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

TUNL - Cave Flyer ships with the launch fundamentals in place, with a complete set of security headers, a thorough launch checklist, and well-configured email security. What needs work: incomplete legal pages.

Launched on PeerPush on August 21, 2026. The site is hosted on Zettaplan AG in Switzerland. We've detected 4 technologies on this site, covering DNS providers, business email, security, and servers. The stack includes Hostfactory, HSTS, and Microsoft IIS.

It's tighter on security headers than most PeerPush launches.
