Bubble has a usage-based pricing model, so users will only pay for the resources their app needs. Our mission is to make software development more accessible — Instead of requiring users to monitor various resources in a traditional tech stack built with code, we introduced a single metric: workload.
Workload aggregates the server resources needed to host, run, and scale apps built on Bubble. The amount of workload an app consumes is measured in workload units (WU). Learn more in the Workload section in the Bubble Manual.

The amount of workload an app needs depends on a variety of factors. If you’re new to Bubble, the best way to assess your workload needs is to get started on a Free plan. From within your free app, you will be able to see how the activities unique to your app contribute to workload usage. The Free plan comes with more than enough workload to build and explore. To learn more, see our workload explainer.

Yes, you can disable overages at any time so that your app does not use more than the amount that comes with your plan (plus any additional workload you may have purchased via a workload tier).
