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 9 July 2026; the live site may have changed since.
Fiz scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Content-Security-Policy and incomplete email security.
Launched on Product Hunt on July 9, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch. We've detected 9 technologies on this site, covering captcha, CDN, directory, and DNS providers. The stack includes Svelte, Cloudflare, and Cloudflare DNS.
It's one of 36 launches on this exact stack and more locked down than the typical Product Hunt launch.
