## Overview

Developer mode provides additional tools and features to help you integrate and debug Documenso.

## Field Information

When enabled, developer mode displays the following information for each field:

- **Field ID** - The unique identifier of the field
- **Recipient ID** - The ID of the recipient assigned to the field
- **Pos X / Pos Y** - The position of the field on the page
- **Width / Height** - The dimensions of the field

To enable developer mode, add the `devmode=true` query parameter to the editor URL.

```bash
# Legacy editor

https://app.documenso.com/t/<team-url>/documents/<envelope-id>/legacy_editor?devmode=true
```
