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 June 2026; the live site may have changed since.

Card 4 Share has the basics covered well, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on PeerPush on June 28, 2026. The site is hosted on Fastly in the United States, with a domain registered 10 months before launch. Our crawler found 12 technologies on this site, covering analytics, baas, CDN, and CSS frameworks. The stack includes Capacitor, Tailwind CSS, and Fastly.

Notably, it's a rare Capacitor sighting, just 33 in our data.
