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 7 July 2026; the live site may have changed since.

Seedance 2.5 has the basics covered well, 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 July 7, 2026. The site is served through Cloudflare. Our crawler found 24 technologies on this site, covering directory, javascript library, analytics, and CDN. The stack includes Tailwind CSS, TanStack Start, and AIDirs.

It's also running the same core stack as 215 other launches.
