Canary Watch

Monitors your deployed URLs after pushes to catch regressions you'd otherwise miss until a user complains. Checks HTTP status, console errors, network failures, performance metrics like LCP and CLS, SSE stream health, and static asset integrity. Run it once for a quick smoke test or set it to loop every few minutes during a launch window. The baseline comparison is smart: it only alerts on new console errors and performance deltas, not every warning your app already had. Honestly most useful when you've just deployed something risky and want to walk away confident, or when you need sustained monitoring during a critical release window. Beats refreshing the browser and checking DevTools manually.
