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 12 May 2026; the live site may have changed since.

Hopper ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: tracking cookies set before any opt-in.

Launched on Product Hunt on May 12, 2026. The site is hosted on Vercel, with a domain registered in 2025. The crawl picked up 15 technologies on this site, covering analytics, CMS, collaboration, and CSS frameworks. The stack includes Next.js, React, and Sanity.

For context, it's one of 48 launches on this exact stack and tighter on security headers than most Product Hunt launches.
