There's no single 'best' AI chatbot — it depends on your business. If you're a small or medium-sized business looking for a chatbot that speaks fluent, natural language, runs GDPR-proof on EU servers and goes live without hassle, then Alvoru is a strong choice: there's a free tier (50 messages/month) and the paid plans start from €20 per month (Starter €20, Groei €50, Pro €100; 2 months free yearly), including AI, leads and installation in a single line of code.
Do you need a large contact center or complex integrations? Then platforms like Trengo or Chatlayer (Sinch) make more sense, though their rates are considerably higher. Below we compare all five honestly — including what we couldn't confirm with certainty.
Figures verified in July 2026. Amounts in US dollars (e.g. Tidio) are not a 1-to-1 euro conversion; 'conversations/messages' may be counted differently by each provider. Providers' prices and terms change regularly — always check the provider's current page.

We don't misrepresent anyone. This is where Alvoru makes the difference for small businesses.
Where a competitor is a better fit — for example a large contact center with Trengo or Chatlayer — we'll simply tell you so.
For small businesses and freelancers who want to start quickly, affordably and GDPR-compliant — with a free tier to test risk-free and paid plans from €20/mo (Starter €20, Growth €50, Pro €100) for the full product.
A strong multi-channel platform (chat, WhatsApp, email, social) for teams that want every channel in one inbox. The entry price is higher and AI conversations may be billed separately — better suited to larger customer-service teams.
Popular with online stores and small teams, with a free entry point. The AI agent (Lyro) is limited in the free plan and comes as a paid add-on or in higher tiers — check how much AI volume you need.
A platform with GPT-4 chatbots, EU hosting and ISO 27001. A full-featured alternative for EU businesses; the entry price is €99/mo (annual) and rises to higher tiers for more features.
An enterprise conversational-AI platform with 100+ languages and deep integrations. Powerful, but with an enterprise price tag and implementation project — meant for large organizations, not the average small business.
