canary-watch

Post-deploy monitoring detects regressions by running a looping watch on a deployed URL to identify HTTP status changes, new console errors, performance regressions, and content drift. It uses configurable intervals, durations, and threshold-based alerts to verify availability after deploys.

The best way to detect HTTP status changes after a PR merge is applying post-deploy monitoring to the target URL. This approach watches for availability shifts, new console errors, and content drift, enabling threshold-based alerts and optional webhook notifications to inform rollback decisions.

Yes, you can compare production and staging URLs using Diff mode. This mode contrasts the live URLs to detect content drift, HTTP status changes, and performance regressions, providing alerts that help verify environment integrity across deployments.

Yes, canary-watch supports CI integration and webhook notifications. It can be integrated into deployment pipelines to provide threshold-based alerts and optional notifications via desktop alerts and webhooks, ensuring deployment workflows capture post-deploy regressions.

Yes, you can apply post-deploy monitoring for dependency upgrades. By running a sustained watch or quick check on the deployed URL, the monitoring detects new console errors, performance regressions, and content drift caused by the upgraded dependencies.
