timer pushes you to decide before you’ve actually tested the bot on your real traffic. A real free plan lets you run the bot for a month, see how visitors interact, and then choose to upgrade based on actual usage rather than a countdown. Of the seven tools on this page, only Quick21, Tidio (with one-off Lyro), and Chatbase (with a 14-day inactivity timer that resets) have anything resembling a real free plan. The rest are trial-based.

Mistake 2: paying for AI you can’t turn on. Several vendors include “AI” in their plan name but gate the actual AI features behind a separate add-on or a higher tier. Crisp’s plans include AI credits at $5-$75 per month depending on tier; Tidio includes a one-off Lyro allocation that doesn’t renew. The visible plan price is not the operating price. Before signing up, calculate: at my expected conversation volume, how much will the AI itself cost? Quick21’s pricing folds the AI into the per-workspace price; you don’t buy AI credits separately.

Mistake 3: choosing the platform with the most integrations instead of the one that fits your stack. “80+ integrations” is impressive in a marketing deck and irrelevant in your actual day. You need the three or four integrations that match your actual stack — your CRM, your helpdesk if you have one, your email provider, maybe Shopify. A vendor with the right three integrations beats a vendor with seventy-five wrong ones. Look for the integrations you’ll actually use, not the count.

Mistake 4: optimising for per-conversation cost when your real bottleneck is implementation time. Most SMB owners we’ve talked to spent more on the consultant who set up their chatbot than on the chatbot itself for the first year. If Tool A is $20/mo and requires three days of configuration, and Tool B is $30/mo and works in 90 seconds, Tool B is meaningfully cheaper after one month. The time cost of implementation is the hidden line item, and it’s where Quick21’s 90-second conversational onboarding pays for itself.

Mistake 5: assuming “more languages supported” means “auto-translates correctly.” Many vendors claim 30-46 language support but ship a UI translation only — the actual bot answer is generated in English and machine-translated character-by-character, producing answers that sound off to a native speaker. The right test: configure the bot for a single language other than English, ask it a real question in that language, and read the answer aloud to someone who speaks it natively. Quick21’s welcome and suggestion-chip localisation is generated in the target language directly (not translated); the AI replies themselves use the same multilingual model end-to-end.

Frequently asked questions

The questions buyers actually have when picking an AI chatbot for their website. Answers below are reflected in the FAQPage schema markup on this page for AI Overview eligibility.

What is the cheapest AI chatbot for a website in 2026?

Quick21’s Free plan stays free forever — no credit card, no expiry, no trial timer. You get 50 conversations and 100 AI responses per month, with 2 seats and the full AI chat widget. Most competitors marketed as “free” are 14-day trials (ChatBot.com, Intercom) or require a paid tier to unlock AI features (HubSpot, Crisp). Tidio’s Free plan technically includes 50 one-off Lyro AI conversations but they don’t renew; after that you need a paid plan to keep AI replies.

Which AI chatbot is best for a small business website?

For small business websites, Quick21 ranks first because the free plan is genuinely free, the bot drafts itself in your brand’s voice from your real website (no template-filling), and the visitor greeting auto-localises to 30+ languages. Tidio is a strong second for teams already wedded to live-chat. Intercom Fin and Crisp Hugo are great if you’re already paying for those platforms. ChatBot.com and HubSpot lean toward larger teams with established workflows.

How quickly can I get an AI chatbot live on my website?

With Quick21, the median is under two minutes: you sign in with Google, paste your website URL, the builder bot reads your pages and drafts your persona, welcome message and FAQs in one conversation, you confirm, and you drop one <script> tag on your site. Tidio is roughly 5-10 minutes once you connect data sources. Intercom and Crisp typically take a week or more to configure properly. ChatBot.com requires you to build flows by hand.

Does an AI chatbot need to know my products or services to be useful?

Yes — and this is where most chatbots fail their first impression. Quick21 reads your actual website during onboarding and writes the bot’s persona, welcome message and FAQs from your real copy: your service names, your tone, your specific facts. Tidio and Intercom can be trained on your knowledge base, but require uploads. HubSpot and ChatBot.com lean on rule-based flows by default.

Can the chatbot greet visitors in their language?

Quick21 auto-localises the welcome message and suggestion chips into 30+ languages based on the language detected on your website. A French clinic’s visitors are greeted in French automatically. Tidio and Crisp support multilingual but typically require manual translation. Chatbase, HubSpot, and ChatBot.com support language switching but don’t auto-detect from your site.

What happens when the AI bot doesn’t know an answer?

Quick21 hands off the full conversation, the visitor’s question, and the pages it looked at to your team inbox the moment a human should take it. You set the handoff triggers in plain English (“if they ask about refunds, send to me”). Every competitor here supports some form of handoff, but the context-passing varies: Intercom is best-in-class on this for paid plans; Tidio and Crisp do it well; ChatBot.com and HubSpot route based on flows.

Can I customise the chatbot to match my brand?

Yes. Quick21 supports custom colors, position (bottom-right / bottom-left), launcher text, your logo, agent avatars, welcome message, and suggestion chips. The widget is Shadow-DOM isolated so it never fights with your site’s CSS or breaks your layout. Most competitors on this list offer similar customisation on their paid tiers; on the Free plan, Quick21 shows a small “powered by Quick21” line, which is removable on Pro.

What platforms does it work on?

Any website that lets you paste an HTML <script> tag. That covers Shopify, WordPress, Wix, Webflow, Squarespace, custom HTML, Next.js, Astro, Hugo, Jekyll, or any other static or dynamic site.

Author. Quick21 makes one of the products in this comparison, so we’re structurally biased. We disclose that upfront and we kept competitor sections short by policy (max 500 words each) so this article didn’t become a free ad for any vendor. The verdict reflects our honest view of the SMB website-chat market in 2026.
