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 18 July 2026; the live site may have changed since.

Yapp scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: no email security records.

Launched on Hacker News on July 18, 2026. The site is served through Cloudflare, with a domain registered 7 weeks before launch. We've detected 9 technologies on this site, covering analytics, auth, CDN, and DNS providers. The stack includes Google Sign-In, Cloudflare, and Cloudflare DNS.

It's more locked down than the typical Hacker News launch.
