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 June 2026; the live site may have changed since.

ZeroFS still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on June 11, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 11 months before launch. The crawl picked up 8 technologies on this site, covering security, DNS providers, business email, and web fonts. The stack includes Cloudflare DNS, Fastmail, and Google Fonts.

For context, it's on one of the most common stacks we track, shared by 1,283 launches.
