OSI-licensed only · self-hostable
Red Hat Satellite manages the lifecycle of RHEL systems: content syncing, patch promotion between environments, provisioning and subscription tracking. Satellite itself is a commercial, supported product, but it is built from open-source projects, so you can run the upstream pieces directly without a subscription.
Every tool below is under an OSI-approved licence (GPL-2.0 or GPL-3.0 variants), checked against its repository. Foreman and Katello are the upstream of Satellite, so they are the closest match; Uyuni is a separate stack forked from Spacewalk.
Licences checked against each repository on November 7, 2026.
| Tool | Best for | Licence | Runs as |
|---|---|---|---|
| Foreman | Lifecycle management and provisioning | GPL-3.0-or-later | Server |
| Katello | Content and subscription management for Foreman | GPL-2.0 | Server |
| Uyuni | Systems management across several Linux distributions | GPL-2.0 | Server |
| Pulp | Repository mirroring and content distribution | GPL-2.0-or-later | Server |
| Cobbler | Network installation and PXE provisioning | GPL-2.0 | Server |
| Ansible | Patching and configuration by playbook | GPL-3.0-or-later | Server |
Best for: Lifecycle management and provisioning
A free, open-source project for automating repetitive tasks, deploying applications and managing server lifecycles on-premises or in the cloud. The core of Satellite's provisioning features.
Best for: Content and subscription management for Foreman
A Foreman plugin that syncs content such as packages and container images into versioned sets with staged promotion, and manages subscriptions across large fleets.
Best for: Systems management across several Linux distributions
An open source systems management solution forked from Spacewalk. Manages patching, configuration and provisioning from one console.
Best for: Repository mirroring and content distribution
A free, open-source platform for managing content repositories such as software packages and distributing them to many consumers. Katello uses it for content.
Best for: Network installation and PXE provisioning
A Linux installation server that allows rapid setup of network installation environments.
Best for: Patching and configuration by playbook
A radically simple IT automation system. Playbooks can patch, configure and orchestrate hosts, and are often paired with Foreman.

Quick answers to common questions
Satellite is a supported commercial product. It is built from upstream open-source projects, mainly Foreman and Katello, which you can run without a Red Hat subscription.
Foreman with the Katello plugin, since they supply provisioning and content management respectively.
Uyuni describes itself as a systems management solution forked from Spacewalk. Check its documentation for the distributions supported by your version.
Yes, they are community projects. You lose vendor support and certified content, so you take on testing and maintenance yourself.
Katello's content views and lifecycle environments are built for staged promotion; Uyuni and Pulp offer their own content management features.
List it on TechLogHub and we'll review it for this page.
