# App Usage
> Understand how Zite charges for app usage through credits and workflow runs.
Zite usage is measured in two main ways: **credits** and **workflow runs**. Credits cover usage-based actions such as AI work and email sends. Workflow runs cover successful workflow executions from published apps.
Credits power usage-based features in your Zite workspace, including building and editing apps with AI, using the Database Agent, generating AI fields, using AI in apps with Zite's API key, and sending emails from published apps.
Some actions do not use credits, including manual design edits, users visiting published apps, editor workflow runs, editor emails, and login emails such as magic links.
See what uses credits, what does not, how credits reset, and where to check credit usage.
A workflow run is one successful execution of a workflow from a published app. It counts as one workflow run no matter how many steps, nodes, integrations, loops, or bulk operations the workflow includes.
Workflow runs are tracked separately from credits. Runs from the editor do not count toward your monthly workflow run limit and do not consume credits.
Learn how workflow runs are counted, how they relate to credits, and how to review workflow history.
