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

51视频网 scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on July 3, 2026. The site is served through Cloudflare, with a domain registered 2 weeks before launch. We've detected 8 technologies on this site, covering analytics, CDN, DNS providers, and frameworks. The stack includes Next.js, React, and Cloudflare.

It's on one of the most common stacks we track, shared by 628 launches.
