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 10 April 2026; the live site may have changed since.

Mastery is early-stage. Visible gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on April 8, 2026. The site is served through Cloudflare, with a domain registered 2 days before launch. We've detected 6 technologies on this site, covering CDN, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

It's on one of the most common stacks we track, shared by 5,951 launches.
