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 20 April 2026; the live site may have changed since.

Youtube Thumbnail Downloader covers some of the launch checklist, with complete legal pages and a thorough launch checklist. Worth fixing first: missing several security headers, no robots.txt or sitemap, and tracking cookies set before any opt-in.

Launched on Product Hunt on April 20, 2026. The site is hosted on Vercel, with a domain registered the day of launch. Our crawler found 7 technologies on this site, covering advertising, analytics, DNS providers, and hosting. The stack includes Cloudflare DNS, Google Ads, and Google AdSense.

It's also running the same core stack as 2,955 other launches.
