Get the same Chromium-grade rendering without the headless browser to babysit. IronPDF bundles its own engine, runs in three lines of C#, and adds full PDF editing on top. No Chromium download, no page pool, no X-server on Linux.

Install-Package IronPdf
PuppeteerSharp is a capable .NET port of Node Puppeteer, but it is browser automation first and PDF generation second. You download a Chromium build on first run, manage the browser and page lifecycle yourself, and build a page pool to survive load. IronPDF wraps a Chromium engine inside the NuGet package, exposes one synchronous render call, and adds editing, merging, forms, and signing in the same library.
| PuppeteerSharp | IronPDF | |
|---|---|---|
| Rendering engine | Headless Chromium, downloaded | Chromium bundled in the package |
| First-run setup | BrowserFetcher.DownloadAsync, 100MB+ | Install-Package, nothing to download |
| API style | Async browser and page lifecycle | One synchronous render call |
| Concurrency | Build your own browser / page pool | Thread-safe, built for servers |
| Linux and Docker | X-server and Chromium deps required | Runs headless, no X-server |
| PDF editing | Generate only | Edit, merge, stamp, sign, forms, compress |
| License and support | Free, open source, community | Commercial, perpetual license, 24/5 engineers |
Built for developers who want PuppeteerSharp-quality rendering without the browser to operate.

Where in the past we might have to go out and use one plug-in or one package for OCR, and another one for PDF, having them all integrated into one low-cost package was really great for us.
