Overview
Langflow is a Python 3.10 to 3.14 visual builder (uv pip install langflow, or the langflowai/langflow Docker image on port 7860) for agents and LLM workflows. Every component is editable Python, flows run in an interactive playground, and a finished flow can be served as an API, exported as JSON for Python apps or exposed as an MCP server. Multi-agent orchestration and LangSmith or LangFuse tracing are built in.
Who it is for: Developers prototyping agent flows who want Python under the hood
Strengths
- Any flow becomes an API endpoint or an MCP server for MCP clients
- Component source is Python you can edit inside the builder
- One container on port 7860; no other service in the quick start
- MIT license; desktop builds for Windows and macOS
Weaknesses
- README names no model providers, vector stores or resource needs
- No root Dockerfile or compose file; container config lives in the docs
- Enterprise-ready claim is not detailed in the README
What it needs
- no GPU
- Docker + Compose
- port 7860
