Knock is a multi-channel notification-workflow platform (email, SMS, push, in-app) built around its own delivery infrastructure. Pushbrain is push-specific and routes delivery through your own Firebase project. Here is how the two compare for teams that specifically need push.
Knock is built as a multi-channel workflow engine — email, SMS, push, and in-app feed, orchestrated through one workflow builder. Pushbrain is deliberately push-only: if your product only needs push notifications, Pushbrain is a smaller, more focused tool rather than one channel inside a broader orchestration platform.
Knock delivers push through its own infrastructure and prices around usage/workflow volume. Pushbrain uses your own Firebase project for delivery, so the delivery hop itself is free regardless of volume — you pay Pushbrain a flat monthly rate for the management layer (dashboard, scheduling, AI copy, A/B testing), not per notification sent.
No. Knock's workflow builder is designed for orchestrating multi-step, multi-channel journeys. Pushbrain instead focuses on push-specific automation: scheduled jobs, drip campaigns, weather-gated sends, and AI Autopilot for recurring copy — narrower in channel scope, but purpose-built for push rather than a general orchestration layer.
If your app already has a Firebase project for push, Pushbrain integrates directly against it — no separate delivery account or channel provider configuration needed. Knock, as a multi-channel platform, requires configuring Knock's own push credentials/channel setup regardless of whether you already have Firebase in place.
