Durable Objects
The Cloudflare Workers Driver is an implementation that uses Cloudflare’s Durable Objects for actor state persistence and coordination. It leverages Cloudflare’s global network for low-latency, distributed actor systems that can scale automatically.
You rarely need to manually configure drivers. The platform package you’re using will configure the appropriate drivers for you. See the documentation for your platform for details.

| Node.js | Standalone |
| Bun | Coordinate |
| Cloudflare Workers | Partition |
| Rivet |
Usage
There’s no need to explicitly configure drivers when using ActorCore with Cloudflare Workers. The platform package automatically sets up the appropriate drivers.
See the Cloudflare Workers Platform documentation for complete setup instructions.
Limitations
The Cloudflare Workers driver has several limitations to be aware of:
- Storage Limits: Storage is limited to Cloudflare’s Durable Objects size limits
- Cost: Requires Cloudflare Workers Paid plan for Durable Objects usage
- Platform Lock-in: Your implementation will be specific to the Cloudflare Workers platform
For a platform-agnostic approach with similar global distribution capabilities, consider using Rivet instead.
