Restate
Durable execution engine in Rust with a free tier and low-latency workflows
As of 31 August 2026, Restate has a free plan and paid plans start at $300/month. A durable execution runtime competing with Temporal, written in Rust and shipped as a single binary rather than a cluster of services. Softwr lists it under Developer Tools. Restate is available on Linux, macOS, Web.
Overview
What Restate does
Restate runs code that has to survive process crashes, network failures and restarts: workflows, sagas, event handlers and increasingly AI agent loops. It journals every step and every external call so that after a failure the code resumes at the exact point it reached rather than starting over. SDKs exist for TypeScript, Java, Kotlin, Go, Python and Rust, and the same programme runs against a locally started server, a self-hosted cluster or Restate Cloud. The distinguishing engineering choice is deployment shape. Temporal needs a server, a database, workers and a UI to be run and operated. Restate is one Rust binary with embedded storage, which makes a local development loop and a small production deployment enormously cheaper in operator time. It also targets much lower per-step latency than the JVM-based alternatives, which is what makes it usable for request-path work rather than only for long-running background workflows. The commercial detail worth checking before you commit: the Restate runtime is under a Business Source Licence, described by the company as an Amazon defence rather than a general restriction, while the SDKs are MIT. That is fine for running it yourself and a problem if your business model involves offering it as a managed service. Restate Cloud has a genuine free tier of fifty thousand durable actions a month, then jumps to 300 US dollars a month for twenty million actions, with additional actions at 25 dollars per million. The gap between free and 300 dollars is the one that surprises people.
What people use it for
- Payment or order flows where a crash between two external API calls must not double-charge or lose the order
- AI agent loops that call tools over minutes or hours and must survive a deployment mid-run
- Replacing hand-rolled retry, idempotency key and outbox code across a set of microservices
- A small team that wants durable workflows without operating a Temporal cluster and its database

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about 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, with sources
Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
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.
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.
Is there a free tier?
Yes, fifty thousand durable actions a month on Restate Cloud with no card required.
Which languages are supported?
TypeScript, Java, Kotlin, Go, Python and Rust.
