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 1 August 2026; the live site may have changed since.

Errors ships with the basics, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on August 1, 2026. The site is served through Cloudflare, with a domain registered in 2012. We've detected 2 technologies on this site, covering CDN and DNS providers. The stack includes Cloudflare and Cloudflare DNS.
