  • The architectural advantages only pay off at a scale most deployments never reach

Bruno

  • Native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month
  • OpenAPI syncs are capped at 5 a month on the free tier
  • SSO, SCIM and user management require Ultimate at $11 per user per month
  • Private workspaces are a paid feature
  • Advertised prices are annual rates

Answered from the vendors’ own pages

Apache Pulsar: Is Apache Pulsar free?

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.

Bruno: What is the difference between Bruno Pro and Ultimate plans?

Pro ($6/month) includes native Git integration and unlimited workspaces. Ultimate ($11/month) adds SSO/SCIM support, audit logs, 24-hour support (vs. 48-hour), and an account manager. Ultimate supports unlimited OpenAPI syncs while Pro is limited to 5 per month.

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.

Bruno: How much does Bruno Pro save compared to other API tools?

The vendor claims Ultimate saves teams more than 70% versus Postman, though this comparison is promotional rather than a specific cost metric.
