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 30 June 2026; the live site may have changed since.
Crossdeck scores highly overall, with complete legal pages and clean crawl signals. Main gaps: no Content-Security-Policy and incomplete email security.
Launched on Product Hunt on June 30, 2026. The site is hosted on Firebase App Hosting and served through Cloudflare, with a domain registered 7 weeks before launch. We've detected 9 technologies on this site, covering baas, CDN, DNS providers, and email forwarding. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.
It's one of just 3 launches we've crawled on this exact stack and more locked down than the typical Product Hunt launch.
