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.
CleanSignups has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers, tracking cookies set before any opt-in, and no email security records.
Launched on Product Hunt on July 1, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 9 months before launch. Our crawler found 17 technologies on this site, covering analytics, security, ui library, and CDN. The stack includes Tailwind CSS, Cloudflare, and Cloudflare Bot Management.
It's also running the same core stack as 2,167 other launches.
