kantoku
Circus is a program that will let you run and watch multiple processes and sockets.
Decision gist · record as of 2026-08-14
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.AI-flagged interpretation of the facts on this page — verify before relying
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.

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
