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

CaptionLab is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on July 17, 2026. The site is hosted on GitHub Pages and served through Cloudflare. Our crawler found 12 technologies on this site, covering analytics, CDN, advertising, and DNS providers. The stack includes Cloudflare, Cloudflare Bot Management, and Fastly.

It's also running the same core stack as 1,742 other launches.
