The short version

  • Only Restate has a free tier, so it costs nothing to try first.
  • Each has a real cost: Aha! sold as eight separate products rather than one subscription, so Roadmaps, Discovery, Ideas, Whiteboards, Builder, Develop, Teamwork and Knowledge are each priced per user; 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: Aha! covers Strategic roadmaps, 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.

Aha!

  • Sold as eight separate products rather than one subscription, so Roadmaps, Discovery, Ideas, Whiteboards, Builder, Develop, Teamwork and Knowledge are each priced per user
  • Roadmaps at $59 per user per month is expensive next to general project tools, and Discovery and Ideas add $39 each
  • The Develop integration with Roadmaps requires the Enterprise or Enterprise+ tier
  • Annual billing is by invoice only; monthly is card

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.
