It handles the plumbing of message routing, async execution, and real-time bidirectional communication via WebSocket, letting you focus on the conversation logic itself.\n\nYou write Python functions decorated with Chainlit handlers (like @cl.on_message) that receive user input and send responses back to the browser. The framework manages the UI, session state, and async orchestration. It's designed for building chatbots, agents, and copilots that integrate with language models and external tools, and includes support for intermediate steps, tool calls, and streaming responses.","worth_installing":"Yes, if you need to rapidly prototype or deploy a conversational AI application with a web UI and are comfortable with Python async patterns. The low install friction, active maintenance, and permissive license make it a practical choice. The large dependency footprint (24 packages) and community-maintained status (as of May 2025) are trade-offs to accept if the UI and async orchestration features justify the overhead for your use case."},"id":"chainlit","links":{"html":"https://skillfed.io/packages/chainlit","md":"https://skillfed.io/packages/chainlit.md","pypi":"https://pypi.org/project/chainlit/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-04-22","license_spdx":null,"license_treatment":"permissive","name":"chainlit","python_support":"supports_current","summary":"Build Conversational AI."},"popularity":{"monthly_downloads":789417,"position":5055,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.11.1"}
