Sites
Databases
MariaDB and PostgreSQL databases linked to your sites.
Install MariaDB or PostgreSQL from the server's Databases section, then create databases and users.
Link a database to a site
Open the site and choose Database. Linking creates the database and a user for the site and writes the connection details into the app's environment (DB_HOST, DB_DATABASE, DB_USERNAME, DB_PASSWORD, DATABASE_URL). Containers reach the database on the host too.
Object cache
Install Valkey to give PHP sites a fast object cache; turn it on per site under Caching and protection.
Backups and transfers
Databases are part of backups. You can also export, import and copy a database to another server from the panel.
