The short version

  • Womp is free; Restate starts at $300/mo.
  • Only Restate lists durable execution; only Womp lists implicit surface modelling.
  • Where Womp falls short: nothing is dimensionally accurate, so a form designed here has to be remodelled in CAD before it can be manufactured.
  • Prices and features on this page were last checked on 31 August 2026.

What people use each for

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

Restate

  • Replacing hand-rolled retry, idempotency key and outbox code across a set of microservicesnot Womp
  • A small team that wants durable workflows without operating a Temporal cluster and its databasenot Womp

Womp

  • Teaching 3D concepts without installing software on managed machinesnot Restate

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

Womp

  • Everything runs through the browser graphics stack, so an older laptop with integrated graphics hits frame rate and render limits fast and there is no local rendering fallback
  • Implicit modelling gives no control over the exported mesh, so the output topology is unsuitable for rigging, animation or subdivision work downstream
  • Nothing is dimensionally accurate, so a form designed here has to be remodelled in CAD before it can be manufactured
  • Scenes live in the vendor account, so if the service changes or closes, the only copies you hold are whatever you exported in advance
  • The material and lighting set is deliberately simplified, which caps art direction and makes the output visually recognisable as having come from Womp

Questions people ask

Is Restate or Womp better?
Neither clearly leads. Restate starts at Free and Womp at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Restate or Womp?
Restate starts at Free and Womp at Free.
Does Restate or Womp run on more platforms?
Restate runs on Linux, macOS, Web. Womp runs on Web.
Can I use Restate for free?
Both have a free tier, so you can try either at no cost before committing.
What is Restate best used for?
Restate is most often used 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. Of those, payment or order flows where a crash between two external api calls must not double-charge or lose the order and ai agent loops that call tools over minutes or hours and must survive a deployment mid-run are not what Womp is typically brought in for.
What can Restate do that Womp cannot?
Restate covers Durable execution, Virtual objects, Single binary runtime, Multi-language SDKs. Womp covers Implicit surface modelling, Browser rendering, Material library, Scene sharing.

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.

Womp: Do I need to know 3D to use it?

No. That is the point of the modelling approach; there is no topology, edge flow or subdivision to understand.

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.

Womp: Can I use the meshes in Blender or a game engine?

You can export them, but the topology comes from tessellating an implicit surface, so it is not suitable for rigging, animation or subdivision without a retopology pass.

Restate: Is there a free tier?

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

Womp: Is it accurate enough for manufacturing?

No. It is a visual tool. Anything to be made needs remodelling in CAD.

Restate: Which languages are supported?

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