Rendering images on the server without a headless browser
Why we replaced Chrome-based screenshotting with Satori, and what it costs you in CSS support.
Engineering notes
Short write-ups of problems we hit while building our own products. No tutorials, no thought leadership – just the reasoning behind decisions we had to live with afterwards.
Design tokens as a contract between the client and the renderer
One source of truth for colour and type across a React Native app and a Node rendering service – enforced by CI, not by discipline.
Fetching a URL the user gave you
SSRF hides in the redirect chain, not in the first request. Three fixes we shipped to our link importer.
The boring CI checks that keep paying off
Dependency licences, theme tokens and a type check – three cheap gates that catch more than our test suite does.
