This is the community's next iteration of the OpenHTMLtoPDF project.
Open HTML to PDF is a pure-Java library for rendering a reasonable subset of well-formed XML/XHTML (and even some HTML5) using CSS 2.1 (and later standards) for layout and formatting, outputting to PDF or images.
Use this library to generated nice looking PDF documents. But be aware that you can not throw modern HTML5+ at this engine and expect a great result. You must special craft the HTML document for this library and use it's extended CSS feature like #31 or #32 to get good results. Avoid floats near page breaks and use table layouts.

Thanks to @danfickle for his work advancing the OpenHtmlToPdf project beyond FlyingSaucer.
Open HTML to PDF is based on Flying-saucer. Credit goes to the contributors of that project. Code will also be used from neoFlyingSaucer
- OPEN HTML TO PDF is tested with Temurin 8, 11, 17 and 21. It requires at least Java 8 to run.
- No, you can not use it on Android.
- You should be able to use it on Google App Engine (Java 8 or greater environment). Let us know your experience.
Flowing columns are not implemented.Implemented in RC12.- No, it's not a web browser. Specifically, it does not run javascript or implement many modern standards such as flex and grid layout.
