Tex Leaf

Local-first web LaTeX editor with browser UI and native pdfTeX compilation.

I kept running into the same problem with online LaTeX editors—they're either underpowered or they ship your data to some cloud server. Tex Leaf keeps everything local: Monaco editor with full syntax highlighting, a PDF.js viewer for instant preview, and native pdfTeX compilation through Go on the backend. No accounts, no cloud sync, just open the browser and write.

On the backend, Go handles PDF compilation using pdftex for proper LaTeX rendering rather than a JavaScript approximation. Docker support is available for self-hosting, and the editor fills the gap between heavyweight desktop tools and underpowered online alternatives.
