| # Executions | |
| An execution is a single run of a workflow. | |
| ## Execution modes | |
| There are two execution modes: | |
| * Manual: run workflows manually when testing. Select **Test Workflow** to start a manual execution. You can do manual executions of active workflows, but n8n recommends keeping your workflow set to **Inactive** while developing and testing. | |
| * Production: a production workflow is one that runs automatically. To enable this, set the workflow to **Active**. | |
| ## Execution lists | |
| n8n provides two execution lists: | |
| * [Workflow-level executions](/workflows/executions/single-workflow-executions.md): this execution list shows the executions for a single workflow. | |
| * [All executions](/workflows/executions/all-executions.md): this list shows all executions for all your workflows. | |
| n8n supports [adding custom data to executions](/workflows/executions/custom-executions-data.md). | |
