View on GitHubLangflow is a powerful tool for building and deploying AI-powered agents and workflows.
Langflow is an open-source visual platform for building and deploying LLM agents and workflows. It combines a drag-and-drop React Flow canvas with Python component customization, then ships each flow as a REST API, an MCP server, or exportable JSON.
