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

Purr has the basics covered well, with complete legal pages and a thorough launch checklist. Main gaps: no Content-Security-Policy, no robots.txt or sitemap, and incomplete email security.

Launched on Hacker News on June 25, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2015. Our crawler found 2 technologies on this site, covering hosting and security. The stack includes HSTS and Netlify.

Notably, it's on one of the most common stacks we track, shared by 1,274 launches and more locked down than the typical Hacker News launch.
