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

KostAI looks production-ready overall, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. Visible gaps: incomplete legal pages and no email security records.

Launched on Product Hunt on April 27, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. We've detected 4 technologies on this site, covering DNS providers, web fonts, hosting, and security. The stack includes Cloudflare DNS, Google Fonts, and HSTS.

It's on one of the most common stacks we track, shared by 2,960 launches and more locked down than the typical Product Hunt launch.
