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 8 May 2026; the live site may have changed since.

Perfect Circle ships with the basics, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on May 8, 2026. The site is served through Cloudflare, with a domain registered 12 weeks before launch. We've detected 8 technologies on this site, covering analytics, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

It's on one of the most common stacks we track, shared by 7,385 launches.
