gravity
Command-line utilities to assist in managing Galaxy servers
Decision gist · record as of 2026-08-14
Yes. Gravity is actively maintained, has no known vulnerabilities, carries a permissive MIT license, and solves a real operational problem for Galaxy deployments. Install it if you are running a Galaxy server or managing Galaxy from source; it is already a dependency of Galaxy 22.01+. Low install friction and broad Python version support (3.8–3.14) make adoption straightforward.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later.
- Intended for Galaxy server deployments; most useful when Galaxy is already installed or when managing a Galaxy source checkout.
- Low install friction; pure Python wheel with no compiled dependencies.

What it is and what it does
Gravity is a process manager for Galaxy servers that orchestrates multiple disparate services—web application servers (gunicorn), asynchronous task workers (celery), file upload handlers (tusd), and standalone Galaxy processes—through a unified command-line interface. It provides two main entry points: `galaxyctl` for managing service lifecycle (start, stop, log retrieval) and `galaxy` for running a Galaxy server in the foreground with live log output.
The package abstracts away the complexity of configuring and coordinating these services, supporting both supervisor and systemd as underlying process managers. It reads Galaxy configuration from YAML files, generates appropriate service definitions, and handles process supervision. Gravity is a dependency of Galaxy since version 22.01, though it can be installed independently for use with Galaxy source checkouts or custom deployments.
Use it for
- Start and stop all Galaxy services together using `galaxyctl` rather than managing gunicorn, celery, and tusd individually.
- Run Galaxy in the foreground during development with `galaxy` to see all service logs in real time until interrupted.
- Configure Galaxy services declaratively via YAML and have Gravity generate supervisor or systemd configurations automatically.
- Manage Galaxy server processes on POSIX systems where supervisor or systemd is available as the underlying process manager.
- Deploy Galaxy in production with systemd integration, including memory controls and journald log namespace configuration.

Install
gravity on PyPI
Before you install
Low install friction; pure Python wheel with no compiled dependencies. Active maintenance with recent releases; last commit 2026-08-13. Nine runtime dependencies (Click, supervisor, pyyaml, packaging, pydantic, pydantic-settings, jsonref, requests, requests-unixsocket) are all standard ecosystem packages.
Requires Python 3.8 or later. Intended for Galaxy server deployments; most useful when Galaxy is already installed or when managing a Galaxy source checkout.
