Pusher refers to Pusher Channels. Its daily allowance and Pubb’s free monthly quota use different reset windows. Prices exclude applicable tax.
Count the audience,
not just the publish.
One event can create many billable messages or capacity operations. Model your subscriber count, connection peaks and event rate before choosing a plan.

This is a capacity example, not a price estimate or delivery guarantee. Disconnected or slow clients can miss events.
Read the unit behind the price
Pusher counts API publications and subscriber deliveries against its daily allowance. Pubb paid plans have no monthly message quota; operation rate and bandwidth still limit how much traffic can flow at once. Size either plan for your audience and peak activity.

Pusher Channels
Channel messaging with fixed tiers
For teams that prefer Pusher’s client and server libraries, private and presence channels, and daily message allowances.

Before you choose.
Is Pubb an alternative to Pusher Channels?
Pubb supports channel events, private subscriptions and presence for notifications, dashboards and shared activity. Compare the SDKs, traffic limits and cache behavior your app needs before choosing.
How do Pubb and Pusher count messages?
Pusher counts publications plus subscriber deliveries toward a daily allowance. Pubb paid plans have no monthly message quota, but publications and delivery attempts consume operation and bandwidth capacity. Peak event rate matters as well as audience size.
Do both services have presence channels?
Yes. Both support presence channels for membership information and events. Their SDK interfaces and authorization flows differ, so adapt and test membership handling during a migration.
Does Pubb have Pusher-style cache channels?
Pubb does not provide a last-event cache or a message history API. Fetch durable state from your application after reconnecting. Pusher cache channels can return the most recent event to a new subscriber, with a TTL of up to 30 minutes; they do not provide a full event history.
Can I use a Pusher SDK with Pubb?
Do not assume drop-in compatibility. Use a Pubb SDK or the documented HTTP and WebSocket APIs, and adapt publishing, subscriptions and channel authorization. Verify reconnect behavior before moving production traffic.
