\compare{vs-overleaf}
Overleaf is a great collaborative editor. But it has no public REST API for programmatic compilation. FormaTeX is built specifically for developers who need to automate LaTeX to PDF from code.
Overleaf is a browser-based collaborative LaTeX editor. It has no publicly documented REST API for compiling documents programmatically. You cannot call Overleaf from your backend, your CI pipeline, or any automated workflow.
If you need to generate PDFs from LaTeX without human interaction — from a script, a webhook, or a backend service — Overleaf is simply not the right tool.
FormaTeX exposes a single POST /v1/compile/sync endpoint. Send your .tex source and receive a compiled PDF in seconds — from any language, any server, any pipeline.
It supports pdflatex, xelatex, lualatex, and latexmk. The managed infrastructure means you pay only for compilations — not for idle compute or browser seats.

\section{Decision Guide}
Choose FormaTeX when…
Choose Overleaf when…
Generate hundreds of personalised PDF certificates from a script or webhook. Overleaf requires a human to open and compile each document — FormaTeX does it in one API call.
Compile LaTeX documentation or reports on every git push. FormaTeX integrates with GitHub Actions, GitLab CI, and any HTTP-capable pipeline. Overleaf has no CI integration.
Expose a PDF download endpoint from your Rails, Django, or Express app. Call FormaTeX server-side and stream the PDF to users — no browser, no Overleaf account required.
