# The Open Source Notification Orchestration Layer.

Send notifications, automate follow-ups and track delivery with one API.

- [Start sending](https://buzzkit.dev/dashboard)
- [BuzzKit on GitHub](https://github.com/buzzkit-dev/buzzkit)

## Notifications made easy.

Bring your provider credentials and let BuzzKit do the heavy lifting, from choosing who to notify to tracking actual delivery.

- **Send with one call.** Send to a person or an audience. BuzzKit finds their devices and handles delivery.
- **Multi-tenant by design.** One workspace, a tenant per customer, each with its own subscribers, topics and credentials, sealed off from the rest.
- **Your keys, your data.** Your own provider credentials, encrypted, with no markup on messages and no shared provider account.

## Send a push with one call

```
POST /v1/messages
{
  "to": "user_42",
  "topic": "gym-reminders",
  "title": "Leg day",
  "body": "Let's go. 6:00 with Maya.",
  "deepLink": "app://workouts/legs"
}
```

BuzzKit queues the notification and returns a message ID you can use to check delivery status.

## Everything you need, built in.

### Workflows

Build event-based workflows with waits, conditions and follow-ups, with zero custom code.

- Quiet-moment delivery
- Dry runs before publish
- Version history

### Segments

Reach new users, paying customers or people who haven’t opened your app in a week.

- Attribute and event conditions
- Inline expressions on a send
- Live preview counts

### Scheduling

Send at 9 a.m. in each user’s time zone, with quiet hours and daily limits built in.

- Subscriber-timezone sends
- Quiet hours and daily caps
- Cancel until the last minute

### Topics & preferences

Let users choose what they receive, with preferences automatically applied to every send.

- Choices per topic and channel
- Defaults with overrides
- Preferences API

### Sources

Connect integrations or custom webhooks to trigger notifications from the tools you already use.

### Live Activities

Start, update and end Live Activities for orders, scores and more, using the same API as your push notifications.

## See what happened to every push.

See whether a push was sent, delivered or opened, and why it failed, with automatic retries on failure.

- Automatic retries for temporary failures
- Delivery and open receipts per device
- Progress for each message
- Request retries without a second message

## Add the SDK. Skip the token management.

Register your users and devices with the Swift SDK, which keeps device tokens up to date and tracks events even when offline.

- Action buttons and deep links
- Event tracking while offline
- Live Activities and push-to-start
- Targeting by push permission

## Let your agent set it up.

Point your agent at the BuzzKit skill and it adds notifications to your app and your backend, with agent-friendly pages it can read along the way.
