Faultsense

Show HN: Turn E2E tests into observability signals

Developer Tools

Added May 8, 2026 · Last analysed May 8, 2026 · via Hacker News

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 8 May 2026; the live site may have changed since.

Faultsense is largely in shape, with fast page loads and clean crawl signals. What needs work: no Permissions-Policy, incomplete legal pages, and incomplete email security.

Launched on Hacker News on May 8, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered in 2024. The crawl picked up 11 technologies on this site, covering CDN, CSS frameworks, DNS providers, and business email. The stack includes htmx, Tailwind CSS, and Cloudflare.

For context, it's on a stack we've seen on only 4 launches and tighter on security headers than most Hacker News launches.

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.
