It supports three ways of working on one canvas: freehand drawing with shapes, connectors, ink, images and charts; writing the diagram as code in Mermaid, D2 or Structurizr; or letting an AI agent build and edit it live through the Model Context Protocol. Text and canvas stay in sync, so you can start with a snippet and finish with something visual. A standout v2 feature maps a public GitHub repository directly in the browser: paste an owner/repo URL and OpenFlowKit reads the files, produces boxes and connections, and cites each arrow back to the exact line of code it came from. Private repositories can be mapped locally through the CLI. The result is architecture documentation that reflects the code rather than someone's memory of it. OpenFlowKit is also practical for day-to-day diagramming: a toolset of 29 MCP tools for agents, C4 context/container/component views that stay connected to one underlying model, automatic matching of 2,000+ cloud and developer icons by node label, animated SVG/GIF/MP4 export, share links and self-hosting. It is MIT licensed, runs locally by default and needs no account. **Pricing & Plans:** Free and open source under the MIT licence. There is no paid tier on the site; you can start creating without signing up, and the code can be self-hosted. - **Repo-to-map generation:** Paste a public GitHub repository and OpenFlowKit reads its files in the browser to draw modules and connections, with every arrow cited to the source line it came from. - **Agent-native canvas over MCP:** 29 diagram tools for Claude Code, Codex, Cursor, VS Code, Windsurf or any MCP client, so an agent can draw on the diagram you have open, one undo away. - **Diagram as code:** Write or paste Mermaid, D2 or Structurizr; the text and the canvas remain the same diagram, so you can round-trip between syntax and visuals. - **Connected C4 model views:** Move from system context to containers to components in linked views that all stay grounded in a single architecture model. - **Icon matching and motion export:** Label a node 'PostgreSQL' or 'Kubernetes' and the right icon is matched automatically from 2,000+ cloud and developer icons; export animated SVG, GIF, MP4 or WebM for living documentation. **Strengths:** Free, MIT-licensed and local-first with no account required; Unique repo-to-diagram mapping that cites each connection back to code; Works equally well for hand drawing, diagram-as-code and AI-agent workflows; Strong ecosystem coverage with automatic matching of 2,000+ cloud and developer icons **Limitations:** No hosted paid support or managed cloud option is advertised, so teams self-host; Advanced MCP and CLI repo mapping assumes comfort with developer tooling; C4 model depth and multiple views can feel heavy for quick one-off sketches [Profile (Markdown)](https://openaitools.app/tool/openflowkit.md) ## Speechify Speechify is a voice AI assistant built around listening, reading and writing with your voice.
