There's AntennaHouse and PrinceXML, but both are pretty pricey ($3-5K / server), and both of these do now support CSS as well.

Apache FOP / Batik is okay for generating nice looking PDFs, but its SVG rasterization is much worse than that of Chrome's PDF renderer (Skia).

As I didn't get the memo about XML being dead, I'm still using Docbook and XSLT/XInclude to structure and filter content written in markdown/rst.

But I will be switching over from XSL-FO to CSS paged media for layout as soon as Chrome supports bookmarks in PDF output, or either WeasyPrint or wkhtmltopdf improve their CSS3 column support.

Biased cause I work there, but DocRaptor offers a saas API version of the Prince library with a much lower usage-based monthly fee.
