Tower CLI and runtime environment for Tower.

Tower CLI

The Tower CLI is one of the main ways to interact with the Tower environment. You can do basically everything you need inside the Tower CLI, including run your code locally or remotely in the Tower cloud.

Installing the Tower CLI

The main way to install the CLI is using the pip package manager.

$ pip install -U tower

You can also download the CLI directly from one of our releases.

Using the Tower CLI

There are two big components in the Tower CLI reposiory: The CLI itself and the runtime environment for the Tower cloud. We host the runtime in this repository and pull it in to our internal code because we want to ensure that the environments behave exactly the same locally and in our cloud!

Using the CLI

It's pretty straight forward! But here's what it looks like right now.

$ tower

Usage: tower [OPTIONS] <COMMAND>

Commands:
  login    Create a session with Tower
  apps     Interact with the apps that you own

Check Available Features

You can check which features are available in your installation:

import tower
import pprint

# Print information about all features
pprint.pprint(tower.get_available_features())

# Check if a specific feature is enabled
print(tower.is_feature_enabled("ai"))

About the runtime environment

The tower-runtime crate has the Rust library that makes up the runtime environment itself. All the interfaces are defined in the main crate, and the local package contains the invokation logic for invoking tower packages locally.

To learn more about tower packages, see the tower-package crate.

Development

Here are a few handy tips and common workflows when developing the Tower CLI.

Python SDK development

We use uv for all development. You can spawn a REPL in context using uv very easily. Then you can import tower and you're off to the races!

uv run python

If you need to get the latest OpenAPI SDK, you can run ./scripts/generate-python-api-client.sh.
