RaTeX: KaTeX-compatible LaTeX rendering engine in pure Rust

If you've ever tried embedding math formulas in a web app, you know: KaTeX is great, but it's tied to JavaScript. What if you want server-side rendering with blazing performance? Enter RaTeX — a LaTeX rendering engine written in pure Rust, fully compatible with KaTeX.

Why it matters:

  • Rust means safety and speed. No memory leaks, no surprises — just clean, fast code.
  • KaTeX compatibility. If you already use KaTeX, migrating to RaTeX is nearly painless.
  • Server-side rendering. Generate formulas on the backend and serve ready HTML or SVG. Perfect for static sites, documentation, or scientific platforms.

Caveats? The project is young, the community is small, and documentation is still growing. But for experiments — it's a solid choice.

METABYTE studio comment: If your project needs fast and reliable math rendering, RaTeX is a great candidate. We can help integrate it into your architecture, whether it's a web app or a microservice.
