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

PixelUp is missing several launch fundamentals. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on July 18, 2026. The site is hosted on Alibaba (US) Technology Co. in the United States. Our crawler found 10 technologies on this site, covering analytics, servers, advertising, and DNS providers. The stack includes Alibaba Cloud, Alibaba Mail, and Apache.
