Where each one falls short

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

Exa

Usage-based pricing can be unpredictable without volume discounts upfront
Enterprise customers need to contact sales for custom volume discount plans

Restate

The runtime is under a Business Source Licence rather than an open source licence, so building a competing managed offering on it is prohibited and some procurement functions will reject it on licence grounds alone
Restate Cloud jumps from a free fifty thousand actions straight to 300 US dollars a month for twenty million, so a workload sitting at a few hundred thousand actions pays enterprise-shaped money for hobby-shaped volume
It is a young project against Temporal’s established base, so hiring engineers who already know it is unrealistic and the answer to most questions is in the docs rather than on Stack Overflow
The programming model requires structuring code around durable handlers and virtual objects, which is a genuine rewrite for existing services rather than a library you add
The single-binary simplicity that makes small deployments cheap also means fewer operational knobs at very large scale than a system designed as separable components
