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

Read is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on April 20, 2026. The site is served through Cloudflare, with a domain registered in 2021. Our crawler found 4 technologies on this site, covering analytics, CDN, developer tools, and protocol. The stack includes Cloudflare, HTTP/3, and PostHog.
