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 17 August 2026; the live site may have changed since.

Sokoban AI Solver is partway there, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on August 17, 2026. The site is hosted on GitHub Pages and served through Cloudflare. The crawl picked up 6 technologies on this site, covering CDN, DNS providers, business email, and hosting. The stack includes Cloudflare, Cloudflare DNS, and Fastly.

For context, it's on one of the most common stacks we track, shared by 2,329 launches.
