What is Chainlit?

Chainlit is an open-source framework designed to help developers build conversational AI applications quickly and efficiently. Created by the Chainlit team, it solves the problem of integrating AI models into user-friendly chat interfaces with minimal boilerplate code. The core capabilities include a Python SDK for building chat apps, built-in authentication, deployment options as standalone web apps or embedded copilots, and integrations with popular LLM providers like OpenAI, Mistral, LangGraph, and LlamaIndex. It also supports customization of the frontend and creation of custom chat components. Chainlit is ideal for developers and enterprises looking to ship ambitious and reliable AI applications, from simple chatbots to complex multi-step conversational workflows. The framework is trusted by over 50,000 monthly developers and has a strong community on GitHub and Discord.
