SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Quickly detect production issues after a deployment by watching a live app for errors, performance regressions, and visual anomalies, ensuring you catch problems before users notice.

Core Features & Use Cases

  • Continuous live-monitoring with automated checks, screenshots, and console/log analysis to surface anomalies.
  • Baseline comparison against pre-deploy data to detect regressions and visual differences.
  • Quick post-deploy verification workflow on canary or production URLs to trigger alerts and triage.

Quick Start

Run /canary <url> to start a 10-minute monitoring session on the specified URL.

FAQPage Schema
How do I monitor a production app for errors and visual regressions after a deploy?

You can monitor a production app after a deploy by running a continuous live-monitoring session that uses automated checks, periodic screenshots, and console tracing to detect errors, performance regressions, and visual anomalies on live URLs.

What is canary deployment monitoring and how does baseline comparison work?

Canary deployment monitoring tracks live app health by comparing post-deploy metrics and screenshots against pre-deploy baselines to detect regressions and visual differences, ensuring you catch problems before users notice.

How do I start a post-deploy verification session on a specific URL?

You can start a 10-minute post-deploy verification session by running the /canary <url> command on the specified production or canary URL to trigger automated anomaly detection and alerting.

Do I need a browse daemon to collect events for production alerting?

Yes, you need a browse daemon to collect events, perform baseline comparisons, take periodic screenshots, and apply alerting thresholds for rapid anomaly detection during your post-release workflow.

Can I integrate automated visual regression checks with my deployment workflow?

Yes, you can integrate automated visual regression checks and baseline comparisons with your deployment workflow to perform rapid post-release verification and trigger alerts across multiple URLs and environments.
