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.
Respan 1.0 has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and tracking cookies set before any opt-in.
Launched on Product Hunt on April 28, 2026. The site is hosted on Vercel, with a domain registered 3 months before launch. Our crawler found 18 technologies on this site, covering advertising, analytics, seo, and auth. The stack includes Auth.js, Next.js, and React.
It's also on one of the most common stacks we track, shared by 10,662 launches.
