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.

TIBCO Mashery

  • Lack of support for open API standards requires workarounds
  • Policy management is difficult and sometimes requires support intervention for configuration changes
  • Monetization and customization features are inadequate for some enterprise use cases
  • Delays under heavy load conditions; stability issues reported affecting performance
  • Logging and monitoring limitations; logs are hard to follow when calls cannot be filtered by keys
