iText VS gotenberg

Are you looking for a way to render PDF's or produce them? If you want to produce PDF's, I've used https://pdfbox.apache.org/ successfully as well as https://itextpdf.com/ (potentially costs money).

So, the case study would be an optional request/collaboration, but slapping your logo on their site (as seen on their home page just below the fold) is not written as optional. Say what you will about AGPL, but if you're a paying customer, this should be an easy provision to strike from the agreement if requested. They declined and our internal legal team refused to accept the agreement as a result and so we found a different provider.

Not really a JavaFX question as JavaFX is a UI framework. Your question is therefore just related to Java. To answer that I've seen a similar feature from IText (https://itextpdf.com) or OpenPDF (https://github.com/LibrePDF/OpenPDF) as an open source alternative. Maybe take a look at those for a start and check if they provide you what you're looking for.

Use a server-side headless browser such as puppeteer to convert the HTML to PDF. This is the most reliable free option, but requires a server. If you need to use it in production, we recommend you use Gotenberg.

We're using Gotenberg[1] to convert a rendered web page (with Elixir/Phoenix, in our case) to PDF. Works like a charm and we can use our existing frontend code/styling (including SVG graph generators) which is a huge bonus.

If you also want to convert Markdown or LibreOffice formats, the self-hosted API Gotenberg is worth checking out

I found a project that does exactly that (https://github.com/gotenberg/gotenberg). It’s my best bet for now, but I still need to test GraalVM integration with JS runtimes (and test JS libraries) and the Kotlin compiler targeting Node.

Gotenberg is a Docker-based stateless API for PDF generation from HTML and Markdown files.
