Canary Watch — Post-Deploy Monitoring

What problem does it solve?

After a production or staging release, regressions can slip through despite tests—users then hit broken pages, rising errors, or degraded performance before you notice.

Core Features & Use Cases

• Post-deploy URL monitoring: Continuously checks an HTTP endpoint for failures and page health.
• Regression detection vs baseline: Flags new console errors, network failures, and performance metric shifts (LCP/CLS/INP) compared to a prior baseline.
• Launch-window alerting: Applies critical/warning/info thresholds and can notify via desktop and optional webhook, while logging results for auditability.
• Use case: Verify that a risky fix actually worked by running a diff-style comparison between staging and production, then watching for any new console errors or 5xx responses.

Quick Start

Run the canary check against your deployed URL to detect HTTP, console, network, and performance regressions.
