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

TeenCycle has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on June 28, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 5 weeks before launch. Our crawler found 9 technologies on this site, covering analytics, DNS providers, business email, and hosting. The stack includes Cloudflare DNS, Google Analytics, and Google Search Console.

Notably, it's on one of the most common stacks we track, shared by 2,362 launches.
