BONNAURE Olivier
For years I struggled to find a truly fast and lightweight way to generate PDFs programmatically. Most tools out there are just HTML-to-PDF converters → bloated, slow, and resource-hungry. So I built my own PDF generation engine from scratch… in pure Lua. Result? → Thousands of PDFs per second on a single server → Sub-100 ms latency → Zero dependencies, tiny memory footprint → No user data ever stored (privacy by design) → 100% powered by renewable energy Then I thought: why keep this to myself? So I turned it into PDFx.fr - a blazing-fast PDF API made for developers who care about performance, privacy, and compliance. And yes - it natively supports Factur-X / ZUGFeRD invoices (fully compliant with EU regulations). If you’re tired of slow, bloated, or privacy-invasive PDF tools… come try the beta: https://pdfx.fr Feedback, ideas, or just want to chat about the project? DMs are open
