## About Langflow
Langflow is an open-source platform for building and deploying AI agents and workflows. Flows are assembled in a visual editor, every component can be customised in Python, and an interactive playground tests them step by step; finished flows deploy as an API, export as JSON, or run as an MCP server that exposes them as tools. It supports the major LLMs and vector databases, integrates with LangSmith and Langfuse for observability, and offers a desktop app for Windows and macOS.

## Install

```
uv pip install langflow -U
```
