SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring helps teams detect errors, performance regressions, and visual anomalies in production before users are impacted, reducing MTTR and risk.

Core Features & Use Cases

Watches the live app for console errors, performance regressions, and page failures using a dedicated canary workflow.
Takes periodic screenshots, compares against pre-deploy baselines, and alerts on anomalies to drive rapid remediation.
Use cases include validating new releases, catching regression bugs, and verifying that critical paths remain healthy after deployment.

Quick Start

Invoke after deploying a new version to automatically monitor the live app against baselines and surface issues.

FAQPage Schema

How do I monitor my app for errors after a production deploy?▼

Post-deploy canary monitoring detects production errors by capturing periodic screenshots and comparing live app behavior against pre-deploy baselines to surface anomalies. It runs automatically after deployment to catch regressions before users are impacted.

What is post-deploy canary monitoring and when do I need it?▼

Post-deploy canary monitoring is a technique that validates new releases by watching live apps for console errors and performance regressions. You need it after deploying a new version to verify critical paths remain healthy and reduce mean time to remediation.

How do I catch visual regressions in production after releasing a new version?▼

To catch visual regressions in production, the workflow takes periodic screenshots of the live app and compares them against pre-deploy baselines. It issues alerts when visual anomalies or page failures exceed acceptable thresholds.

Do I need pre-deploy baselines to monitor my live app for regressions?▼

Yes, pre-deploy baselines are required to monitor your live app for regressions. The canary monitoring process depends on comparing current production runtime metrics and screenshots against these established baselines to detect anomalies.

What is the best way to alert my team about performance regressions in production?▼

The best way to alert your team about performance regressions is to configure a post-deploy canary workflow that issues alerts when anomalies exceed thresholds. This requires an alerting or reporting channel to drive rapid remediation.
