Bubble's Workload Unit

What is bubble? is a no-code development platform that allows users to create web and mobile applications without having to write code. When building an application on, the platform uses a Workload Unit (WLU) system to measure the amount of computational resources required to run your application.

What is Workload Unit?

A Workload Unit (WLU) is a unit of measurement used to determine the amount of server resources required to run an application. One WLU is equivalent to a single core of a 2.4 GHz Intel Xeon processor, along with 2 GB of RAM and 10 GB of storage.

When you create an application on, the platform assigns a certain number of WLUs based on the size and complexity of your application. As your application grows and requires more resources to handle user traffic and data processing, you may need to purchase additional WLUs to ensure that your application runs smoothly. offers different pricing plans based on the number of WLUs required for your application, with plans ranging from a free plan that includes 1 WLU to enterprise-level plans that can support hundreds of WLUs. The number of WLUs required for your application will depend on factors such as the number of users, the complexity of your application, and the amount of data being processed.

Workload Tiers

If you do need more, you have the option to subscribe to an additional workload tier if your app is on the Starter, Growth, or Team plan.

Here are a handful of examples to give you a sense of what it looks like to scale on Bubble. (App names have been anonymized to protect privacy.)
