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

Proofoo still has work before launch. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 15, 2026. The site is hosted on Fly.io in the United States. The crawl picked up 9 technologies on this site, covering analytics, build tooling, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Vite, and Fly.io.

For context, it's on a stack we've seen on only 23 launches.
