Frequently asked questions

Can I keep using existing Pusher SDKs?

Yes. Socketo implements the official Pusher Protocol v7. Channels (public, private, presence), client events, and HMAC authentication work out of the box with pusher-js, Laravel Echo, and other official Pusher SDKs.

What does "Zero Fan-Out Tax" mean?

Pusher bills for every subscriber that receives an event (e.g. 1 broadcast to 1,000 users = 1,000 billed messages). Socketo bills 1 broadcast regardless of subscriber count. 1M broadcasts are included monthly, then $1 per million.

How do I migrate my project?

Change 3 environment variables: PUSHER_HOST, PUSHER_APP_KEY, and PUSHER_APP_SECRET. See the migration guide for details.

Can I self-host Socketo for free?

Yes. The GPLv3 open-source community edition is available on GitHub and can be run on Docker, Kubernetes, or locally via npx @socketo/cli.
