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

APIEval-20 ships with the basics, with a thorough launch checklist, fast page loads, and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on May 8, 2026. The site is served through Cloudflare, with a domain registered in 2022. We've detected 5 technologies on this site, covering analytics, CDN, web fonts, and protocol. The stack includes Cloudflare, Google Analytics, and Google Fonts.
