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

Web Vulnerability Scanner is early-stage. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 12, 2026. The site is hosted on Render in the United States. We've detected 3 technologies on this site, covering CDN, hosting, and protocol. The stack includes Cloudflare, HTTP/3, and Render.

It's on one of the most common stacks we track, shared by 158 launches.
