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 28 June 2026; the live site may have changed since.

SignalStac is partway there, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers, no sitemap, and incomplete email security.

Launched on Product Hunt on June 28, 2026. The site is hosted on Cloudflare in the United States. The crawl picked up 8 technologies on this site, covering analytics, CDN, DNS providers, and email forwarding. The stack includes Next.js, React, and Cloudflare.

For context, it's running the same core stack as 568 other launches.
