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 10 August 2026; the live site may have changed since.
Idle9 — Persistent dev environments for AI coding scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: incomplete email security.
The site is served through Cloudflare, with a domain registered 4 weeks before launch. The crawl picked up 13 technologies on this site, covering security, auth, captcha, and CDN. The stack includes Clerk, Caddy, and Cloudflare.
For context, it's more locked down than the typical StackScope Discovery launch.
