hi, I built a cross-platform native LaTeX math renderer written in Rust. Most mobile math rendering relies on WebViews with KaTeX/MathJax. I wanted a fully native alternative shared across all platforms. Pipeline:LaTeX → AST → TeX layout → DisplayList Layout is computed once in Rust, then natively rendered everywhere:iOS (CoreGraphics), Android (Canvas), Flutter, React Native, Web (WASM + Canvas) — no WebViews at all. I builded a “golden test” pipeline that compares ~1000 formulas against KaTeX using a simple ink-diff metric. It’s currently around ~0.9 similarity (higher for simpler layouts, lower for things like CD diagrams), support-table has the similarity score. Feature-wise, it covers most KaTeX-style math, and in practice handles a wider range of syntax than libraries like iosMath / SwiftMath — especially for mhchem-style expressions like \ce、\pu and CD diagrams. RaTeX is under active development. Found something wrong? Open an issue.
