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 22 August 2026; the live site may have changed since.

Sara — AI School Tutor is partway there, with complete legal pages. What needs work: missing Permissions-Policy and Content-Security-Policy, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on August 22, 2026. The site is hosted on OVH SAS in France, with a domain registered in 2025. The crawl picked up 5 technologies on this site, covering developer tools, javascript library, os, and security. The stack includes Apache, HSTS, and React Router.

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