Show HN: Entrig – Push notifications for Supabase without backend code

Push notifications are essential for mobile apps, yet they’re still a major friction point. Many developers choose Supabase or Firebase specifically to avoid backend code, but eventually end up writing server-side logic or Edge Functions just to send notifications.

I built Entrig to eliminate that hassle. It lets you send push notifications without any server setup and without writing code, purely based on your database events.

How it works: Entrig leverages Supabase/Postgres triggers. When you create a notification in the Entrig Dashboard, the required trigger function is automatically created in your database. On the client side, the SDK handles token management when you initialize it in your app.

The goal is to make push notifications truly plug-and-play, so you can focus on building your product, not wiring backend logic just for push notifications.

I’d love to hear your feedback on the product and approach.
