Chainlit

As a conversational AI framework, Chainlit differs from most chatbot kits by pairing the build step with observability and analytics for LLM apps.

Chainlit is a framework and platform that helps developers and enterprises build, evaluate, and improve conversational AI applications.

You can ship what you build in several forms: a standalone web app, an embedded copilot, a FastAPI server, a custom React frontend, or a bot for Slack, Discord or Teams.

That spread of deployment targets is the main practical draw.

Chainlit also includes authentication and customization options, and it connects with popular frameworks and LLM providers, so you are not locked to one model vendor.

The analytics matter most once real users arrive, because they show how conversations go and where they fail.

Pricing is enterprise, so this chatbot framework looks built for teams more than hobbyists who want a quick prototype.
