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
