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 13 August 2026; the live site may have changed since.
TestSlot is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.
Launched on Product Hunt on August 13, 2026. The site is hosted on Firebase App Hosting. The crawl picked up 8 technologies on this site, covering hosting, CSS frameworks, DNS providers, and business email. The stack includes Next.js, Tailwind CSS, and Envoy.
For context, it's running a stack combination we've seen on no other launch.
