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 4 July 2026; the live site may have changed since.

Sonar ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing Permissions-Policy and Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on July 4, 2026. The site is hosted on Hostinger International Limited in Lithuania, with a domain registered 12 weeks before launch. The crawl picked up 7 technologies on this site, covering analytics, web fonts, os, and security. The stack includes Google Analytics, Google Fonts, and Google Tag Manager.

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