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

Gravity ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing Permissions-Policy and Content-Security-Policy and incomplete email security.

Launched on Product Hunt on June 19, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 5 weeks before launch. The crawl picked up 9 technologies on this site, covering business email, CDN, DNS providers, and transactional email. The stack includes Cloudflare, Cloudflare DNS, and Google Fonts.

For context, it's tighter on security headers than most Product Hunt launches.
