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 27 May 2026; the live site may have changed since.

YT-brief ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: no email security records.

Launched on Product Hunt on May 27, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 1 week before launch. The crawl picked up 12 technologies on this site, covering security, auth, CDN, and CSS frameworks. The stack includes Clerk, Next.js, and React.

For context, it's running the same core stack as 10,676 other launches and tighter on security headers than most Product Hunt launches.
