A free chatbot sounds unbeatable: zero budget, 20-minute setup, and the illusion of being able to reply to customers 24/7 without spending a penny. Reality is more nuanced. Tight quotas, third-party branding inside the conversation, WhatsApp billed separately: the real costs creep in through the back door. This guide compares the 8 truly usable no-subscription chatbots in 2026, their precise limits, and the threshold above which a £79/month flat plan becomes mathematically more cost-effective than free.
Free chatbot: what we're really talking about
The term "free chatbot" covers three very different tool families — and the customer experience is nothing alike from one family to the next.
1. The website widget (chat box)
A small chat button in the bottom-right corner of your site that opens a mini-window. The visitor types, you (or an automated script) reply. Typical tools: Tidio, Crisp, Tawk.to. Great for e-commerce and brochure sites — useless if your customers mostly reach you through WhatsApp or phone.
2. The scripted conversational agent (decision tree)
You configure a tree of questions and answers in advance: "Hello! What can I help with? 1. Book an appointment 2. Request a quote 3. Talk to someone". Typical tools: ManyChat (free tier), Landbot. Great to qualify simple leads, terrible at handling a real tradesperson enquiry.
3. The AI conversational agent (LLM-based)
An AI understands natural language and replies fluidly. Typical tools: ChatGPT free version (manual integration), Botpress Cloud, open-source self-hosted AI agents. More powerful — but none include WhatsApp on the free tier, and quotas burn through fast.
The 8 free chatbots really usable in 2026 — comparison
Here are the 8 no-subscription tools genuinely workable for a small business, freelancer or local shop in June 2026. Prices and limits verified on June 1st, 2026.
8 free chatbots: quotas, channels, branding
| Tool | Free quota | Channels | Branding |
|---|---|---|---|
| Tidio Free | 50 conv./month | Website | Visible |
| Crisp Free | 2 seats max | Website | Visible |
| Tawk.to | Unlimited | Website | Visible (removal = £16/month) |
| Landbot Sandbox | 100 conv./month | Web only | Visible |
| Botpress Cloud Free | 2,000 messages/month | Web, Messenger | Visible |
| Chatfuel Free | 50 users/month | Messenger, Instagram | Visible |
| HubSpot Chatbot Free | Unlimited (CRM-tied) | Website | Visible |
| ChatGPT (DIY integration) | Interface convos only | None (manual setup) | Absent (self-integrated) |
Prices and quotas verified on June 1, 2026. Subject to change.
Three immediate conclusions come out of this table. First, no free chatbot offers WhatsApp included — it's systematically a paid add-on. Second, third-party branding stays on 7 tools out of 8 — a detail that radically changes how customers perceive your business. Third, monthly quotas are calibrated to push you toward paid plans the moment you start actually using the tool (50 to 200 conversations/month).
The 5 hidden limits no one mentions
Before buying into the "free" promise, let's review the constraints vendor homepages never display — but that transform the experience after 4 to 6 weeks of use.
1. Third-party branding as an amateur signal
"Powered by Tidio", "Powered by Tawk.to", "Free chatbot by Chatfuel": these mentions stay visible in every customer conversation. According to a Salesforce 2024 study, 1 prospect in 4 loses confidence in a business whose chat tool displays a third-party brand. The effect is even sharper for tradespeople and personal services, where credibility hinges on personalisation.
2. WhatsApp billed separately, 100% of the time
No free chatbot includes WhatsApp Business API. The reason is simple: Meta charges every conversation through its official API between £0.03 and £0.12 depending on the country and message type. On 1,000 conversations/month (a typical volume for a tradesperson or restaurant), that means £30 to £120/month on top of the chatbot — which mechanically kills the "free" promise. Our full WhatsApp Business API guide details the 2026 pricing grid.
3. The 50–200 conversations/month wall
On Tidio, Crisp, Landbot and Chatfuel, the free quota runs out between 50 and 200 monthly conversations. For a hairdresser handling 8 to 12 enquiries per day, the limit is crossed in 10 to 15 days. For a restaurant at 50 enquiries/day, three days. The consequence: your chatbot silently breaks down at the very moment you need it most.
4. No integrated calendar
The #1 need for a tradesperson or a clinic is to book appointments — not to answer questions. Yet no free chatbot includes a calendar synced with Google Calendar, iCal or Outlook. You need to wire one up through Zapier (paid above 100 tasks/month) or redirect manually to Calendly. Our comparison on how to pick an appointment scheduling software details available integrations.
