A diagram your build can produce.
Render in a native process and keep the SVG alongside your other build artifacts. No headless browser needs to start, and the result can travel with the page or document that uses it.
Use it from the command lineMermaid diagrams, rendered in Rust.
Turn diagram text into standalone SVG for your documentation, application or build. Ferrigura runs without a browser process and embeds the fonts it uses, while keeping labels as selectable text. Start with the Rust library or the command-line tool.
Labels stay text. Fonts travel with them.
Text is measured with bundled fonts, then the glyphs it needs are embedded in the SVG. Labels stay selectable and searchable, with line breaks tied to the same typography the viewer receives.
Understand the output contractA few lines become a diagram.
Choose a flowchart, sequence or state diagram. Each preview is SVG generated by Ferrigura’s native CLI from the source beside it.

The examples use the renderer’s light scheme and embedded font subsets. The website switches between build-time outputs; it runs no diagram renderer in your browser.
Familiar diagram text. Explicit rendering choices.
Ferrigura ports Mermaid 12.2.0. Its type reference documents the supported syntax, layout and limits for each diagram.
Diagrams for different questions
Flowcharts, sequences, classes, states and entity relationships sit alongside the other supported diagram types.
Geometry checked against Mermaid
The verification harness compares parser models and rendered geometry with the pinned upstream implementation in Chromium.
One renderer, many inputs
Reuse resolved configuration across diagrams. Give inline SVGs unique IDs so their styles and references stay scoped.
Repeatable output
Fixed randomness and per-render state support reproducible output. For gantt diagrams that depend on today, Rust callers supply the clock explicitly.
Choose it with the boundaries in view.
Ferrigura produces SVG. Labels use SVG text rather than HTML, and the renderer has no browser callbacks or tooltips. Math labels, hand-drawn strokes, classic themes and some font coverage are outside the supported scope.
The Node.js addon can be built from the repository; its prepared @ferrigura/core package is not available from npm. Ferromark’s optional adapter renders Mermaid fences in custom builds, alongside its Markdown renderer.
Add rendering to your Rust application.
Pass diagram text and configuration to the library. Reuse a renderer when you have several blocks to process.
cargo add ferriguraGive your build an SVG file.
Use the native CLI with files or standard input. Render several inputs into an output directory with one command.
cargo install --locked ferrigura-cli
