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 8 May 2026; the live site may have changed since.

Airplane AI covers some of the launch checklist, with a thorough launch checklist and fast page loads. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on May 8, 2026. The site is served through Cloudflare, with a domain registered in 2023. Our crawler found 3 technologies on this site, covering analytics, CDN, and protocol. The stack includes Cloudflare, Cloudflare Web Analytics, and HTTP/3.
