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

Classer is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.

Launched on Hacker News on June 11, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 4 months before launch. The crawl picked up 12 technologies on this site, covering cloud, auth, CDN, and CSS frameworks. The stack includes Auth.js, Next.js, and React.

For context, it's running the same core stack as 480 other launches.
