Description

OpenFlowKit is a 100% free, open-source diagram engine designed for engineers, architects, and product teams. It allows users to create professional architecture diagrams and flowcharts using either a visual drag-and-drop interface or 'Diagram as Code' with Mermaid.js and a type-safe DSL. Powered by React Flow, it offers a local-first experience where data stays on the user's machine, requiring no signup or cloud synchronization. It also features an AI assistant called Flowpilot for chat-based diagram editing and a unique Figma export that provides editable vector shapes.
