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 2 June 2026; the live site may have changed since.

Primerpickr scores highly overall, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and incomplete email security.

Launched on Hacker News on June 2, 2026. The site is served through Cloudflare, with a domain registered 11 months before launch. We've detected 15 technologies on this site, covering package cdn, analytics, CDN, and CSS frameworks. The stack includes Alpine.js, Tailwind CSS, and cdnjs.

It's on one of the most common stacks we track, shared by 112 launches and more locked down than the typical Hacker News launch.
