The short version

  • Each has a real cost: Ably standard and Pro plans layer usage-based charges for messages, connection minutes, and data transfer on top of the base subscription, adding cost complexity.; Apollo GraphQL pricing beyond the Developer tier requires contacting sales, making cost comparison harder for mid-size teams.
  • They diverge on capability: Ably covers Pub/sub messaging, Apollo GraphQL covers Apollo Connectors.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Ably

  • Standard and Pro plans layer usage-based charges for messages, connection minutes, and data transfer on top of the base subscription, adding cost complexity.
  • The jump from Standard ($29/month) to Pro ($399/month) is steep for teams needing more than 10k connections but not full Pro capacity.
  • 24/7 mission-critical support and 99.999% uptime SLAs are reserved for the custom-priced Enterprise tier.

Apollo GraphQL

  • Pricing beyond the Developer tier requires contacting sales, making cost comparison harder for mid-size teams.
  • Adopting GraphOS effectively requires buy-in to the GraphQL paradigm, which is a larger architectural shift than adding a REST gateway.
  • The free plan's 1-day data retention and 60 req/min self-hosted router limit make it unsuitable for production use.
  • Volume-based per-request pricing can become expensive at very high request volumes compared to flat-rate API gateways.
