# Compute Manager

> Control panel for managing your qBraid Lab server instances

The Compute Manager extension offers a seamless interface to manage your computing environment.
You can effortlessly start, stop, and control your server, and switch between various compute
instances including CPU, GPU, and custom configurations—all directly from the qBraid Lab interface.

## Basic Usage

Open the Compute Manager extension by clicking on "Compute" in the qBraid Lab top-bar:

  <img src="https://storage.googleapis.com/qbraid-static-assets/qbraid-docs/lab/compute-manager-basic.png" width="150%" />
</div>

Filter instances by `ALL`, `CPU`, or `GPU`. All compute instances are available by default.

The CPU instance usage is bound by your compute hours limit.

</div>

GPU instances are billed per minute using qBraid [credits](/v2/home/pricing#credits).

## Stop Instance

* Click "Stop" next to the currently running instance to stop your server directly from the jupyter lab.

<Warning>
  Before stopping your instance, ensure that you've saved your work. Any unsaved
  changes will be lost.
