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 8 June 2026; the live site may have changed since.
KoalaSync 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 Product Hunt on June 8, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered 3 weeks before launch. The crawl picked up 2 technologies on this site, covering protocol and security. The stack includes HSTS and HTTP/3.
For context, it's tighter on security headers than most Product Hunt launches.
