# Introduction

> Welcome to PDFDyno - The fastest serverless PDF generation API.

## 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](https://typst.app/), a lightning-fast, Rust-based typesetting system.
