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.
Ory
- Production and Growth plans are billed annually ($770/year and $9,350/year), which is a larger upfront commitment than monthly-only competitors.
- SAML SSO and multi-region deployments are reserved for the custom-priced Enterprise tier.
- Usage-based pricing across aDAU, M2M tokens, and permission checks makes cost estimation more complex than flat per-MAU billing.
