# kantoku — Circus is a program that will let you run and watch multiple processes and sockets.

License: permissive · Maintenance: aging · Downloads: 142.8K/mo

## What it is and what it does

Kantoku is a process and socket manager that lets you run, monitor, and control multiple processes simultaneously. It can be used as a Python library or invoked from the command line, making it suitable for both programmatic and operational workflows. The package depends on psutil for system monitoring, pyzmq for inter-process communication, and tornado for async I/O.

The package is marked Production/Stable and supports Python 3.7 through 3.13 across Linux, macOS, and Windows. The repository remains active and is not archived, though it carries an aging maintenance status.

Use it for:

- Supervise and restart multiple worker processes in a long-running application
- Monitor system resource usage of managed processes via psutil integration
- Coordinate inter-process communication through ZeroMQ socket management
- Run batch jobs or background tasks with centralized lifecycle control

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Kantoku runs and watches multiple processes and sockets, providing process lifecycle management and monitoring through a library or command-line interface.

Yes, with conditions. Kantoku is low-friction to install and permissively licensed. It is suitable if you need straightforward process supervision and monitoring. However, the aging maintenance status warrants checking whether the project meets your long-term support expectations before adopting it for new critical systems.

## Install

pip install kantoku
uv add kantoku
poetry add kantoku

## Installing kantoku

Before you install: Low install friction with pure-Python dependencies (psutil, pyzmq, tornado). The package is in aging maintenance status with the repository remaining active and the codebase marked Production/Stable.

License in practice: Licensed under Apache Software License (permissive), allowing commercial and private use with minimal restrictions.

Quickstart:

pip install kantoku

import kantoku
# Use kantoku to manage and monitor processes

Verify before relying:

- Whether kantoku is actively maintained or in maintenance-only mode despite aging status
- Specific process management capabilities and API surface compared to alternatives
- Real-world deployment patterns and typical use cases in production environments
- Why the last release was 521 days ago and what that means for stability
