Screenshot of Ad-Free Interval Timer

StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 26 May 2026; the live site may have changed since.

Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.

Ad-Free Interval Timer ships with the basics, with clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on May 26, 2026. The site is hosted on GitHub Pages and served through Cloudflare, with a domain registered 9 months before launch. We've detected 6 technologies on this site, covering CDN, web fonts, hosting, and package cdn. The stack includes cdnjs, Cloudflare, and Fastly.

It's running the same core stack as 2,669 other launches.
