Doppio
Doppio is an API that turns HTML into pixel-perfect PDFs and screenshots using managed Chromium rendering. · Doppio · Compute
Overview
Doppio is an HTML-to-PDF and screenshot API, powered by managed Chromium, with direct S3 upload and webhook support. The free Basic plan renders up to 400 documents a month with 1 template and no credit card required — enough for small projects — with paid plans available for higher volume, more templates, and async rendering.
Good fit
Use Doppio when you need an API to turn HTML into PDFs or screenshots without running your own Chromium infrastructure.
- developers generating invoices or reports
- screenshot and document workflows
- indie hackers
Not a fit
Avoid if you need more than 400 documents a month, more than 1 template, or async rendering — these require a paid plan.
- need high document volume
- need multiple templates
- need async rendering
