Introduction
Entrig is the notification layer for Supabase. It sends notifications to your users based on events in your Supabase database. You define when to trigger and who to notify. Entrig handles the rest, with no backend code.
Channels
| Channel | What you need | SDK required |
|---|---|---|
| A sending domain you verify once | No | |
| Push | An FCM or APNs credential, plus the Entrig SDK in your app | Yes |
Email is the fastest way to start. You verify a domain you own, add a sender, and Entrig delivers email straight from your database events. No app changes and no SDK. This is the right channel for order receipts, status updates, digests, and any message that reaches a user by address rather than by device.
Push reaches users on their device. Because push is addressed to a device rather than an email, it needs the Entrig SDK in your app to register device tokens, plus an FCM (Android) or APNs (iOS) credential.
Who it is for
Entrig is for developers building on Supabase who need notifications driven by database events, such as:
- An order status changing
- A message arriving for a user
- A task being assigned
- An admin broadcasting an announcement
What you need to get started
- A Supabase project
- For email: a domain you can add a DNS record to
- For push: an FCM or APNs credential (or both) and the Entrig SDK integrated in your app
Start with Email for the quickest path, or set up Push if you need to reach users on their device.
