General environment variables

Reference documentation for general environment variables.

General environment variables available for use with Self-hosted Retool deployments.

Only configure environment variables when needed. You can configure many environment variables from your organization's Settings rather than directly editing your deployment's configuration file.

You must restart your instance after setting any variables for them to take effect.

All properties for this object with supported data types or values. You can write JavaScript almost anywhere in Retool to manipulate or read property values.
