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 1 July 2026; the live site may have changed since.

Knock is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and no sitemap.

Launched on PeerPush on July 1, 2026. The site is hosted on Vercel, with a domain registered 3 months before launch. The crawl picked up 13 technologies on this site, covering javascript library, ui library, analytics, and CSS frameworks. The stack includes Tailwind CSS, Cloudflare DNS, and Cloudflare Email Routing.

For context, it's on one of the most common stacks we track, shared by 2,168 launches.
