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

YouTube Thumbnail Downloader is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on July 28, 2026. The site is hosted on Hostinger and served through Cloudflare, with a domain registered 4 months before launch. The crawl picked up 20 technologies on this site, covering wordpress plugin, analytics, seo, and CDN. The stack includes WordPress, Ahrefs, and Bing Webmaster.

For context, it's running the same core stack as 1,268 other launches.
