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 21 June 2026; the live site may have changed since.
FixedHook covers some of the launch checklist, with complete legal pages. Main gaps: missing several security headers, no robots.txt or sitemap, and no email security records.
Launched on Product Hunt on June 21, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 3 weeks before launch. Our crawler found 9 technologies on this site, covering security, auth, CDN, and CSS frameworks. The stack includes Clerk, Next.js, and React.
Notably, it's on one of the most common stacks we track, shared by 8,078 launches.
