    You can set a key prefix

    limiter = Limiter(
    app,
    key_func=get_remote_address,
    default_limits=["200 per day", "50 per hour"],
    storage_uri='redis://localhost:6379',
    key_prefix='DTM',
)

    This changes the keyname from

    LIMITER/127.0.0.1/slow/1/1/day

    to

    LIMITER/DTM/127.0.0.1/slow/1/1/day

    To add to the response by namizaru: you can only control some parts of the key with this library.

    Given the example from namizaru:

    LIMITER/127.0.0.1/slow/1/1/day

    The string "LIMITER" comes from the limits library (https://github.com/alisaifee/limits), which Flask-limiter wraps. I don’t see a good way to override this.

    "127.0.0.1" is the result of the key_func parameter passed to Limiter (get_remote_address) and should return a unique string that identifies the rate-limited resource, as far as I understand. So, you can provide your own callable there, but that only changes one portion of the key.

    Meanwhile, the delimiter ("/") also comes from the limits library and does not seem overridable.
