Own this Launch?

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

knowledge explorer still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on April 6, 2026. The site is hosted on Vercel and served through Cloudflare. The crawl picked up 10 technologies on this site, covering security, analytics, auth, and CDN. The stack includes Clerk, Cloudflare, and Cloudflare Bot Management.

For context, it's on one of the most common stacks we track, shared by 2,956 launches.
