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 28 July 2026; the live site may have changed since.

TOEFLPrepTest is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on July 28, 2026. The site is hosted on Vercel, with a domain registered 3 days before launch. The crawl picked up 10 technologies on this site, covering analytics, CSS frameworks, DNS providers, and transactional email. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 11,751 other launches.
