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 1 July 2026; the live site may have changed since.
Clockjumper is largely in shape, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Hacker News on July 1, 2026. The site is served through Cloudflare, with a domain registered 7 months before launch. The crawl picked up 19 technologies on this site, covering analytics, security, ui library, and AI builders. The stack includes Tailwind CSS, TanStack Start, and Ahrefs.
For context, it's running the same core stack as 125 other launches.
