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 22 June 2026; the live site may have changed since.

Skillably scores well across the board, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 22, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 9 months before launch. Our crawler found 14 technologies on this site, covering analytics, CDN, security, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's on one of the most common stacks we track, shared by 2,872 launches.
