 Durable Objects are only available on the [Workers Paid plan](/workers/platform/pricing/#workers). Durable Objects limits are the same as [Workers Limits](/workers/platform/limits/), as well as the following limits that are specific to Durable Objects:
 
-| Feature                                  | Limit for class with key-value storage backend                   | Limit for class with SQite storage backend <sup>1</sup> |

-<sup>3</sup> Each incoming HTTP request or WebSocket *message* resets the remaining available CPU time to 30 seconds. This allows the Durable Object to consume up to 30 seconds of compute after each incoming network request, with each new network request resetting the timer. If you consume more than 30 seconds of compute between incoming network requests, there is a heightened chance that the individual Durable Object is evicted and reset.
