Incus is a manager for system containers, application containers and virtual machines. Administrators run containers and VMs side by side on shared storage and networks and manage them through a command-line client or a single REST API, on anything from one machine to a cluster. The code is written in Go and released under the Apache 2.0 licence. Incus is installed on your own Linux servers; upstream does not ship packages, so they come from Linux distributions or third-party repositories.
Incus started as a community fork of LXD after Canonical decided to take LXD away from the Linux Containers project, which adopted Incus and hosts it as a community-led alternative. No single vendor owns it. Zabbly, a company based in Canada, offers commercial support and packages and sponsors the project infrastructure. Because you operate Incus yourself, workloads and data stay wherever you run it, including EU data centres, and no vendor-run cloud service is involved. The open source code can be audited, and support is available from the community or from Zabbly.
