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 16 June 2026; the live site may have changed since.
Caption Room scores well across the board, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: no Content-Security-Policy, incomplete legal pages, and no email security records.
Launched on Product Hunt on June 16, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 1 week before launch. The crawl picked up 12 technologies on this site, covering auth, analytics, captcha, and CDN. The stack includes Auth.js, Google Sign-In, and Next.js.
For context, it's on one of the most common stacks we track, shared by 2,642 launches and more locked down than the typical Product Hunt launch.
