"Free" is the most over-claimed word in the live chat market. Half the platforms that advertise free live chat software are really offering a 14-day trial; the other half offer a genuine free tier but bury crippling limits in the fine print. This guide cuts through it and tells you which free plans are actually usable in 2026 — and where each one starts to hurt.
What "free" should mean
A real free live chat plan should let you:
- Install a chat widget on your website with no time limit.
- Talk to customers in real time with at least one agent seat.
- Store and read back conversation history.
- Capture a visitor's name and email.
If a plan does not do all four without a credit card, it is a trial dressed up as a free plan. Treat it accordingly.
The contenders
tawk.to
Genuinely free, forever, with unlimited agents. That is rare and worth respecting. The trade-offs are a dated widget UX, weak AI, and the fact that your data lives in their cloud on their terms. Removing the branding costs money. Fine for a side project; think twice if you handle a lot of personal data.
Tidio
A real free tier with a modern widget and a strong Shopify integration. The free plan caps the number of monthly conversations and the AI replies, so a busy store outgrows it fast — but for a new D2C brand it is a clean place to start.
Crisp
Free plan covers two seats and the core inbox. Tasteful product. The AI and automation features are mostly gated behind paid tiers, so on free you are really getting plain live chat rather than a Smart Chatbot.
HubSpot
Free live chat is a doorway into HubSpot's CRM. If you already live in HubSpot it is a no-brainer; if you do not, you are adopting a whole CRM to get a chat bubble.
Silux Chat (us)
Our free plan includes 1,000 messages a month, 2 bots, a website widget and a Smart Chatbot trained on your own knowledge base — not just canned replies. It is UK-based with UK data residency and a DPA available without forcing you onto an enterprise contract. Honest take: 1,000 messages is plenty for a small site but a high-traffic store will move to a paid plan; see /pricing for where the tiers land.
How the free tiers really compare
| Platform | Time limited | AI on free | Data residency | Branding removable on free |
|---|---|---|---|---|
| tawk.to | No | Minimal | Their cloud | No |
| Tidio | No | Limited | EU/US | No |
| Crisp | No | No | EU | No |
| HubSpot | No | Limited | US/EU | No |
| Silux Chat | No | Yes (KB-grounded) | UK | No |
Where free plans bite
Free tiers are designed to convert you. The common pinch points are:
- **Message or conversation caps.** A viral week can blow through a monthly limit in days.
- **One or two agent seats.** Add a third teammate and you are paying.
- **No data residency choice.** This matters more than vendors admit for UK and EU businesses processing customer data.
- **AI gated behind paid tiers.** Plain live chat is useful, but a bot that answers from your knowledge base is the feature that deflects tickets — and it is often paywalled.
Our recommendation
If you want genuinely free and unlimited agents and you are not precious about polish, tawk.to is unbeatable on price. If you run a Shopify store, start on Tidio's free plan. If you are a UK business that wants a free Smart Chatbot grounded in your own content, with UK data residency and an easy path to handover, start on Silux Chat's free plan and read /features before you commit. Whatever you pick, test two or three free plans with your real customer questions before paying anyone a penny.
