canary

You can monitor production deployments by pointing a canary monitor at the deployment URL to scan for console errors, performance regressions, and page failures. It compares live behavior against pre-deploy baselines to surface deviations.

Canary monitoring is the process of watching live application behavior after a deployment to catch issues early. You need it when you want to detect console errors, performance regressions, or page failures before customers notice them.

To catch visual regressions in production, you can use canary monitoring to take periodic screenshots and compare them against pre-deploy baselines. This surfaces visual deviations automatically during the post-deploy window.

Yes, you can run canary monitoring without external dependencies or components. You simply point the monitor at the new deployment URL and run it for ten minutes to begin collecting health data and anomaly alerts.

The best way to get a health summary for rollback decisions is to run post-deploy canary monitoring. It triggers alerts when anomalies are detected and provides an at-a-glance health summary to guide your rapid triage process.
