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 May 2026; the live site may have changed since.

Codebook of 450k+ unique words and phrases acts as a text compressor ships with the basics, with complete legal pages and fast page loads. Visible gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Hacker News on May 10, 2026. The site is hosted on GTHost in the United States. We've detected 2 technologies on this site, covering advertising and servers. The stack includes AdSkeeper and nginx.
