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

VellumUp ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: tracking cookies set before any opt-in.

Launched on PeerPush on July 25, 2026. The site is hosted on Vercel, with a domain registered 3 months before launch. The crawl picked up 18 technologies on this site, covering analytics, ai api, AI builders, and baas. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 11,334 other launches and tighter on security headers than most PeerPush launches.
