The short version

  • Each has a real cost: Harness essentials and Enterprise pricing requires sales contact; no published rates; 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.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Harness

  • Deploying apps to AWS, Azure, and Google Cloud with rollbacksnot Restate
  • Integrating security scanners throughout build pipelines before productionnot Restate
  • Automating cloud cost reduction and tracking unit-level expensesnot Restate
  • Enabling developers to provision infrastructure without operations bottlenecksnot Restate
  • Assessing deployment frequency and lead time productivity metricsnot Restate

Restate

  • Payment or order flows where a crash between two external API calls must not double-charge or lose the ordernot Harness
  • AI agent loops that call tools over minutes or hours and must survive a deployment mid-runnot Harness
  • Replacing hand-rolled retry, idempotency key and outbox code across a set of microservicesnot Harness
  • A small team that wants durable workflows without operating a Temporal cluster and its databasenot Harness

Where each one falls short

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

Harness

  • Essentials and Enterprise pricing requires sales contact; no published rates
  • DevOps Essentials has no on-premises deployment option
  • Internal Developer Portal requires minimum 20 developer licenses
  • Pipeline execution history retention 6 months (Essentials) vs 25 months as add-on (Enterprise)

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.

Answered from the vendors’ own pages

Harness: Is there a free Harness plan?

Yes, Harness offers a free plan for individual developers and small teams with open source options including Harness Open Source and Litmus Chaos.

Source
Restate: Is Restate open source?

The SDKs are MIT. The runtime is under a Business Source Licence, which permits self-hosting but not offering it as a competing service.

Harness: What are Harness's paid pricing tiers?

Harness offers Essentials for growing teams and Enterprise for large-scale organizations. Both require contacting sales for custom pricing. Pricing is based on modules and features selected.

Source
Restate: How does it compare with Temporal?

Same problem, different shape: one Rust binary with embedded storage instead of a server plus database plus workers, and lower per-step latency.

Harness: Can Harness be deployed on-premises?

Enterprise plans include self-managed platform deployment option. DevOps Essentials bundle does not offer on-premises deployment.

Source
Restate: Is there a free tier?

Yes, fifty thousand durable actions a month on Restate Cloud with no card required.
