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

Passo ships with the basics. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt.

Launched on Hacker News on April 26, 2026. The site is hosted on Netlify, with a domain registered in 2020. We've detected 4 technologies on this site, covering DNS providers, hosting, security, and seo. The stack includes Google Search Console, HSTS, and Netlify.

It's running the same core stack as 1,570 other launches.
