Custom Environment Variables

You can customise Companion Hub’s behaviour by overriding environment variables.

The main .env file is auto-generated and should not be edited directly — it gets regenerated on every start. To set custom values, create a file named .env.local in the cihome directory. Values in .env.local will override the corresponding values in .env.

Not all environment variables can be safely overridden. Only override values you understand — incorrect settings may prevent Companion Hub from starting.

See Environment Variables for a full list of available variables and Folder Structure for where these files live.
