[Cassandra Workbench](https://marketplace.visualstudio.com/items?itemName=kdcro101.vscode-cassandra "Cassandra Workbench") is a free Visual Studio Code extension for browsing and querying Cassandra databases. It also features autocomplete and syntax highlighting.

This tutorial shows how to install Cassandra Workbench and configure a connection.

## Before you begin

To use Cassandra Workbench with YugabyteDB, you need to have the following

- YugabyteDB up and running. Refer to [YugabyteDB Prerequisites](/stable/integrations/tools/#yugabytedb-prerequisites "YugabyteDB Prerequisites").
- Visual Studio Code [installed](https://code.visualstudio.com "installed").

## Install the Cassandra Workbench extension

To install the extension, do the following:

1. Start Visual Studio Code and from the **Go** menu, choose **Go to File**.
   
   ![Visual Studio Code Quick Open](/images/develop/tools/vscodeworkbench/vscode_control_p.png "Visual Studio Code Quick Open")
2. Enter the following command.
   
   ```sh
   ext install kdcro101.vscode-cassandra
   ```

Cassandra Workbench is now available in the **Activity** bar.

2. Open the Command Palette (View>Command Palette) and enter the following command to generate the .cassandraWorkbench.jsonc configuration file:
   
   ```sh

   ```
3. In the Cassandra Workbench, click **Edit configuration** to open the configuration file.
4. Replace `contactPoints` with the host address, and username and password with your credentials (the default user and password is `cassandra`).
   
   ```json
   // name must be unique!
   [
       // AllowAllAuthenticator
       {
           "name": "Cluster AllowAllAuthenticator",
           "contactPoints": ["127.0.0.1"]
       },
       //PasswordAuthenticator
       {
           "name": "Cluster PasswordAuthenticator",
           "contactPoints": ["127.0.0.1"],
           "authProvider": {
               "class": "PasswordAuthenticator",
               "username": "cassandra",
               "password": "cassandra"
           }
       }
   ]
   ```

You can now explore your YCQL schema and data.
