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 18 August 2026; the live site may have changed since.
AvailEngine is largely in shape, with a thorough launch checklist and clean crawl signals. Visible gaps: no Permissions-Policy, incomplete legal pages, and incomplete email security.
Launched on PeerPush on August 18, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered 9 weeks before launch. The crawl picked up 8 technologies on this site, covering servers, baas, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Caddy, and Google Fonts.
For context, it's on one of the most common stacks we track, shared by 7,093 launches and more locked down than the typical PeerPush launch.
