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

Blog ships with the basics, with a thorough launch checklist, well-configured email security, and fast page loads. Worth fixing first: missing several security headers and incomplete legal pages.

Launched on Hacker News on June 22, 2026. The site is hosted on High5! B.V. in the Netherlands, with a domain registered in 2021. We've detected 3 technologies on this site, covering seo and hosting. The stack includes Bing Webmaster, Google Search Console, and SourceHut.
