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

Playcanvas and Gracia 4dgs still has work before launch. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on April 2, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2023. The crawl picked up 1 technology on this site, covering servers. The stack includes nginx.
