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 July 2026; the live site may have changed since.

Cosm is partway there, with a thorough launch checklist and fast page loads. What needs work: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on July 21, 2026. The site is served through Cloudflare, with a domain registered 3 months before launch. The crawl picked up 4 technologies on this site, covering CDN, transactional email, web fonts, and protocol. The stack includes Cloudflare, Google Fonts, and HTTP/3.
