Smart Alerts
When metrics cross the line

Get notified when monitored metrics cross the lines you set: email digests and in-product signals today; additional channels per roadmap. Cooldowns and sensible defaults reduce fatigue from noisy deploys while still surfacing sustained problems. Alerts link scheduled test results to the engineers and account leads who fix production performance.

Why it matters

Less inbox noise, faster response, clear ownership.

Budget-driven

Thresholds from performance budgets define when an alert exists.

Multi-channel (where enabled)

Email today. Slack and webhooks are planned for tiers that include them.

Cooldowns by design

Repeat scheduled failures do not generate an endless notification thread.

From test result to notification

A test completes, we evaluate it against your budgets, and an alert record is created when something breaches. Organisation admins receive email today; wire Slack when your plan supports it.

Example thresholds: LCP, INP, CLS, performance score, aligned with Performance budgets.

Cooldown and resolution

Stage System behaviour
Open breach Notify; start cooldown window
While failing Suppress duplicate alerts until state changes
Passes budget Resolve; ready to alert again on next breach

What is coming

We are extending routing and analytics so large teams can steer noise away from the wrong inboxes. Until those ship, email plus in-product signals remain the backbone. On the roadmap: team routing, escalation rules, and alert analytics (frequency, time to resolve).
