Why I Use It
I used Chainlit for a SaaS Business Plan Agent where seeing the agent's reasoning mattered. It displays tool calls, streaming responses, and conversation history in a clean interface. Building all that from scratch would take days. The built-in authentication and deployment options save time.
When I Recommend It to a Client
When they need AI agents with transparent reasoning—users should see what the agent is doing. Also for internal tools where teams need to monitor agent behavior.
