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

VyvyManga is partway there, with clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 13, 2026. The site is served through Cloudflare. The crawl picked up 7 technologies on this site, covering advertising, analytics, CDN, and DNS providers. The stack includes Next.js, React, and Adsco.re.

For context, it's running the same core stack as 704 other launches.
