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 24 June 2026; the live site may have changed since.

Seedance 2.5 is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 24, 2026. The site is hosted on Amazon.com in the United States. The crawl picked up 12 technologies on this site, covering analytics, auth, CSS frameworks, and DNS providers. The stack includes Clerk, Next.js, and React.

For context, it's on one of the most common stacks we track, shared by 8,457 launches.
