Alarm alerting for the security system you already own

Your Alarm Goes Off. The People You Trust Know in Seconds.

OpenAlarm is an alarm alerting platform. You keep your own alarm system - Home Assistant, UniFi Protect, anything that can call a URL - and when it goes off, OpenAlarm texts, calls, and emails the people you trust, in order, until someone answers. We provide the alerting. You provide the alarm. Pro is free for 14 days for all new users.

No card, no contract.

Not just burglary

Alerting for Everything a Monitoring Company Won't Dispatch For

Break-ins first - the moment your alarm trips, your people know. That job is table stakes. But your home knows about more than intruders, and if a sensor can see it, your people can know about it - one product for every "someone should know" in your life:

The missing middle

You Shouldn't Have to Choose Between Fragile and Locked In

A DIY Notification

  • One push notification, easily missed
  • Nobody acknowledges, nothing escalates
  • No false-alarm handling
  • Telephony you build and maintain forever

OpenAlarm

  • Texts, calls, and email - in your order
  • Escalates until someone acknowledges
  • False alarm delay before anyone is woken
  • Your hardware, your people, no contract

A Monitoring Contract

  • A call center, not your people
  • Camera bundles you didn't ask for
  • Contracts and lock-in
  • Only responds to what they cover

How it works

From Trigger to Your People, in One Hop

Point Anything at a URL

Home Assistant, Alarmo, a UniFi Protect webhook, a curl. If it can make an HTTP request, it can trigger.

We Fan It Out

Texts, calls, and email to the contacts you chose, in the order you set. The false alarm delay holds first - a quick disarm and nobody hears a thing.

Someone Acknowledges

One tap on the alert. Escalation stops, you see who has it, and they see your instructions.

Nobody Answers? It Escalates

The next level is alerted, then the next - and a repeating policy starts over rather than going quiet.

Built like a product, priced like a tool

More Than a Webhook Relay

Modes With Their Own Policies

Home, Away, Night, and Vacation - each binding its own escalation policy and false alarm delay. Night wakes the household; Away calls the neighbours.

Test Mode That Tells the Truth

Trip the sensor for real. The whole chain runs and records - who, in what order, on which channel - and nobody is contacted until you flip to live.

Every Property, One Account

The house, the cabin, the rental - each location with its own alarms, address, test switch, and dashboard.

Panic Buttons

No modes, no arming, no waiting. Press, and your people's phones light up.

Send-Only API Keys

A key can fire an alarm and read nothing. Scope it to one alarm and a leaked webhook config still can't touch the rest.

Incidents, Not Noise

Repeat triggers fold into one open incident with a full record: every alert, every acknowledgment, start to close.

Open where it counts

Works With Anything. Leaves With You.

The Home Assistant integration and SDKs are open source; the hosted service is the paid part. Any hardware that can call a URL is supported hardware, and nothing about your setup is locked to us - your panel, your sensors, and your automations stay yours.

Trust

No Cameras. No Call Center. No Contract.

We Alert. We Never Watch.

We deliver alerts and request a response. We never watch anything, and there is no footage because there are no cameras.

Your Contacts Stay in Control

Every person consents before they can be alerted, every message carries a way out, and an opt-out is theirs alone to reverse.

Your Data Is Yours

We store what alerting needs and nothing else. Delete your account and everything goes with it, immediately - no retention games.

Pricing

Free Emails Your People. Pro Texts and Calls Them.

Both plans do everything - every alarm, every contact, escalation until someone answers. Free alerts your people by email, forever. Pro is $6.99 a month and adds SMS and voice calls, because an email waits until morning and a ringing phone does not. The full comparison lives on one page, with nothing hidden.

Start Free. Upgrade When It Matters.

No card for Free, no contract for Pro, and your first alarm is one URL away.
