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.
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.
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.

### Deploying Tooljet Database
If you intend to use this feature, you'd have to set up and deploy PostgREST server which helps querying ToolJet Database.
This feature is only enabled if `ENABLE_TOOLJET_DB` is set to `true` in the Tooljet application.
#### Follow the steps below to deploy ToolJet Database on Heroku:
:::note
Please install Heroku CLI on your local machine. Please refer Heroku CLI installation steps [**here**](https://devcenter.heroku.com/articles/heroku-cli).
:::
1.**Create a new Heroku app using the PostgREST buildpack**
1.1 Create a folder with your app name. Please give a unique name to the app.
You can get the `${HEROKU_PG_DB_NAME` of the Tooljet application from the Resources tab under Heroku Postgres attachments as shown below. (eg: `${HEROKU_PG_DB_NAME = postgresql-transparent-24158` ).
You can also refer environment variable [**here**](/docs/setup/env-vars#tooljet-database).
:::tip
If you have openssl installed, you can run the following command `openssl rand -hex 32` to generate the value for `PGRST_JWT_SECRET`.
If this parameter is not specified then PostgREST refuses authentication requests.
:::
```bash
heroku config:set PGRST_JWT_SECRET=
heroku config:set POSTGREST_VER=10.0.0
```
You can also refer environment variable [**here**](/docs/setup/env-vars#tooljet-database).
5.**Build and deploy your app**
```bash
git add Procfile
git commit -m "PostgREST on Heroku"
git push --set-upstream heroku main
```
Your Heroku app should be live at `${YOUR_APP_NAME}.herokuapp.com`.
6.**Additional environment variables for Tooljet application**
Please enter the below env variables in the Tooljet application, under the setting tab. You can also refer environment variable [**here**](/docs/setup/env-vars#tooljet-database).
