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

Three Red Boxes is missing several launch fundamentals. What needs work: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on PeerPush on June 11, 2026. The site is hosted on DigitalOcean in the United States, with a domain registered in 2023. Our crawler found 7 technologies on this site, covering DNS providers, business email, web fonts, and monitoring. The stack includes Cloudflare DNS, Clutch, and Google Fonts.
