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 12 April 2026; the live site may have changed since.

Browserbeam ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Hacker News on April 1, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. Our crawler found 15 technologies on this site, covering analytics, CSS frameworks, backend framework, and CDN. The stack includes Bootstrap, Tailwind CSS, and Cloudflare.

It's also running the same core stack as 139 other launches and tighter on security headers than most Hacker News launches.
