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

SteelSpine covers some of the launch checklist, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing several security headers, no sitemap, and incomplete email security.

Launched on Product Hunt on May 19, 2026. The site is served through Cloudflare, with a domain registered 7 weeks before launch. Our crawler found 5 technologies on this site, covering CDN, DNS providers, email forwarding, and media handling. The stack includes Asciinema, Cloudflare, and Cloudflare DNS.
