Introduction

Nebula PDF Engine is a high-performance, server-side PDF generation library that turns React/JSX templates into multi-page documents. You write familiar Flexbox-style layouts with Preact — without Headless Chrome — in a lightweight package that is typically orders of magnitude smaller than Puppeteer.

Powered by Satori, Resvg, and pdf-lib, Nebula gives you pixel-perfect layout control with the familiarity of Flexbox and JSX.

Ideal for generating dynamic invoices, automated business reports, and high-density shipping labels at the edge.
