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 August 2026; the live site may have changed since.

NexoChess scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: incomplete email security.

Launched on Product Hunt on August 25, 2026. The site is served through Cloudflare, with a domain registered 3 weeks before launch. We've detected 12 technologies on this site, covering advertising, analytics, CDN, and consent tooling. The stack includes Google Funding Choices, Brevo, and Cloudflare.

It's more locked down than the typical Product Hunt launch.
