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 July 2026; the live site may have changed since.

EnglishGPT ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: no Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on July 23, 2026. The site is hosted on Fly.io and served through Cloudflare. Our crawler found 19 technologies on this site, covering hosting, package cdn, security, and analytics. The stack includes Tailwind CSS, Caddy, and Cloudflare.

It's also running a stack combination we've seen on no other launch and tighter on security headers than most Product Hunt launches.
