What is reladraw?

reladraw is a free, open-source diagram language that sits between Mermaid and draw.io. You describe boxes and arrows in plain text with relative positions such as below or right of, and it renders a clean SVG, so you get custom layouts without dragging shapes around by hand.

Third-party open-source projects. We are not affiliated with their authors; repositories are provided as-is by their maintainers. Review each project's license, code and security before installing. See our Disclaimer.

Pros: what reladraw does well

  • You control the layout in plain text
  • Try it in the browser or via CLI
  • Free and open source

Cons: where it falls short

  • A new syntax to learn
  • Smaller ecosystem than Mermaid

Who reladraw is for

Developers and writers who want precise, version-controlled diagrams without manual drawing.

Who can skip it

People happy with auto-laid-out Mermaid charts or a drag-and-drop canvas.
