### Follow the steps below to deploy ToolJet on Heroku:

1. Click the button below to start one click deployment.  
   <div style={{textAlign: 'center'}}>

   [![Deploy](https://www.herokucdn.com/deploy/button.svg)](https://heroku.com/deploy?template=https://github.com/tooljet/tooljet/tree/main)

   </div>

2. On Heroku tab, you'll be asked to provide an `App name` and `Choose a region`. Enter the name for your deployment and select the region according to your choice.

</div>

3. Now let's enter the `Config vars` to configure additional [environment variables](/docs/setup/env-vars) that are required for the installation.
   - **LOCKBOX_MASTER_KEY**: ToolJet server uses lockbox to encrypt datasource credentials. You should set the environment variable LOCKBOX_MASTER_KEY with a 32 byte hexadecimal string. If you have OpenSSL installed, you can run the command `openssl rand -hex 32` to generate the key.
   - **NODE_ENV**: By default NODE_ENV is set to production. 
   - **NODE_OPTIONS**: Node options are configured to increase node memory to support app build.
   - **SECRET_KEY_BASE**: ToolJet server uses a secure 64 byte hexadecimal string to encrypt session cookies. You should set the environment variable SECRET_KEY_BASE. If you have OpenSSL installed, you can run the command `openssl rand -hex 64` to generate the key.
   - **TOOLJET_HOST**: Public URL of ToolJet installation. This is usually `https://<app-name-in-first-step\>.herokuapp.com`.
   - **TOOLJET_SERVER_URL**: URL of ToolJet server installation. (This is same as the TOOLJET_HOST for Heroku deployments)


4. Click on `Deploy app` button at the bottom to initiate the build.

5. After the successful build, you'll see two buttons at the bottom: `Manage App` and `View`. Click on the `View` to open the app or click on `Manage App` to configure any settings.

</div>

6. The default username of the admin is `dev@tooljet.io` and the password is `password`.

:::tip
The one click deployment will create a **free dyno** and a **free postgresql database**.
:::

:::tip
ToolJet server and client can be deployed as standalone applications. If you do not want to deploy the client on Heroku, modify `package.json` accordingly. We have a [guide](/docs/setup/client) on deploying ToolJet client using services such as Firebase.

## Upgrading to the Latest Version

The latest version includes architectural changes and, hence, comes with new migrations.

If this is a new installation of the application, you may start directly with the latest version. This guide is not required for new installations.

#### Prerequisites for Upgrading to the Latest Version:

- It is **crucial to perform a comprehensive backup of your database** before starting the upgrade process to prevent data loss.

- Ensure that your current version is v2.23.0-ee2.10.2 before upgrading. 

- Users on versions earlier than v2.23.0-ee2.10.2 must first upgrade to this version before proceeding to the latest version.

For specific issues or questions, refer to our **[Slack](https://tooljet.slack.com/join/shared_invite/zt-25438diev-mJ6LIZpJevG0LXCEcL0NhQ#)**.
