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

YT1s: YouTube video downloader is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers, analytics without a consent banner, and no email security records.

Launched on Product Hunt on June 10, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 4 months before launch. The crawl picked up 5 technologies on this site, covering analytics, CDN, DNS providers, and protocol. The stack includes Cloudflare, Cloudflare DNS, and Google Analytics.
