About

Langflow is an MIT-licensed platform for building and deploying AI agents and workflows, with a visual editor and Python source access to customize any component. Flows can be served as an API or as an MCP server, and the README lists multi-agent orchestration and observability integrations such as LangSmith and LangFuse. It runs as a Python package, a Docker container or a Windows and macOS desktop app, and the website mentions a free cloud account.

Use cases: agent-orchestration, workflow-automation
