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 26 April 2026; the live site may have changed since.

XInvoice is partway there, with complete legal pages and fast page loads. Worth fixing first: missing several security headers, no sitemap, and incomplete email security.

Launched on PeerPush on April 25, 2026. The site is hosted on HETZNER-AS in Germany, with a domain registered 2 weeks before launch. The crawl picked up 5 technologies on this site, covering CSS frameworks, developer tools, DNS providers, and os. The stack includes Tailwind CSS, Apache, and Debian.

For context, it's running the same core stack as 5,950 other launches.
