SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Post-deploy canary monitoring solves the gap between deployment and production reality by watching the live app for console errors, performance regressions, and page failures. It takes baseline references, captures screenshots, and raises alerts when anomalies are detected so teams can act before end users suffer.

Core Features & Use Cases

  • Continuous post-deploy health checks with automated breadcrumbs (console, perf, and UI signals)
  • Baseline capture and comparison with screenshots to detect regressions
  • Real-time alerting and health reporting for production deployments

Quick Start

Invoke /canary <url> to start a 10-minute post-deploy health check on the provided URL.

FAQPage Schema
How do I monitor production after deployment to detect performance regressions?

Post-deploy monitoring captures baseline references, console health signals, and automated screenshots to detect production performance regressions and page failures. It raises real-time alerts when anomalies occur so teams can act before end users suffer.

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

Post-deploy canary health monitoring watches live web apps for console errors, performance regressions, and page failures immediately after deployment. You need it to bridge the gap between deployment and production reality, ensuring baseline stability.

How do I run a quick post-deploy health check on a web app URL?

To run a quick post-deploy health check, invoke the monitoring command with your target URL to start a configured duration validation. The monitor applies automated breadcrumbs, capturing console, performance, and UI signals for baseline comparisons.

Do I need a browse-like agent to automate post-deploy validation screenshots?

Yes, post-deploy validation requires integration with a browse-like agent to automate screenshots, perform baseline comparisons, and trigger anomaly alerting. This browser integration enables continuous health checks and real-time reporting across configured pages.

What's the best way to set up real-time alerting for web app console errors?

The best way to set up real-time alerting for console errors is using a post-deploy canary monitor that applies baseline capture and comparison with automated screenshots. It triggers alerts when anomalies are detected during continuous health checks.

Can I configure the duration and pages for post-deploy health checks?

Yes, post-deploy health checks support configurable duration and target pages for validation. You can run a 10-minute baseline comparison on a provided URL, ensuring console health and performance baselines match expected production states.
