Pagerstack
Alerting · On-call · Incident response

Pagerstack collapses a wall of alerts into one page to one owner, opens the war room, pins the runbook, and writes the timeline while you fix it. Median acknowledge is 38 seconds — and the postmortem is half-drafted before the incident is resolved.

  • Routes on service ownership, not a shared inbox
  • Escalates with judgment, not just a 5-minute timer
  • Plugs into the alerts you already send

The platform

From first alert to signed-offpostmortem, on one thread.

Most on-call tools just forward noise to a phone. Pagerstack decides who owns it, how loud to be, and what to do next — then keeps the record, so the 2 a.m. you and the 9 a.m. you are reading the same story.

Routing that knows who owns the code

Every alert is matched to the service that fired it and sent to that service's rotation — not a catch-all channel a dozen people half-watch. Ownership lives next to the service in a versioned catalog, so when teams reorg, paging follows automatically and nobody inherits a page for code they've never touched.

Escalation with judgment

If the primary doesn't ack, Pagerstack climbs the chain — secondary, then lead, then manager — and quiets the channels it already woke. It respects working hours, follow-the-sun handoffs, and the engineer who's already heads-down on a different SEV1.

Alert grouping that ends the storm

One bad deploy shouldn't fire 400 pages. Correlated alerts — same service, same release, same blast radius — collapse into a single incident, so you chase the cause once instead of acking the symptoms forty times.

War rooms that open themselves

Declare a SEV2 and Pagerstack spins up the Slack channel, the video bridge, and an incident-commander prompt in the same second — no hunting for the right link while the graphs are still red.

Runbooks pinned at the moment of need

The runbook for this service and this failure mode surfaces inside the incident, stamped with when it was last used and a one-tap 'step done' so a handoff never loses its place.

On-call, humanely

The pager should respectthe person carrying it.

Burnout is a reliability risk. Pagerstack treats the on-call engineer as the scarcest resource on the team — and defends their attention like one.

Schedules people actually trade

Drag-and-drop rotations, one-tap overrides, and self-serve swaps that don't wait on a manager's approval. Coverage gaps surface before the week starts, not at 3 a.m. when the gap is already a page.

Quiet hours that hold

Low-severity alerts wait for morning unless they escalate. Sleep is protected by default, and every override is written to the log so the policy can't quietly erode.

Fatigue scored, not guessed

Pagerstack tracks off-hours pages, ack latency, and back-to-back incidents per person, then flags the lead before a rotation grinds someone down — while there's still time to rebalance.

Hand off with the full context

Pull in a teammate and they land already briefed — timeline, suspected cause, what's been tried. No 'can someone catch me up?' tax in the middle of the fire.

The incident, end to end

Five stages.One thread thatnever drops.

Every incident moves through the same arc — Pagerstack carries the context across all of it, so nothing gets re-explained and nothing falls between two people at a shift change.

00:00

Detect

Forty-one alerts from one bad deploy fold into a single incident. You see the cause, not a scrolling wall of duplicates fighting for attention.

00:04

Route

The page lands on the payments rotation that owns the failing service — matched from the catalog, not broadcast to a channel and left for someone to claim.

00:41

Mobilize

Ack, and the war room is already live: Slack channel, video bridge, incident commander assigned, and the runbook pinned to the exact failure mode.

08:34

Resolve

The suspect deploy is surfaced, the db owner is pulled in already briefed, the rollback ships, and error-rate drops to 0.2% — all on one timeline.

after

Learn

A draft postmortem is waiting — responders, impact, and suspected cause filled in. You add the contributing factors and assign action items, then close the loop.

Fits your stack

Connects to whateveralready pages you.

Point your existing monitors at Pagerstack and you're live by the afternoon. No rip-and-replace, no proprietary agent on every box, no instrumentation rewrite.

Alerts from anywhere

Native ingest for Prometheus, Datadog, Grafana, CloudWatch, and Sentry, plus a signed webhook for everything that isn't on the list yet.

ChatOps where you live

Acknowledge, escalate, and resolve from Slack or Teams. The bot keeps the channel and the incident timeline in lockstep, so the record matches the conversation.

Reach you anywhere

Push, SMS, phone call, and email — every notify carries a delivery receipt, so a missed push always falls through to a ringing phone instead of silence.

Deploy-aware context

Wire in your CI and Pagerstack pins the releases that landed right before the spike straight into the incident — the first suspect is in front of you on arrival.

On-call as code

Define rotations, escalation policies, and routing rules in Terraform. A coverage change gets reviewed in a pull request like the rest of your infrastructure.

One signed API

Trigger, update, and close incidents programmatically with idempotent calls and a replayable event stream — so your own automation can drive the same flow.

From the people holding the pager

Teams stopped dreadingthe rotation.

We went from 400 pages a week to under 150 in a month. Grouping alone handed the team back their nights — and now our SEV1s are acked before I've found my laptop in the dark.

The escalation logic just gets it. It pulled in our database owner already briefed, skipped the three people who couldn't have helped, and we'd shipped the rollback before the old tool would have finished its first round of paging.

Postmortems used to be a day of digging through Slack to reconstruct who did what, when. Now the timeline assembles itself and the retro is spent on fixes instead of forensics.

Priced per responder. Page all you want.

You pay for the people who carry the pager — never per alert. Flooding the night with noise shouldn't cost you more; fixing it should cost you less.

Straight answers for the on-call engineer.

Do I have to replace my monitoring?

No. Pagerstack sits on top of what you already run. Point Prometheus, Datadog, Grafana, CloudWatch, Sentry, or a plain signed webhook at us and alerts start routing — no proprietary agent, no rip-and-replace, no instrumentation rewrite.

How is alert grouping different from just deduping?

Dedup squashes identical alerts. Pagerstack correlates related ones — same service, same deploy, same blast radius — into a single incident, so a cascading outage becomes one page to one owner instead of four hundred. You fix the cause once instead of acking the symptoms.

What stops it from paging people in the middle of the night for nothing?

Severity-aware routing and quiet hours. Low-severity alerts wait until morning unless they escalate, working hours are honored per person, and a fatigue score warns leads before a rotation burns someone out. Every override is logged so the policy stays honest.

How fast can we be live?

An afternoon. Connect one alert source, import a schedule (or build one with drag-and-drop), set an escalation policy, and you're paging. Most teams run their first real incident on Pagerstack the same day they sign up.

Can we manage on-call as code?

Yes. Rotations, escalation policies, and routing rules all live in our Terraform provider and a signed API, so on-call changes get reviewed in a pull request like the rest of your infrastructure — no clicking through a UI to reorg coverage.

What happens after the incident is resolved?

Pagerstack hands you a draft postmortem with the full timeline, every responder, the suspected cause, and customer impact already filled in. You add the contributing factors and assign action items with owners and due dates — the reconstruction is done for you.
