Sentinel
Sentinel is an open-source AI QA agent that reads your repo, derives the real business flows, and tests them end to end across the frontend and the backend.
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 16 July 2026; the live site may have changed since.
Sentinel is early-stage. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt.
Launched on Hacker News on July 16, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered in 2020. We've detected 2 technologies on this site, covering publishing and servers. The stack includes Caddy and SlopIt.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
