What problem does it solve?
Undetected regressions after production deploys, risky code merges, or dependency upgrades can break user experience and impact business metrics before teams are aware of the issue.
Core Features & Use Cases
- Comprehensive Regression Checks: Monitors HTTP status, console errors, network failures, performance metrics (LCP/CLS/INP), critical page content, and API endpoint health against defined baselines.
- Flexible Watch Modes: Supports quick single-pass checks, sustained interval monitoring for custom durations, and side-by-side staging versus production diff comparisons.
- Configurable Alerting: Sends desktop notifications and optional Slack/Discord webhook alerts when critical thresholds are breached, with separate warning and info level logging for minor variances.
- Use Cases: Ideal for post-deploy verification, validating bug fixes, continuous monitoring during high-traffic launch windows, and post-dependency upgrade sanity checks.
Quick Start
Use the canary-watch skill to monitor your production application URL for 2 hours with 5 minute interval checks immediately after your latest deploy to catch any unexpected regressions.
