Hey, I'm Greg, the PM working on Durable Objects at Cloudflare. As part of the private beta, we're looking to get feedback on the best way to price Durable Object so they're accessible for all applications - small or large.

While we're in beta, storage access will be free. As we're thinking about it now, once we're out of beta this wouldn't be included in the base $5/mo plan.

Since there's both a compute component (a Durable Object runs code, like a Worker) and a storage component (for storage operations) to the product, we want the long-term pricing model to mesh those two in a transparent, competitive way.

While we're not finalized on price yet, you can expect that costs for storage will be cheaper than existing services like AWS DynamoDB or Google Cloud Firestore when we move out of beta.

For those in the beta, it's currently free. We are still working out what pricing will look like post-beta. We realized we need to see how people actually use it and get some feedback before we could settle on the right pricing structure... that's what betas are for.

As others said, we’re figuring out pricing during beta but hope to keep it in-line with pricing for Workers KV. And it may be possible for us to get pricing even lower than that.
