Built to make the rota bearable

From cleanly enriched alerts to a mobile app people actually open, every piece is built to be quick, obvious and quiet.

Suggested summary

Problem: custom shifts intended to be 5+2 days are rendering as 5+5 days because of a timezone rounding bug in the rota preview.

Make onboarding a non-event

99.94%

We’re up when you’re down

3.1 million pages delivered last year at 99.94% reliability — so a critical moment never lands in the void.

Read the reliability paper

Infrastructure resilience at Klaxon We engineered the delivery platform around a single obsession: the page always arrives, even when everything else is on fire.

Easy to move, whatever your size

Teams from 3 to 2,400 engineers have switched their rota to Klaxon — we stay with you at every step.

Import in an afternoon

Connect your current pager, pull in schedules and escalation paths, and dual-run safely until you’re confident enough to cut over.

API and Terraform

We speak your SRE’s language. Configure the whole on-call estate programmatically, or check the entire thing into version control.

A human on your side

Enterprise teams get a named onboarding engineer who shapes the migration around how your org is genuinely structured.

What makes on-call so painful for most teams?

The three failure modes we see over and over:

Alert fatigue — teams drowning in false positives, with the one page that mattered buried in the noise,
Lopsided load — a handful of engineers absorbing roughly 3× the pages of everyone else, and
Tool sprawl — separate systems for rotas, alerting, and the incident itself.

Klaxon closes all three: triage models drop up to 74% of low-signal pages, fairness tracking shows exactly who carried the week, and rotas, alerts, incidents and status pages all live on one platform.
