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 22 August 2026; the live site may have changed since.
Seedance 2.5 looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.
Launched on Product Hunt on August 22, 2026. The site is hosted on Vercel, with a domain registered 4 months before launch. We've detected 25 technologies on this site, covering analytics, directory, javascript library, and ui library. The stack includes Google Sign-In, Next.js, and React.
It's running the same core stack as 13,761 other launches.
