  • A much smaller ecosystem of connectors, tooling and hiring pool than Kafka
  • The architectural advantages only pay off at a scale most deployments never reach

Braze

  • Implementation costs of $20k-$100k+ significantly increase total cost of ownership

Yes, open source under the Apache Software Foundation.

Apache Pulsar: Pulsar or Kafka?

Pulsar separates storage from compute and covers queuing and streaming in one system. Kafka has a far larger ecosystem and hiring pool. Most teams should have a specific reason before choosing Pulsar.

Braze: Does Braze offer implementation support?

Implementation through a Braze Solutions Partner typically costs $20,000 to $100,000 or more, as Braze is an enterprise platform requiring custom configuration.

Source
Apache Pulsar: Why does separated storage matter?

Brokers hold no data, so adding or replacing one requires no rebalancing, and storage can grow without adding serving capacity.

Braze: What messaging channels does Braze support?

Braze supports push notifications, in-app messaging, email, SMS, and web messaging across mobile apps and web platforms.
