🌍 Environment Variable Configuration

Overview​

Open WebUI provides a range of environment variables that allow you to customize and configure various aspects of the application. This page serves as a comprehensive reference for all available environment variables, including their types, default values, and descriptions.

info

Last updated: v0.3.20

App/Backend​

The following environment variables are used by backend/config.py to provide Open WebUI startup configuration. Please note that some variables may have different default values depending on whether you're running Open WebUI directly or via Docker. For more information on logging environment variables, see our logging documentation.

General​

ENV​

  • Type: str (enum: dev, prod)
  • Options:
    • dev - Enables the FastAPI API docs on /docs

  • Description: This setting enables or disables authentication.
danger

If set to False, authentication will be disabled for your Open WebUI instance. However, it's important to note that turning off authentication is only possible for fresh installations without any existing users. If there are already users registered, you cannot disable authentication directly. Ensure that no users are present in the database, if you intend to turn off WEBUI_AUTH.

AIOHTTP_CLIENT_TIMEOUT​

  • Type: int
  • Default: 300
  • Description: Specifies the timeout duration in seconds for the aiohttp client.
