With DocRaptor, users can create PDF and Excel documents from simple HTML. You send html to our server though the DocRaptor ruby gem, and you’ll get back a PDF or XLS file, all without having to deal with any awkward libraries or tedious coding. It’s document generation made easy.
Additionally, for HTML to PDF conversions, DocRaptor uses PrinceXML, allowing you all the options and features of this powerful tool, including great CSS2 support.
Plans start with a free option and increase depending on how many documents you need a month. Additional API documentation and examples can be found on the DocRaptor website.
Only took a few minutes to get rolling, sure beats setting up wkhtmltopdf on Heroku.
