The short version

  • Each has a real cost: Maze maze publishes no prices on its pricing page; every plan routes to contact sales, so pricing is by quote only with no published rate or minimum; 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.
  • They diverge on capability: Maze covers Prototype testing, Restate covers Durable execution.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Maze

  • Maze publishes no prices on its pricing page; every plan routes to contact sales, so pricing is by quote only with no published rate or minimum
  • The AI study builder, AI moderated interviews and moderated interview studies are Enterprise only
  • Mobile testing and testing through the Maze mobile app are Enterprise only
  • Interview scheduling, card sorting and information architecture testing are Enterprise only
  • Role-based access, SSO and compliance controls are Enterprise only
  • Panel recruitment is available on all plans but with stated limits, and prototype testing carries limits below Enterprise
  • Qualitative analysis of clip recordings, interview transcription and automated theme analysis are Enterprise only

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.
