Own this Launch?

StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 28 April 2026; the live site may have changed since.

DevUtils covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on April 28, 2026. The site is hosted on O2SWITCH in France, with a domain registered in 2015. Our crawler found 3 technologies on this site, covering consent tooling, developer tools, and seo. The stack includes Google, Google Search Console, and Vite.
