pdfrender vs DocRaptor
DocRaptor is the hosted API for the commercial Prince engine — the print-CSS gold standard; pdfrender offers the same CSS Paged Media model for less.

| pdfrender | hosted HTML→PDF API on WeasyPrint — the open-source CSS Paged Media engine |
These are the two most alike products in this series: both render
with dedicated print engines (not a headless browser), both speak CSS Paged
Media — @page, margin boxes, page counters — and both meter by document
volume. DocRaptor fronts Prince, a long-established commercial engine;
pdfrender fronts WeasyPrint, the leading open-source implementation of the
same specs.
When DocRaptor is the better fit
- You need Prince-specific capabilities — its PDF/A and accessibility (tagged-PDF) output and its very deep paged-media feature set are ahead of any open-source engine.
- Enterprise document pipelines where the Prince engine is already the standard you validate against.
When pdfrender fits
- The same print-CSS authoring model (headers/footers, page sizes) at a lower, simpler price: free 100/month, €20/mo for 10,000, €80/mo for 100,000.
- Portability: WeasyPrint is open source, so documents you author against pdfrender render identically on a WeasyPrint you run yourself — no engine lock-in.
- Built-in MCP server for agent workflows.

FAQ
- Is WeasyPrint as good as Prince?
- For the CSS Paged Media model both implement — @page, margin boxes, page counters — the authoring experience is close. Prince is ahead on PDF/A and tagged-PDF accessibility output and on the depth of its paged-media feature set.
- Does pdfrender produce PDF/A or tagged accessible PDFs?
- No. If archival PDF/A or tagged accessibility output is a requirement, DocRaptor on the Prince engine is the correct choice.
- Will my documents still work if I stop using pdfrender?
- Yes. WeasyPrint is open source, so HTML and CSS authored against pdfrender render the same on a WeasyPrint instance you run yourself. There is no engine lock-in.
