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

HotFX Pseudorandom is partway there, with clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Hacker News on June 27, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2020. The crawl picked up 9 technologies on this site, covering analytics, javascript library, package cdn, and developer tools. The stack includes esm.sh, Hot Page, and HTTP/3.
