Subscription Management:
Particular upstream and downstream versions may include integration to supported vendor subscription support network such as Red Hat Subscription Management (RHSM), ULN, and SUSE Enterprise Linux Server subscriptions.
Backend Database:
While formerly requiring the commercial Oracle Database as a backend, version 1.7 (released in March 2012) added support for PostgreSQL.
Upstream and downstream versions
A number of DownStream versions use upstream Spacewalk version as the basis of their System Provision, patch and errata management:
Support for particular client OSes, server OSes, system architectures, backend databases, and subscription services varies between versions and releases.
Oracle Spacewalk
Oracle introduced their own version of Spacewalk particularly to provide a familiar alternative for those switching from a different vendor while Oracle Enterprise Manager remains Oracle Corporation's preferred way of managing systems.
Spacewalk for Oracle® Linux is designed to be hosted on Oracle Linux (OL).

Red Hat Satellite 5 is a licensed downstream adaption of Spacewalk with added functionality to manage Red Hat Enterprise Linux Subscriptions. In the active years of the Red Hat Satellite 5 lifecycle Spacewalk was simply known as the upstream project for Satellite. The relationship between Spacewalk and Red Hat Satellite 5 was analogous to the relationship between Fedora and Red Hat Enterprise Linux. With the emergence of Red Hat Satellite 6 with based on a fundamentally different toolset, end of lifecycle phase of Red Hat Satellite 5 and the emergence of downstream spacewalk based offerings from Oracle and SUSE newer versions of Spacewalk may not have this close relationship.
In May 2018, during the openSUSE conference in Prague, it was announced that a fork of Spacewalk, called Uyuni, was being created. Named after the salt flat in Bolivia, Uyuni uses Salt for configuration management and React as the user interface framework.
From version 4.0, SUSE Manager is based on Uyuni as its upstream project.
History and development
Development
Red Hat developed the Red Hat Network to manage subscriptions software management and created the Red Hat Satellite application as a central management point with the user network.
For Red Hat Satellite version 5 the Satellite Function was implemented by a toolset named Project Spacewalk.
Red Hat announced in June 2008 Project Spacewalk was to be made open source under the GPLv2 License
Satellite 5.3 was the first version to be based on upstream Spacewalk code.
Stewardship and governance
In the Spacewalk FAQ issued in 2015 after the release of Red Hat Satellite 6 Red Hat.
Red Hat formally released Spacewalk as open source(GPLv2) in June 2008
Red Hat continues to sponsor and support Spacewalk as the upstream Red Hat Satellite 5. However that participation is anticipated to diminish as Red Hat Satellite 5 enters the final phases of its lifecycle. Spacewalk is not and can never be upstream for Red Hat Satellite 6 released in September 2014 due to it being a ground up rebuild with a different toolset.
The Spacewalk project can continue to grow and flourish provided that the community continues to find it a useful tool and is willing to support it.
Satellite 5 went end-of-life on 31 May 2020, the Spacewalk project was discontinued at the same time.

Criticisms
In a 2019 paper considering Linux open-source patching tools, Spacewalk was commended for having a software inventory and community support but limited support for distributions; notably, Ubuntu was an issue.
