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.
Knowing who’s on call is half of it. We do the other half.
Call or text the on-call person in one click — and let your AI assistant do it too. OnCallRadar is wired to actually reach people, not just point at them.
Call or text, straight from the roster.
No copy-pasting numbers, no digging through a wiki. Tap once to place a real phone call or send an SMS to whoever’s on call. If they don’t pick up, OnCallRadar cascades down your escalation chain — three attempts each — until someone acknowledges.
Your on-call, inside any AI assistant.
A built-in MCP server lets Claude and other AI agents tell you who’s on call and page the right person until they acknowledge — safely, scoped to your org’s own token. Prefer to script it? The same power is a REST API call away.
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.
