Why PDFDyno?

Generating PDFs in modern serverless environments (like Vercel, AWS Lambda, or Netlify) is notoriously painful. Traditional solutions rely on Puppeteer and Headless Chrome, which brings massive problems:
  • Cold Starts: Downloading and booting a 170MB browser binary takes up to 10 seconds.
  • Memory Leaks: Chrome frequently exceeds the strict RAM limits of serverless functions, causing hard crashes.
  • Data Privacy Risks: Many APIs store your generated PDFs on their servers, violating GDPR policies.
PDFDyno solves this. Instead of a heavy browser engine, PDFDyno runs on Typst, a lightning-fast, Rust-based typesetting system.

Blazing Fast

Compile complex documents in under 50 milliseconds. (Compare that to 50ms vs. 10s cold start with Puppeteer).

Zero Memory Crashes

Rust guarantees memory safety. Your functions will never crash from PDF generation again.

Zero Data Retention

We process your data in memory and delete it instantly. No S3 buckets, 100% GDPR compliant.

Developer Experience

A clean REST API. Just send JSON and your template. No messy UI builders.
