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 30 June 2026; the live site may have changed since.
ColorBook Studio is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, no robots.txt, and incomplete email security.
Launched on Product Hunt on June 30, 2026. The site is served through Cloudflare, with a domain registered 1 day before launch. The crawl picked up 8 technologies on this site, covering CDN, DNS providers, email forwarding, and transactional email. The stack includes cdnjs, Cloudflare, and Cloudflare DNS.
