Canary Watch

Watches a deployed URL for regressions in HTTP status, console errors, network failures, performance, content, APIs, static assets and SSE streams.

If a Slack or Discord webhook is configured, monitoring results are sent to that third-party service.

Core rule

Alert immediately when any critical threshold is crossed, such as a non-200 status or a 5xx from an API.

Execution Phases

  1. Phase 01Pick a watch mode

    Default to a single quick check, or run a sustained watch with an interval and duration, or compare staging against production.

  2. Phase 02Run the checks

    Check HTTP status, console errors, network requests, LCP/CLS/INP, key page elements, API health, static assets and SSE heartbeats.

  3. Phase 03Classify by threshold

    Compare results to the baseline and sort them into critical, warning and info.

  4. Phase 04Notify and report

    On critical breaches, send a desktop notification and log it, optionally post to Slack or Discord, then output a canary report table.
