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

Xylingo looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers.

Launched on Product Hunt on June 30, 2026. The site is hosted on Vercel, with a domain registered 3 months before launch. We've detected 10 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Svelte, SvelteKit, and Tailwind CSS.

It's one of just 7 launches we've crawled on this exact stack.
