Free, open-source diagrams you and your agent edit together
OpenFlowKit 2 is a versatile, open-source diagramming platform designed for collaborative visual modeling. Hosted entirely in the browser, it offers a local-first experience that requires no account setup, making it accessible and privacy-focused. Users can create diagrams in multiple ways: drawing directly on the canvas, writing code, or pasting Mermaid, D2, or Structurizr scripts. Its integration with AI providers and local models allows for intelligent assistance, and the ability to hand diagrams off to coding agents like Claude Code facilitates seamless development workflows. Additionally, OpenFlowKit 2 supports version control by pulling diagrams directly from GitHub repositories, with arrows citing specific files and lines, and includes CLI tools for drift detection during CI processes. This makes the tool ideal for developers, designers, and teams seeking a flexible, open-source solution for technical diagrams, architecture, and documentation that integrates smoothly into their existing workflows.
