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 27 April 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.

Freelance Developer Operating System has the basics covered well, with a thorough launch checklist and clean crawl signals. Visible gaps: no Permissions-Policy, incomplete legal pages, and no email security records.

Launched on Product Hunt on April 27, 2026. The site is served through Cloudflare. Our crawler found 54 technologies on this site, covering advertising, analytics, media handling, and social embeds. The stack includes Contentful, Google OAuth, and Google Sign-In.

It's also one of just 24 launches we've crawled on this exact stack and more locked down than the typical Product Hunt launch.
