Why developers look for DocRaptor alternatives
DocRaptor is a solid product — it uses PrinceXML under the hood, which has excellent CSS support. But developers often look for alternatives because of:
- Price: $0.12/document adds up fast at scale
- Feature gaps: No document hosting, no signing, no templates
- No async processing: Every conversion is synchronous
- No batch API: Generating many documents requires sequential calls
Feature comparison
| Feature | pdfRelay | DocRaptor |
|---|---|---|
| Starting price | $29/mo (1,000 docs) | $15/mo (125 docs) |
| Cost per document | $0.029 | $0.12 |
| Document hosting | Included | No |
| E-signatures | Included | No |
| React templates | Yes | No |
| Batch processing | Up to 100/request | No |
| Async mode | Yes | No |
| Webhooks | 11 event types | No |
| Rendering engine | Custom Rust | PrinceXML (C++) |
The biggest difference isn't just features — it's the approach. DocRaptor requires you to learn PrinceXML's CSS extensions. pdfRelay uses standard HTML and CSS — the same code you'd write for a web page. No proprietary markup. No learning curve.
