The short version

  • Only Restate has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Wasabi 90-day minimum storage duration with no option to delete before full period without penalty
  • They diverge on capability: Restate covers Durable execution, Wasabi covers Hot Cloud Storage.
  • 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.

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.

Wasabi

  • 90-day minimum storage duration with no option to delete before full period without penalty
  • Significantly smaller global footprint than AWS with only 16 regions, resulting in higher latency for users in underserved regions
  • Performance can degrade with high-volume transactions requiring throughput management strategies
  • Hot storage only, no cold/archival storage tier for long-term data at lower cost
  • Support responsiveness gaps with teams experiencing multi-day waits for critical issue resolution

Answered from the vendors’ own pages

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.

Wasabi: What is Wasabi's pricing structure?

Wasabi offers pay-as-you-go pricing at $7.99 per TB per month as of July 2026, with no egress or API request fees. Reserved capacity plans are available for multi-year terms with volume discounts.

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.

Wasabi: Does Wasabi charge for data downloads or API calls?

No. Wasabi includes zero egress fees and zero API request fees, which is a major cost advantage over AWS S3. Customers can plan their budget to the penny without worrying about surprise data transfer charges.

Source
Restate: Is there a free tier?

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

Wasabi: Is there a minimum storage duration requirement?

Yes. Wasabi enforces a 90-day minimum storage term. Users who delete data before 90 days are still charged for the full 90-day period.

Source
Restate: Which languages are supported?

TypeScript, Java, Kotlin, Go, Python and Rust.

Wasabi: Is Wasabi S3-compatible?

Yes. Wasabi Hot Cloud Storage is fully S3-compatible, meaning organizations can integrate it into existing workflows without rewriting application code used with AWS S3.
