The short version

  • Each has a real cost: esbuild deliberately does not type-check TypeScript, only strips types, so tsc still runs separately; 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: esbuild covers Very fast builds, Restate covers Durable execution.
  • 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.

esbuild

  • Libraries and tools needing a fast, embeddable bundlernot Restate
  • Replacing slower bundlers where the plugin ecosystem is not needednot Restate

Restate

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

Where each one falls short

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

esbuild

  • Deliberately does not type-check TypeScript, only strips types, so tsc still runs separately
  • Plugin API is far narrower than webpack or Rollup, and complex builds hit its limits
  • Code splitting support has historically lagged the more established bundlers
  • Frequently used indirectly through Vite, so direct use is a narrower need than the download numbers suggest

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

esbuild: Is esbuild free?

Yes, open source under the MIT licence.

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.

esbuild: Does esbuild type-check TypeScript?

No. It strips types for speed and does not check them. Run tsc separately if you need type checking.

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.

esbuild: Do I need esbuild if I use Vite?

You already have it. Vite uses esbuild internally for dependency pre-bundling and transforms.

Restate: Is there a free tier?

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

Restate: Which languages are supported?

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