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 13 May 2026; the live site may have changed since.

Qlavist has the basics covered well, with complete legal pages and fast page loads. Worth fixing first: no Permissions-Policy, no sitemap, and incomplete email security.

Launched on PeerPush on May 13, 2026. The site is hosted on DigitalOcean App Platform and served through Cloudflare, with a domain registered in 2023. Our crawler found 24 technologies on this site, covering CSS frameworks, javascript library, security, and advertising. The stack includes Bootstrap, Google Sign-In, and Tailwind CSS.

It's also on a stack we've seen on only 2 launches and tighter on security headers than most PeerPush launches.
