# Rate limits and quotas

> Learn about the service limits applied to Applications, Workflows, and Scheduled Jobs to optimize the performance and stability of the Superblocks cloud

<Alert type="info">
  The following applies only to customers on the Superblocks Cloud architecture. It does <strong>not</strong> apply to customers using the Superblocks Hybrid or Cloud-Prem architectures (<a href="/enterprise/deployment-overview">details</a>).
</Alert>

For users on Superblocks Cloud, tier based service limits are in place to optimize product performance and stability. If you need higher service limits for your use case, please reach out to our [support team](/enterprise/support/help) to request a limit increase.

## Time quotas

| Quota | Description | Free | Trial | Pro | Enterprise |
| - | - | - | - | - | - |
| Application API duration | Duration of an API in an Application | 30 seconds | 5 minutes | 5 minutes | 5 minutes |
| Workflow duration | Duration of a Workflow | 30 seconds | 10 minutes | 10 minutes | 10 minutes |
| Scheduled Job duration | Duration of a Scheduled Job | 1 minute | 30 minutes | 30 minutes | 30 minutes |
| Language step duration | Duration of any language step (Python / JavaScript) in an Application, Workflow, or Scheduled Job) | 1 minute | 1 minute | 2 minutes | 2 minutes |

## Size quotas

| Quota | Description | Free | Trial | Pro | Enterprise |
| - | - | - | - | - | - |
| Step size\* | Step output returned | 5 MB | 10 MB | 20 MB | 20 MB |
| Stream send size | Size of data sent to the client per message for streaming APIs | 500 kB | 500 kB | 1 MB | 2 MB |
| Parallel pool size | Number of paths that can be used in the Parallel block | 10 | 10 | 50 | 50 |

\* The **step size** refers to an API step's *output* (return value + console logs). You can still process in excess of these limits *within* a language step as long as the data is not returned. Note, API steps return serialized JSON which is included in this limit.

### Returning data from the Application backend to the frontend

<Alert type="info">
  The following applies only to organizations whose payload quota is set at > 10 MB.
</Alert>

When returning data from backend API steps to the frontend, it is recommended to keep it below **10MB** for performance reasons. Returning more data could cause degraded performance for end-users. This may require the use of server-side pagination to limit the payload of the data.

## Rate limits

API steps are rate limited. The **throughput** of steps cannot exceed the following limits.

| Rate Limit | Description | Free | Trial | Pro | Enterprise |
| - | - | - | - | - | - |
| Steps per second - User | Steps executed per second for an individual user | 500 | 500 | 5000 | 5000 |
| Steps per second - Organization | Steps executed per second across an entire organization | 5000 | 5000 | 50000 | 50000 |
| Steps per second - API | Steps executed per second for a single API | 500 | 500 | 5000 | 5000 |
