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 August 2026; the live site may have changed since.
404leads is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.
Launched on Product Hunt on August 12, 2026. The site is served through Cloudflare, with a domain registered 3 months before launch. The crawl picked up 11 technologies on this site, covering ui library, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, TanStack Start, and Cloudflare.
For context, it's on one of the most common stacks we track, shared by 928 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.
