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 April 2026; the live site may have changed since.

Coders.sh ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers and no email security records.

Launched on Product Hunt on April 21, 2026. The site is served through Cloudflare. We've detected 7 technologies on this site, covering CDN, CSS frameworks, DNS providers, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 3,879 other launches.
