modal serve

Expose Web Functions with hot-reloading on code changes.

Examples:

modal serve hello_world.py

Modal-generated URLs will have a -dev suffix appended to them when running with modal serve. To customize this suffix (i.e., to avoid collisions with other users in your workspace who are concurrently serving the App), you can set the dev_suffix in your .modal.toml file or the MODAL_DEV_SUFFIX environment variable.

Usage:

modal serve [OPTIONS] APP_REF

Options:

• -n, --name TEXT: Name for this run of the App.
• --timeout FLOAT
• -e, --env TEXT: Environment to interact with. If unspecified, defers to MODAL_ENVIRONMENT, your active local profile, or your workspace default, in that order.
• -m: Interpret argument as a Python module path instead of a file/script path
• --timestamps: Show timestamps for each log line.
• --help: Show this message and exit.
