Wake the right engineer. Let everyone else sleep.
The agent responds first. Schedules and escalations are the last line of defense — and they don't stop at voicemail.
Rules you can read aloud
The policy is the sentence. The ladder is yours. No YAML archaeology at 3am.
Escalations in plain English
If nobody acknowledges in five minutes, call the on-call. Then the next person up. Then the team admins — with repeat loops and auto-close when every step has run.
You decide how you get woken
Call after one minute, SMS after three, email after five. Quiet hours hold low-priority noise until morning — each responder sets their own ladder.
The life of a page
From alert to acknowledged — what happens when it's real.
The alert gets routed
Severity, tags, source, message — routing rules send each alert to a schedule or straight into an escalation policy.
The phone rings — and rings on
Warrn calls, listens for a human, and takes acknowledge or resolve from the keypad. An answering machine is not an answer — the escalation moves to the next person.
A human takes it from here
Acknowledged, escalation stopped, timeline updated — and the investigation the agent started is already waiting in the alert.
What you open when you answer
Acknowledge from the call, open the alert — the agent's investigation, suggested actions, and the alert's full context are already there. On your laptop or your phone.
The agent does the repetitive work. You make the calls.
On-call as a collaboration — with guardrails that keep anything touching production behind a human.
A fixed first response, per alert type
Encode the steps once. Every alert of that type gets the same investigation before a human is paged — and anything that writes waits for approval.
Wake up to a hypothesis, not a wall of graphs
One or more suspected causes, each with the evidence behind it. You check the reasoning, not the dashboards.
Work with it like a colleague
On the phone, on the web, in Slack, or in the warroom on a Meet. Same agent, same context, wherever you already are.
Rules you talk into existence
Describe the routing you want and the alert engine writes the if-this-then-that for you. No more juggling conditions by hand.
The boring parts, done properly
Overrides & covers
Swap a shift in one click — cover a single rotation or the whole schedule.
In your calendar
Every schedule is an iCal feed. Shifts sit next to your meetings.
Shift reminders
A nudge before every shift starts — push and email, on your schedule.
Layers, restrictions & honest history
Stack a business-hours rotation over a 24/7 one. Handoffs stay correct across DST — and editing a rotation never rewrites who was actually on call.
“Who's on call?”
Answered in the sidebar with your shift countdown — and in Slack.
