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 June 2026; the live site may have changed since.

Beacon is partway there, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 23, 2026. The site is hosted on Cloudflare in the United States. The crawl picked up 15 technologies on this site, covering security, advertising, ai service, and CDN. The stack includes Tailwind CSS, Cloudflare, and Cloudflare Bot Management.

For context, it's running the same core stack as 2,022 other launches.
