DrawX vs GitDiagram: an editable file you own vs a one-shot image.

GitDiagram is a great free tool for visualizing a public repo as Mermaid. DrawX picks up where it ends: editable draw.io output, multiple inputs, and stakeholder-ready exports.

What GitDiagram is great at

  • Open source (MIT) and free to self-host
  • Fast 'paste a repo URL, get a Mermaid diagram' experience
  • Great for a quick visual when Mermaid is your end format

Why DrawX

  • Your output is a native draw.io file you can refine forever — not a screenshot
  • Beyond repos: drop in a PDF, a URL, an image, or a sentence
  • Eight diagram types auto-detected per repo
  • Export to PNG, SVG, .drawio, and PowerPoint for docs and decks
  • Projects, pages, comments, version history, sharing — collaboration baked in

Use GitDiagram for a quick Mermaid sketch. Use DrawX when the diagram has to be edited, shared, and shipped.
