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 August 2026; the live site may have changed since.

Suikou AI scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: no Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on August 26, 2026. The site is served through Cloudflare, with a domain registered 3 months before launch. We've detected 17 technologies on this site, covering analytics, javascript library, ui library, and CDN. The stack includes Next.js, React, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 5,476 launches and more locked down than the typical Product Hunt launch.
