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.
Deutsch Lernen is partway there, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on July 4, 2026. The site is hosted on Google Cloud, with a domain registered 3 weeks before launch. The crawl picked up 15 technologies on this site, covering advertising, AI builders, analytics, and APIs. The stack includes Clerk, Expo, and Svelte.
For context, it's one of only 31 launches we've crawled running Expo.
