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 28 April 2026; the live site may have changed since.
OpenLens looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on April 28, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered in 2013. We've detected 16 technologies on this site, covering analytics, business email, advertising, and auth. The stack includes Clerk, Next.js, and React.
It's running the same core stack as 432 other launches.
