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 26 April 2026; the live site may have changed since.

crossword.training still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on April 26, 2026. The site is hosted on Vercel, with a domain registered 2 days before launch. The crawl picked up 7 technologies on this site, covering analytics, CSS frameworks, DNS providers, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 10,672 launches.
