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 4 July 2026; the live site may have changed since.
Capo by Sonid is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.
Launched on Product Hunt on July 4, 2026. The site is hosted on Plesk and served through Cloudflare, with a domain registered in 2019. The crawl picked up 11 technologies on this site, covering analytics, ui library, CDN, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.
For context, it's on a stack we've seen on only 11 launches.
