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

Opencomputer still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on June 23, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 4 days before launch. The crawl picked up 2 technologies on this site, covering CDN and protocol. The stack includes Cloudflare and HTTP/3.
