Langflow
Visual flow builder and Python API for agents, RAG, and MCP-compatible workflows
View on GitHubWhat it solves
Iterating on complex agent graphs faster than code alone allows: build the topology visually, then export it as a deployable Python application you can version and test.
Overview
Langflow is a visual agent and pipeline builder maintained by DataStax. Unlike Flowise, Langflow is also a Python framework; the same graph you build visually compiles to importable Python code you can run in CI or extend in code. MCP-compatible, supports any LLM or vector store, and ships a hosted cloud tier alongside the self-hosted option.

Where to start
The base package shows how visual nodes map to Python components, understanding this bridge is the key to knowing when to build in the UI versus writing a custom component.
