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.
Proof of Usefulness is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on July 7, 2026. The site is hosted on Vercel, with a domain registered 10 months before launch. The crawl picked up 10 technologies on this site, covering analytics, backend framework, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Cloudflare DNS, and Express.
For context, it's running the same core stack as 2,272 other launches.
