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 July 2026; the live site may have changed since.

Learnpg still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on July 19, 2026. The site is hosted on DigitalOcean in the United States. The crawl picked up 5 technologies on this site, covering developer tools, DNS providers, email forwarding, and protocol. The stack includes Caddy, HTTP/3, and Namecheap DNS.
