Know who to call the second it matters.
No guesswork at 3am. When production's down, you stay calm.
Everything you need to answer one question, fast.
OnCallRadar keeps the answer simple on the surface and the flexibility underneath — so anyone can start in minutes and grow into it later.
Who's on call, now
A single live view per schedule — the on-call person, their contact channels, and exactly who's next. Reach them in one tap.
Schedules & approvals
Build rotations on a real calendar, propose changes, and route them to approvers. Edits publish only once they're signed off.
Escalation that has your back
If nobody's on a shift, OnCallRadar falls back through your escalation chain automatically — so a call never hits a dead end.
From zero to on-call in three steps.
Create your roster
Sign in with Google, Microsoft or email. Name your organization — that's the whole setup.
Invite your team
Add people by email and how to reach them — phone, WhatsApp, Signal, Telegram. Order them by priority.
Build the schedule
Drop shifts on the calendar or spin up a rotation. Send it for approval, and you're live.
Up and running in under 15 minutes.
No onboarding calls, no implementation project. OnCallRadar is designed so any team can stand up a working on-call roster before the coffee's cold.
Stop guessing who to call.
Give your team one calm, reliable answer for every high-pressure moment — starting today.
