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 July 2026; the live site may have changed since.
TheCaptionAI scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Content-Security-Policy and no email security records.
Launched on Product Hunt on July 28, 2026. The site is hosted on Vercel, with a domain registered 3 weeks before launch. Our crawler found 16 technologies on this site, covering analytics, email forwarding, advertising, 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 11,655 launches and more locked down than the typical Product Hunt launch.
