# Langflow

A platform for building and deploying AI agents and workflows in a visual editor, where each flow can be served as an API or an MCP server.

Langflow provides a visual builder for AI agents and workflows, with a playground to test flows step by step. Every component can be customized in Python, and flows support multi-agent orchestration with conversation management and retrieval.

Flows can be deployed as an API, exported as JSON for Python apps, or served as MCP servers so that MCP clients can use them as tools. It works with major LLMs and vector databases and integrates with observability tools such as LangSmith and LangFuse.

Langflow installs with uv or Docker, and Langflow Desktop is available for Windows and macOS. It is MIT licensed.
