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

Free AP Practice scores well across the board, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: incomplete email security.

Launched on Product Hunt on June 21, 2026. The site is hosted on Cloudflare in the United States. We've detected 14 technologies on this site, covering advertising, analytics, auth, and CDN. The stack includes Google Sign-In, SvelteKit, and Tailwind CSS.

It's one of 41 launches on this exact stack and more locked down than the typical Product Hunt launch.
