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 23 August 2026; the live site may have changed since.

React-comic-viewer is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on August 23, 2026. The site is hosted on Vercel. We've detected 5 technologies on this site, covering analytics, frameworks, hosting, and meta-frameworks. The stack includes Next.js, React, and HSTS.

It's running the same core stack as 3,133 other launches.
