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 May 2026; the live site may have changed since.

VATValidation 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 May 18, 2026. The site is hosted on GitHub Pages and served through Fastly. Our crawler found 4 technologies on this site, covering CDN, web fonts, hosting, and static site generator. The stack includes Fastly, GitHub Pages, and Google Fonts.

It's also on one of the most common stacks we track, shared by 1,758 launches.
