What is Langflow?
Langflow is a low-code platform for building and deploying AI agents and MCP servers. It is presented as including batteries included, with support for major LLMs, vector databases and a growing library of AI tools.
You build applications by arranging visual flows from reusable components instead of writing boilerplate code. Python can be used to customize any component. Ready-made flows and components can be run, shared and collaborated on, and a single agent or a fleet of agents can be given access to your components as tools. Flows can also be exposed as an API, and apps can be deployed to a cloud platform or to your own infrastructure, with the same product in its open source and cloud versions.
