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

Langusta is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers and incomplete email security.

Launched on Hacker News on June 16, 2026. The site is hosted on Google LLC in the United States. The crawl picked up 9 technologies on this site, covering servers, build tooling, DNS providers, and business email. The stack includes Vite, Anycast DNS, and Brevo.

For context, it's running the same core stack as 773 other launches.
