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

GraphQL Apollo

  • Standard and Enterprise plans require sales contact for custom pricing
  • Free plan limited to 3 developers and 1-day retention
  • Self-hosted router on free tier heavily rate-limited to 60 requests/minute

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.

GraphQL Apollo: Is there a free version of Apollo GraphQL?

Yes, Apollo GraphQL offers a forever-free plan with no credit card required for up to 3 developers, including 1-day data retention, community support, and self-hosted GraphOS Router rate-limited to 60 requests per minute.

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.

GraphQL Apollo: What does Apollo's Enterprise plan include that Standard does not?

The Enterprise plan offers unlimited developers versus 30 on Standard, 18-month data retention versus 90 days, and 24x7x365 business support with SLA instead of 8x5 support. It also includes premium and professional services add-ons and custom MSA agreements. Both require custom pricing.
