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

Luston.ai ❤️ is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on June 10, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered 9 weeks before launch. The crawl picked up 9 technologies on this site, covering analytics, DNS providers, business email, and transactional email. The stack includes Next.js, React, and Cloudflare DNS.

For context, it's on one of the most common stacks we track, shared by 411 launches.
