Connecting from your app

Each database has a host, a port, a name, and credentials. Find them on your project’s Databases page.

Connection details

From the Databases page, copy the host, port, database name, and user. The password is shown once — store it in your environment variables rather than in code.

Example: connecting to PostgreSQL from Django

DATABASES = {
    "default": {
        "ENGINE": "django.db.backends.postgresql",
        "NAME": "my_database",
        "USER": "my_user",
        "PASSWORD": os.environ["DB_PASSWORD"],
        "HOST": os.environ["DB_HOST"],
        "PORT": os.environ["DB_PORT"],
    }
}

Example: MySQL from Laravel

DB_CONNECTION=mysql
DB_HOST=$DB_HOST
DB_PORT=$DB_PORT
DB_DATABASE=$DB_DATABASE
DB_USERNAME=$DB_USERNAME
DB_PASSWORD=$DB_PASSWORD

Redis

Redis connects the same way with a host and port — perfect for caching sessions and queues.

Security note

Use environment variables for credentials. Never commit database passwords to your repository.
