However, Prince comes with a hefty price tag for commercial usage. And if you need high-volume PDF generation, just maintaining your infrastructure can be a time-consuming chore. While Prince simplified document generation with its singular focus on PDFs, Prince does not perfectly mimic browser environments, leading to potential differences in rendering. This list of Prince XML alternatives has an option for every document and budget.
DocRaptor is an official Prince partner. We think Prince is the best PDF converter and DocRaptor is the best Prince XML alternative. We simply offer Prince as a SaaS API, instead of a standalone PDF converter library. DocRaptor has a free plan and our paid plans start at $15/month. We have API clients in Java, PHP, Ruby, Python, and more.
As an API-based tool, there's no need to manage additional infrastructure. You get instant scalability and reliability backed by our uptime guarantee and SOC2 compliance. You can be up and running in minutes with agents for all the popular languages and our no-signup development testing key.
In summary, WeasyPrint is the closest open-source alternative and free alternative to Prince's capabilities, but it may struggle with more complex files.
Chrome's PDF rendering capabilities are also the weakest on this list. Chrome will struggle with PDFs containing headers/footers, varying page sizes or layouts, forms, or requiring accessibility compliance. It's best for simple HTML documents.
These libraries are no longer being supported or developed. They rely on heavily outdated versions of the Webkit browser. While they were extremely popular years ago, and many other HTML to PDF libraries still rely on them, we strongly advise against using them. The other tools on this list will create higher-quality PDFs with faster development time. We mention them only to warn against using them.
When comparing HTML to PDF converters, focus on the most complex part of your document first. This will provide the fastest insight into whether or not the current tool will meet your needs. Consider your scalability requirements (how many concurrent PDFs do you need to generate?) and development capacity (will you ultimately save money with a more flexible commercial solution?) as well.
While Prince XML offers powerful HTML to PDF functionality, each alternative has its own strengths and weaknesses. Your selection between them hinges on your project's requirements and budget, and your technical capacity. We believe DocRaptor offers the best balance of capability and budget, but the choice is yours!
