Screenshot of Leafy — Vocabulary Builder for Mac

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.

Leafy — Vocabulary Builder for Mac ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: no Strict-Transport-Security and incomplete email security.

Launched on Product Hunt on July 4, 2026. The site is served through Cloudflare, with a domain registered 4 days before launch. We've detected 6 technologies on this site, covering CDN, DNS providers, email forwarding, and javascript library. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.

It's tighter on security headers than most Product Hunt launches.
