How it works

1. Get an API key

Sign up and grab your API key.

2. Pair your iOS devices

Download the ActivitySmith app and pair your device to your account. Each paired device can start receiving Live Activities and Push Notifications in seconds.

3. Send updates from any runtime

Call the API from your backend, worker, cron job, automation, AI agent, or GitHub Action. Use Live Activities for long-running processes and Push Notifications for immediate events.

Integrate in minutes

Pick your stack and start sending Push Notifications and Live Activities in a few lines of code.

import ActivitySmith from "activitysmith";
const activitysmith = new ActivitySmith({
  apiKey: process.env.ACTIVITYSMITH_API_KEY!,
});
await activitysmith.notifications.send({
  title: "New subscription 💸",

For Teams

Works for teams, not just solo developers

Invite teammates, let each person pair their own iPhone or iPad, and keep releases, incidents, and long-running jobs visible across the team. Use channels when you need to scope delivery to specific teammates, groups, or devices instead of notifying everyone.

FAQ

Do I need to build my own mobile app to receive these alerts?

No, that's the best part. ActivitySmith provides a dedicated, ready-to-use iOS app. You don't have to write a single line of Swift or manage App Store submissions. Just download our app, pair your device, and start pushing alerts from your backend in minutes.

Do I need an Apple Developer account or push certificates?

No. Because you are sending alerts to the ActivitySmith app rather than your own custom app, we handle all the APNs (Apple Push Notification service) handshake. You don't need to manage certificates, identifiers, or provisioning profiles.

Can I use ActivitySmith to send notifications to my own app's users?

No. ActivitySmith is not an SDK for your own mobile apps. It's a service that lets you send notifications from any backend to the ActivitySmith iOS app.

What is the benefit of using the ActivitySmith app instead of Slack/Discord?

Standard chat apps don't support iOS Live Activities or rich push notifications. ActivitySmith allows you to have a persistent, updating widget on your Lock Screen or Dynamic Island for things like 'Server Migration Progress' or 'Build Status' that you simply can't do with a standard push notification.
