Built on Mermaid.js, the open-source project with 90k+ stars on GitHub, it stores diagrams as plain text, so they live in your repo, version with your code, and can be read and written by Claude, ChatGPT, Gemini, Cursor, GitHub, and more. Mermaid AI brings code, a visual canvas, and AI together in one editor. Mermaid Flow goes one step further and runs them: your workflow diagram becomes a working workflow.

Review Mermaid?

Reviewers mostly praise Mermaid Chart for turning text or markdown into diagrams quickly, with less manual layout work and strong fit for documentation, system design, team discussions, and developer workflows like GitHub and infrastructure projects. They repeatedly call it simple, flexible, well documented, and easy to integrate, with some saying it speeds up diagramming dramatically. The main caveats are that the syntax can feel clunky at first, some UI controls like text and border styling seem limited, and as a standalone paid tool it may feel less compelling beside bundled alternatives.
