DocRaptor is an HTML to PDF API. It prints with Prince, a typesetting engine built for print, and it's the only hosted API that does, by its own account. Printmint prints with Chromium, the engine behind Chrome. Which suits you depends mostly on that.

Choose DocRaptor if
- You rely on Prince. It's a print typesetting engine, and documents designed for it may not lay out the same in a browser engine.
- You want to try without an account: its public test key makes watermarked documents for free.
- You want it to host the finished documents for you, which it offers per document.
Choose Printmint if
- Your HTML is already designed for Chrome, so the PDF looks like the page.
- You'd rather send JSON than HTML: an invoice, receipt, certificate, report or label template is built in, and you can save your own.
- You print a lot. 3,000 documents a month is $10; 30,000 is $50.
- You want the same templates as images, or to merge PDFs, in the same API.
Moving over
Printmint takes the HTML you already send: POST /v1/pdf/render with html,
and pdf for the page size and margins. Headers and footers use Chromium's
templates (see the guide) rather
than CSS running elements, so check those pages first.
