The problem

Still launching Chrome to make a PDF?

Puppeteer spins up a whole headless browser for every document. That's slow, heavy, and fragile — especially on serverless and edge runtimes.

Cold starts before you render

Just launching Chromium takes 300–800ms before it can even begin drawing your page — a non-starter for fast APIs and edge functions.

Memory-hungry and crashy

A single render can blow past 500MB of RAM, and long or image-heavy documents routinely trigger “Page crashed” errors.

Won't run on the edge

You can't ship Chromium to Cloudflare Workers or Vercel Edge. Teams end up maintaining a separate render service just for PDFs.

Breaks on the next update

A Chromium bump or a stray CSS change can silently shift your layout, sending you back to debugging a browser you never wanted to run.

Forme is a real PDF engine — no browser involved. Predictable output, milliseconds per render, and it deploys anywhere JavaScript does.

Try it live

Edit the JSX below and watch the PDF render in real time. No sign-up, no server — everything runs in your browser.
