What no installer tells you is what still runs on another company's machine afterwards: the sandbox the agent works in, the images it pulls, the model calls it makes. Kortix is the open-source AI Operating System. Its self-host docs set out each of those. https://aimarketingagentsguide.com/deskferry-alternative 2026-10-26T00:00:00Z
