Langflow 1.4 introduces Projects, a new way to organize, modularize, and expose AI workflows, making it easy to share tools over MCP. With this release, Langflow Desktop turns your machine into a local AI agent factory, allowing you to build, test, and run flows entirely on your desktop. Projects enable a unified space where shared flows can "talk" to each other, accomplishing tasks and gradually adding functionality to turn a Project into the central hub for managing flows, execution, logs, and task orchestration. Langflow is now a first-class citizen in the MCP ecosystem, acting as both a builder and aggregator of MCP tools, allowing users to create, adapt, and orchestrate them with fine-grained control over each tool's behavior. Langflow Desktop provides a full agent development environment, and the project is open-source, evolving fast thanks to community support.
