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 29 May 2026; the live site may have changed since.
PlayByEar 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: incomplete email security.
Launched on Product Hunt on May 29, 2026. The site is hosted on Heroku and served through Cloudflare, with a domain registered 8 weeks before launch. The crawl picked up 17 technologies on this site, covering advertising, analytics, captcha, and CDN. The stack includes Google, Next.js, and React.
For context, it's on a stack we've seen on only 10 launches and tighter on security headers than most Product Hunt launches.
