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

Sleep Cycle By Age is partway there, with a thorough launch checklist, well-configured email security, and fast page loads. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 16, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 5 months before launch. The crawl picked up 6 technologies on this site, covering CDN, DNS providers, business email, and web fonts. The stack includes Cloudflare, Cloudflare DNS, and Google Fonts.
