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 23 July 2026; the live site may have changed since.

CobaltCode looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers.

Launched on Hacker News on July 23, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch. We've detected 14 technologies on this site, covering analytics, CDN, consent tooling, and CSS frameworks. The stack includes Astro, Google, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 511 launches.
