Own this Launch?

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

zerodatatools is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on July 1, 2026. The site is hosted on GitHub Pages and served through Fastly. Our crawler found 10 technologies on this site, covering seo, analytics, CDN, and CSS frameworks. The stack includes Tailwind CSS, Bing Webmaster, and cdnjs.

It's also on one of the most common stacks we track, shared by 179 launches.
