Langflow is an open-source, Python-based, low-code platform for building agentic and retrieval-augmented generation (RAG) AI applications. It provides a visual drag-and-drop editor to connect and configure components into functional flows, supporting major LLMs, vector databases, and a growing library of AI tools. Flows can be tested in a Playground, run via an API, or deployed to production, either self-hosted or on a cloud platform.
