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 13 August 2026; the live site may have changed since.

Numble is largely in shape, with a thorough launch checklist. Main gaps: no Permissions-Policy, incomplete legal pages, and no sitemap.

Launched on Product Hunt on August 13, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 4 months before launch. The crawl picked up 7 technologies on this site, covering analytics, CDN, DNS providers, and web fonts. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Web Analytics.

For context, it's on one of the most common stacks we track, shared by 594 launches and more locked down than the typical Product Hunt launch.
