Example setting Prisma Client level debugging output:

export DEBUG="prisma:client"

See Debugging for more information.

NO_COLOR

NO_COLOR if truthy will activate the colorless setting for error formatting and strip colors from error messages.

Prisma Studio

BROWSER

BROWSER is for Prisma Studio to force which browser it should be open in, if not set it will open in the default browser.

bash

Alternatively you can set this when starting Studio from the CLI as well:
