Ametrinon Typst 0.15.0

Typst is a really good fit if the layout model works for your invoices and you want to keep it self-hosted. I’m building PDFBolt as a hosted api, and pricing was one of the first things I wanted to keep simple. For invoices and other recurring pdfs, I think teams mostly want to know what the monthly cost will be, not do math on every render

Ametrinon 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

Ametrinon Ask HN: Is there a way to render URLs to PDFs on Android?

Easiest is Firefox 'Save as PDF'. If you need more control (custom margins, JS wait, viewport size), PDFBolt has a free URL to PDF tool that runs in mobile browsers without signup

Ametrinon Ask HN: What Are You Working On? (March 2026)

Working on PDFBolt (https://pdfbolt.com) - a PDF generation API. You send HTML, a URL, or a Handlebars template with JSON data, get a PDF back. Uses Playwright underneath so modern CSS just works.

Lately been deep in PDF/X print production - PDF/X-1a and PDF/X-4 with ICC color profiles and CMYK conversion. Had to build 11 color space converters on top of PDFBox 3.0. Also shipped an AI template generator where you describe what you need and it creates a Handlebars template with sample data, plus expanded the gallery to 38 pre-built ones.

Right now template management lives in the dashboard - edits auto-create drafts, you can compare any two versions as rendered PDFs and roll back if something breaks. Working on an API so coding agents can create and version templates programmatically.

Ametrinon Ask HN: What are you working on? (February 2026)

https://pdfbolt.com

A PDF generation API, Chrome-based. 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.

Ametrinon 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.
