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 August 2026; the live site may have changed since.

Skylens ships with the launch fundamentals in place, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. Worth fixing first: incomplete legal pages and incomplete email security.

Launched on Hacker News on August 23, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch. We've detected 11 technologies on this site, covering data api, analytics, CDN, and developer tools. The stack includes CelesTrak, Cloudflare, and Cloudflare Web Analytics.

It's tighter on security headers than most Hacker News launches.
