// ENVIRONMENT AND SECRETS
System Environment Variables
The `DATABASE_URL` and `PORT` variables AnySites injects automatically.
Two environment variables are set automatically for every container project and cannot be edited or deleted:
| Variable | Value |
|---|---|
DATABASE_URL | The project's provisioned Postgres connection string — see Connect to DATABASE_URL. Only present if the project has a database. |
PORT | The port your app is expected to listen on — matches the port set in project settings, and is what the deploy health check probes. |
Static sites don't get either — there's no running process and no database by default.
