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 6 June 2026; the live site may have changed since.

LightShadow: 16-bit Photo Resizer still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 6, 2026. The site is hosted on IDC in China, with a domain registered in 2020. The crawl picked up 5 technologies on this site, covering analytics, cloud, DNS providers, and frameworks. The stack includes jQuery, Alibaba Cloud, and Baidu Tongji.

For context, it's running the same core stack as 115 other launches.
