SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring helps teams catch production issues early by continuously watching a live URL for console errors, performance regressions, and visual failures, and by surfacing actionable alerts.

Core Features & Use Cases

  • Baseline capture before deployment
  • Automated page checks and anomaly alerts
  • Configurable pages, duration, and alert rules for production monitoring

Quick Start

Start a canary run on the deployed URL to baseline, monitor pages, and alert on anomalies.

FAQPage Schema
How do I monitor a live URL for console errors and performance regressions after a production deployment?▼

Post-deploy monitoring checks a live URL every 60 seconds to detect console errors, performance regressions, and visual changes, comparing the deployed state against a captured baseline to alert you to anomalies for fast reliability verification.

What is a baseline capture and when do I need it for production monitoring?▼

A baseline capture records the healthy state of your pages before a deployment. You need it during production monitoring to establish a reference point for detecting visual changes, console errors, and performance regressions after new code goes live.

How do I set up automated page checks and anomaly alerts for post-deploy verification?▼

Configure target pages, monitoring duration, and alert rules to start a canary run. The system automatically loads live pages every 60 seconds, checks for anomalies against the baseline, and generates a structured health report for post-deploy verification.

Do I need a browse daemon to run post-deploy canary monitoring?▼

Yes, you need a browse daemon to load live pages for post-deploy canary monitoring. The daemon enables the system to render URLs, capture the baseline, and perform the automated per-page checks required to detect visual and performance regressions.

Can I configure alert rules and monitoring duration for specific production pages?▼

Yes, production monitoring supports configurable pages, duration, and alert rules. You can define which specific URLs to watch, set the monitoring window, and establish custom alerting thresholds to receive a structured canary report for post-deploy verification.

What does a structured canary report include for post-deploy reliability checks?▼

A structured canary report includes the results of automated per-page checks for console errors, performance regressions, and visual changes. It surfaces actionable alerts based on your configured rules and the captured baseline to verify post-deploy reliability.
