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 16 June 2026; the live site may have changed since.

Cpt-city, Xkcd colour schemes covers some of the launch checklist, with well-configured email security. Worth fixing first: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and no sitemap.

Launched on Hacker News on June 16, 2026. The site is hosted on Jisc Services Limited in the United Kingdom. Our crawler found 8 technologies on this site, covering build tooling, CSS frameworks, frameworks, and os. The stack includes Bootstrap, Rails, and Vite.

Notably, it's running a stack combination we've seen on no other launch and tighter on security headers than most Hacker News launches.
