The CrateDB Admin UI

CrateDB ships with a web administration user interface (or Admin UI).

The CrateDB Admin UI runs on every CrateDB node. You can use it to inspect and interact with the whole CrateDB cluster in a number of ways.

You can access the Admin UI via HTTP on port 4200:


Replace HOSTNAME with the hostname of the CrateDB node. If CrateDB is running locally, this will be localhost.

Navigate to this URL in a web browser.


If you access port 4200 via a client library or command-line tool like curl or wget, the request will be handled by the CrateDB Rest API, and the response will be in JSON.
