daneden/basehold.it
A quick, painless, Javascript-free baseline overlay.
A hosted service that serves a baseline grid overlay as a pure CSS stylesheet or PNG image, parameterized by URL path. One link tag and you have a typographic baseline grid for development — no JavaScript, no npm install. It's a utility tool for designers and front-end developers doing typography work.
The URL API is genuinely clever — encoding grid size and color directly in the path means zero configuration and works in any static context. No JavaScript dependency is a real win; it works in environments that block scripts or where you just want something that can't break. The bookmarklet auto-detects body line-height via getComputedStyle, which is the one case where you'd actually want dynamic behavior. Hosted on Vercel so latency is low and you don't have to run anything.
This is a hosted third-party service in your critical CSS path — if basehold.it goes down, your dev build shows a network error on every page load. There's no self-hosting option documented, and the Next.js source being public doesn't make that obvious. The image-mode approach with background-image on html is fragile if you already have a background set. With 26 forks and last meaningful activity years ago, this is effectively unmaintained; the domain staying up is the only thing keeping it working.
