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 16 July 2026; the live site may have changed since.

Deoit is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.

Launched on Product Hunt on July 16, 2026. The site is hosted on Vercel. The crawl picked up 7 technologies on this site, covering analytics, APIs, baas, and web fonts. The stack includes Firebase, Google APIs, and Google Fonts.

For context, it's running the same core stack as 2,902 other launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
