LaTeXdiff Online
thelatexlab.com/latexdiff-online/ →Finally, latexdiff without the terminal
WHAT IT SOLVES
Every LaTeX user knows latexdiff — it marks up changes between two drafts, perfect for supervisors or journal submissions. But it requires Perl, a pile of dependencies, and the command line. Most people install it once, forget how, and Google the same tutorial next time
WHY IT'S INTERESTING
Upload entire project ZIPs
Real LaTeX projects aren't single files — you've got chapters/, figures/, .bib scattered everywhere. This tool accepts full .zip project uploads and diffs between two complete project directories. That one detail tells you the author has written a real thesis
Running Perl in the browser, actually
latexdiff is a Perl script. This runs it in the browser — no server-side Perl install, your files never leave your machine. Built with Claude Code. Reddit users apparently loved it; the HN title says so right there
「The HN title itself says 'Reddit users loved it' — dude's clearly proud of the reception」
TECH GUESS
Perl in the browser (likely WebPerl or WASM-compiled), frontend probably React or vanilla JS, hosted as a subpath on thelatexlab.com
