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 25 May 2026; the live site may have changed since.

Kocteau looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and no email security records.

Launched on Product Hunt on May 25, 2026. The site is hosted on Vercel, with a domain registered 5 weeks before launch. We've detected 10 technologies on this site, covering audio, CSS frameworks, DNS providers, and transactional email. The stack includes Next.js, React, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 10,677 launches.
