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

Edsger is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on June 2, 2026. The site is hosted on AS12876 - Scaleway SAS in France, with a domain registered in 2009. Our crawler found 5 technologies on this site, covering DNS providers, business email, os, and seo. The stack includes Google Search Console, home.pl, and home.pl Email.
