Own this Launch?

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 28 July 2026; the live site may have changed since.

CheckCyber ships with the launch fundamentals in place, with a thorough launch checklist, well-configured email security, and clean crawl signals. What needs work: no Content-Security-Policy and incomplete legal pages.

Launched on Product Hunt on July 28, 2026. The site is hosted on O2SWITCH SAS in France, with a domain registered 7 weeks before launch. We've detected 9 technologies on this site, covering advertising, consent tooling, CSS frameworks, and DNS providers. The stack includes Gatekeeper, Svelte, and SvelteKit.
