The short version
- 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.; Warp limited cloud agents access on free tier

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.
Warp
- Limited cloud agents access on free tier
- Limited collaboration features on free tier
- Limited cloud conversation storage on free tier
- IME input not properly handled on macOS (discarded during command or Agent output)
- Terminal zoom functionality does not properly resize grid in TUI applications, causing misaligned rendering
- Multi-language (i18n) support missing as of documentation
- Requires macOS 10.14 or later (excludes older Mac hardware)
- Requires Windows 10 build 1903 or later (excludes pre-build 1903 systems)
- Linux requires glibc 2.31 or higher and GPU support (OpenGL ES 3.0+ or Vulkan) for rendering

Questions people ask
- Is Restate or Warp better?
- Neither clearly leads. Restate starts at Free and Warp at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Restate or Warp?
- Restate starts at Free and Warp at Free.
- Does Restate or Warp run on more platforms?
- Restate runs on Linux, macOS, Web. Warp runs on macOS, Windows, Linux.
- 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 Warp is typically brought in for.
- What can Restate do that Warp cannot?
- Restate covers Durable execution, Virtual objects, Single binary runtime, Multi-language SDKs.
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.
Warp: What is the pricing model?
Usage-based, priced per agent run. Qualifying orgs get $10k of factory usage during closed early access.
SourceRestate: 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.
Warp: Where does our data live?
Data lives wherever you choose - Warp's cloud, or fully self-hosted inside your own VPC, under your existing retention and compliance rules.
SourceRestate: Is there a free tier?
Yes, fifty thousand durable actions a month on Restate Cloud with no card required.
Warp: What is included in the free trial?
Get up to $10,000 in free factory usage during early access.
SourceRestate: Which languages are supported?
TypeScript, Java, Kotlin, Go, Python and Rust.
