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

fossil ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: tracking cookies set before any opt-in and incomplete email security.

Launched on PeerPush on August 19, 2026. The site is hosted on Render and served through Cloudflare, with a domain registered 3 months before launch. We've detected 13 technologies on this site, covering ui library, analytics, CDN, and CSS frameworks. The stack includes Astro, Tailwind CSS, and Cloudflare.

It's on a stack we've seen on only 4 launches and tighter on security headers than most PeerPush launches.