5. No customer memory (zero CRM)
A free chatbot treats every conversation as isolated. No history, no link to a customer file, no follow-up possible. The day you want to reach back out to the 50 prospects discussed last quarter, you're left with nothing. That's the structural gap between a pure chatbot and a full WhatsApp CRM.
Which trades can really use a free chatbot?
Not every profile is penalised the same way by free limits. For some use cases, a free tool still works — for others, it's a false economy.
When free is enough (really)
- A very low-traffic brochure site (under 500 visits/month) with a static FAQ. Tawk.to or HubSpot Chatbot Free do the job.
- A product testing phase, over 4 to 6 weeks, to validate that there's really conversational demand.
- A B2B-only business with few inbound prospects and a long sales cycle (fewer than 20 conversations/month).
When free becomes a trap
On the flip side, free is mechanically counter-productive for most local-services trades. If you're a hairdresser or beauty professional, your need is to turn every Instagram or WhatsApp message into a booked slot — exactly what web widgets don't do. If you're a restaurant owner, you receive 30 to 80 daily enquiries (bookings, allergies, opening hours) — you blow the free quota in 48 hours. And if you're a garage or body-shop owner, every missed call equals £200 to £600 of lost repair work, and third-party branding makes customers doubt your professionalism. For these three trades, the combined bill (WhatsApp API + branding removal + calendar integration) quickly exceeds £100/month — more than a fully-bundled WhatsApp assistant.
The hard threshold where "free" costs more
Here's the hard maths between staying on a free chatbot and switching to a £79/month all-in plan.
Real monthly cost of a "free" chatbot by volume
Based on Meta WhatsApp API 2026 pricing + quotas observed across 12 tools.
Mathematical conclusion: above 120 WhatsApp conversations/month or 300 web conversations/month, a £79/month flat plan becomes strictly cheaper than stacking free tiers + add-ons. And the quality (no third-party branding, integrated calendar, CRM, real-time alerts) doesn't even compare.
"The word 'free' is poorly calibrated for small businesses. What counts is total cost of ownership — visible branding, WhatsApp billed separately, quota saturated in 10 days. Over 90 days, free always ends up more expensive than a clear flat plan."
Checklist: 7 questions to ask before choosing a free chatbot
- Do customers mostly contact you via WhatsApp? If yes, no free chatbot will work without hidden costs.
- How many conversations do you receive monthly? Under 50, free holds. Above, you saturate.
- Does third-party branding bother you? If you're a tradesperson or premium service, yes — it weakens your image.
- Do you need calendar integration? If yes, budget Zapier or a dedicated booking tool on top.
- Do you want to keep conversation history? No free chatbot offers a real built-in CRM.
- Are you going to follow up with prospects? Automated customer follow-up is non-existent on free tools.
- Do you have time to configure 4 different tools? Stacking 4 free tools takes 3× more setup than a single paid tool.
With Reepli: all-in-one WhatsApp at £79/month, no third-party branding
Reepli.ai isn't a free chatbot — it's a fully-bundled WhatsApp assistant built for small businesses, tradespeople and shop owners who want a serious tool without stacking 4 subscriptions. Concretely:
- Official WhatsApp included in the plan — no per-conversation surcharge.
- Integrated calendar (Google, iCal, Outlook) to book appointments directly in the chat.
- Lightweight CRM with customer history, tags and automated follow-ups.
- Google review requests sent automatically after a service — with suggested response drafts you validate.
- Full white labelling: the conversation shows your name, not ours.
The trade-off is mathematical: £79/month flat vs. £45 to £200 of cumulative cost stacking free tools + WhatsApp API + calendar integrations.

5-step plan to choose well
- Step 1: list your last 30 inbound contacts. Which channel (WhatsApp, Instagram, site, phone)?
- Step 2: count the monthly volume and project to 6 months.
- Step 3: list the 3 expected actions (booking, quoting, follow-up, review request).
- Step 4: if a free chatbot covers those 3 actions with no hidden costs and under 50 conv./month, go with Tawk.to or HubSpot Free.
- Step 5: if you exceed 100 conv./month or WhatsApp is central, jump straight to a bundled WhatsApp assistant — payback is 2 to 3 months.
A free chatbot isn't a trap per se — it's just poorly calibrated for most local small businesses. The right reflex in 2026: start by measuring your real volume and dominant channel, then pick the tool that survives 6 months of use without hidden costs. Often, "free" isn't the winner.
