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

hnsubstacks is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on July 7, 2026. The site is served through Cloudflare, with a domain registered 2 days before launch. Our crawler found 5 technologies on this site, covering analytics, CDN, developer tools, and DNS providers. The stack includes Svelte, Cloudflare, and Cloudflare DNS.

It's also one of 33 launches on this exact stack.
