  • Ask HN: What are you working on? (June 2026)
    I’m working on PDFBolt, a PDF generation API for developers. https://pdfbolt.com It’s for the boring pdf jobs every SaaS eventually gets: invoices, reports, certificates, contracts, labels, that kind of thing. You send html, a url, or a template with JSON data, and get a PDF back. Last week we shipped the Node SDK. Right now I’m working on the Python SDK and tightening up the docs. - Source: Hacker News / 3 months ago

  • Ask HN: What Are You Working On? (February 2026)

Most of my time lately goes into print production - browsers render everything in RGB but print needs CMYK with ICC color profiles, and getting that conversion right inside the PDF turned out to be a much deeper problem than expected. Got PDF/X-1a and PDF/X-4 working now. - Source: Hacker News / 7 months ago
  • Open source and self hostable/private file converter
    I can recommend https://pdfbolt.com. It is unfortunately not self-hosted but built with privacy in mind. I'm the founder. - Source: Hacker News / over 1 year ago
