1. Tidio
Tidio fits a small team that wants bots and one inbox together: the Flow builder is free to start, Lyro learns from your own pages and hands hard questions to a person. The catch: the OpenAPI endpoints wait for the Plus plan, from $300 a month.
Best for: Small teams that want a no-code bot, an AI agent and one inbox. Prices, facts and sources
2. Botpress
Botpress suits teams that want a drag-and-drop builder, knowledge from their own website and files, and an HTTP Chat API. The free plan is capped at 100 conversations, and the first plan with 1,000 or more conversations is Team at $750 a month. Voice is listed only on the quote-only Enterprise plan.

3. Typebot
Typebot suits builders who want a visual canvas, a documented chat API and low entry prices. Starter at $39 a month covers 2,000 chats and removes branding.

4. Microsoft Copilot Studio
Copilot Studio suits organisations that already run Microsoft 365 and Azure, want a visual topic builder, and need Teams, web, WhatsApp or phone channels. A $200 monthly pack of 25,000 credits sits far above the 1,000-credit bar, but credits are a different unit from conversations. No free plan is listed to publish on, and Instagram is not named as a channel.
Best for: Organisations already on Microsoft 365 and Azure. Prices, facts and sources
5. Chatling
Chatling suits small teams that want a low-priced bot with a free plan, a visual flow builder and handoff to a person. Starter covers the API and analytics for $21 a month on yearly billing.

6. Landbot
Landbot suits small teams that want to lay out a bot on a visual canvas and pass chats to people in a shared inbox. The AI agent answers from your files and web pages.

The catch: setup is written instructions and settings, not a visual flow canvas.

9. Voiceflow
Voiceflow suits teams that want a visual builder with a knowledge base, API steps and handoff to contact-centre tools, on web chat, WhatsApp and phone. Plan prices are not public, so you cannot compare cost without contacting sales. The catch: the Free plan is a one-time credit grant that the docs call unsuitable for production.
Best for: Teams that want to design chat and phone agents visually and connect them to a contact-centre or help desk tool. Prices, facts and sources
10. CustomGPT.ai

11. Chatfuel
Chatfuel suits businesses that sell in WhatsApp and Instagram chats and want a bot that answers from a knowledge base, with live chat for staff. Every plan includes every feature and unlimited contacts. The catch: AI usage is metered in dollars, not conversations, so cost at 1,000 chats is not published, and the closed website widget always shows the Chatfuel icon.
Best for: Small businesses and agencies that sell through WhatsApp and Instagram messages. Prices, facts and sources
12. Google Conversational Agents (Dialogflow CX)
Dialogflow CX suits teams on Google Cloud that want a visual flow builder, webhooks and a documented API. Billing is per request, with no plan that includes a set number of conversations.
