Own this Launch?

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

Fastsleep.app (Dark UI) is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on April 12, 2026. The domain was registered 6 weeks before launch. Our crawler found 5 technologies on this site, covering business email, developer tools, DNS providers, and servers. The stack includes Jellyfish Cloud Email, LiteSpeed Web Server, and Namecheap DNS.
