Modes With Their Own Policies
Home, Away, Night, and your own custom modes - each binding its own escalation policy and false alarm delay. Night wakes the household; Away calls the neighbours.
Your Alarm Goes Off. The People You Trust Know in Seconds.
A break-in. A water leak at the cabin. The freezer door at 2am, the furnace at minus 30. OpenAlarm takes the trigger from the system you already run - Home Assistant, UniFi Protect, anything that can call a URL - and texts, calls, and emails your people, in order, until someone acknowledges.
Free is free: no card, no contract. The waitlist is first in at launch.

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:

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
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.
Messenger, Not Monitor
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.

Know the Moment It's Live
OpenAlarm is almost ready. Leave your email and you're in first when it opens - early access, nothing more to it. Fair pricing, and a free tier that's actually useful.
