Eventeer vs Svix
Svix is built around sending webhooks to your own customers. Eventeer is a hosted hub for the events you receive and relay: webhooks, device WebSockets and WebSocket feeds, stored and replayable. Here is where each one fits.

When to choose Eventeer
- You receive events: provider webhooks, device telemetry, a third-party WebSocket feed. You want one place to take them in, store them and relay them.
- You have devices that hold a WebSocket open and need acknowledgements, online status and a way to send messages back.
- You want to fan events out to browsers or services over WebSocket streams, with replay after a reconnect.
- You want metrics on a JSON field and alerts when a listener or device goes quiet.
When to choose Svix
- Your product sends webhooks to your customers, and each customer needs to register endpoints, filter event types and read delivery logs. Svix's embeddable portal exists for that.
- You want a webhook sending service with per-endpoint throttling, payload transformations and multi-region delivery.
- You need to self-host. Svix publishes an open source server.
The two can sit side by side: Svix for the webhooks you send to customers, Eventeer for the events you receive.
Migrating
If you only used Svix to verify or receive webhooks, the move is short. If you send webhooks to customers through Svix, keep that part where it is.
- Create an organization and a webhook listener for each provider that posts to you.
- Pick an auth mode per listener: anonymous, token or HMAC-signed.
- Point the provider at the new listener URL. Keep the old endpoint running until traffic is confirmed in the event list.
- Add a destination that forwards stored events to your service, and check its delivery log.
- Verify signatures on your side against the
X-Eventeer-Signatureheader, then retire the old endpoint.
