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

Varlog has the basics covered well, with a thorough launch checklist, fast page loads, and clean crawl signals. Worth fixing first: no Content-Security-Policy, incomplete legal pages, and incomplete email security.

Launched on Hacker News on April 11, 2026. The site is served through Cloudflare, with a domain registered in 2013. Our crawler found 7 technologies on this site, covering analytics, CDN, DNS providers, and business email. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Web Analytics.

It's also tighter on security headers than most Hacker News launches.
