A pure Rust renderer for Mermaid diagrams that outputs SVG without requiring a browser or Node.js. It supports 23 diagram types and is dramatically faster than mermaid-cli, usable both as a CLI tool and a Rust library.

Use cases

  • render mermaid diagrams to svg without a browser
  • batch render hundreds of mermaid files quickly
  • replace mermaid-cli in a docs build pipeline
  • render mermaid diagrams in a rust program
  • generate flowcharts and sequence diagrams from ci
  • speed up markdown documentation diagram builds

When to choose

  • you need fast, headless Mermaid rendering without Puppeteer/Chromium
  • you render many diagrams in CI or batch jobs and browser startup dominates
  • you want a Rust library for diagram rendering

When to avoid

  • you need pixel-perfect output identical to mermaid-cli for all diagram types
  • you rely on Mermaid features not yet supported among the 23 diagram types
  • you need a battle-tested, mature renderer
