Langflow is a powerful tool for building and deploying AI-powered agents and workflows. It provides developers with both a visual authoring experience and a built-in API server that turns every agent into an API endpoint that can be integrated into applications built on any framework or stack. Langflow comes with batteries included and supports all major LLMs, vector databases and a growing library of AI tools.

Highlight features

  1. Visual Builder to get started quickly and iterate.
  2. Access to Code so developers can tweak any component using Python.
  3. Playground to immediately test and iterate on their flows with step-by-step control.
  4. Multi-agent orchestration and conversation management and retrieval.
  5. Deploy as an API or export as JSON for Python apps.
  6. Observability with LangSmith, LangFuse and other integrations.
  7. Enterprise-ready security and scalability.
