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

Intelligrade is partway there, with complete legal pages. Main gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Hacker News on June 19, 2026. The site is hosted on Hetzner Online GmbH in Germany. The crawl picked up 9 technologies on this site, covering CSS frameworks, DNS providers, business email, and email marketing. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 2,753 launches.
