Pure Rust LaTeX math layout engine targeting native apps, WASM, and servers without a WebView, shipping SDKs for iOS, Android, Flutter, and React Native.
Key Takeaways
Single Rust layout core emits a flat display list consumed by CoreGraphics, Skia, or Canvas 2D; identical output via native FFI and WASM.
CI runs golden-suite pixel diffs against KaTeX reference images; support table lists full coverage side-by-side.
Zero JS bundle cost for the core (WASM only); KaTeX ships ~280 kB and MathJax ~500 kB of JavaScript.
Built-in mhchem-style \ce and \pu for chemistry and units – a gap in swiftMath, flutter_math, and iosMath.
Memory model is predictable (no GC in hot path), relevant for mobile UI frame budgets and CI raster tests.
Hacker News Comment Review
No substantive HN discussion yet; the one comment positions RaTeX alongside Typst and MicroTeX as Rust-based TeX alternatives, without technical critique.
