Z.ai documents integrations with nearly all the popular CLI-based agents: https://docs.z.ai/devpack/tool/others
If you're already used to your TUI coding agent, you don't need the desktop agent. Although it is nice that it is there for folks who prefer the Codex App/Claude App UI approach.
Also, kudos to the Z.ai team for adding Linux support from day one.

Yeah, I use GLM 5.2 in OpenCode, running in a Docker container with CodeNomad as the web-based GUI. It works perfectly; I can access it from anywhere, and it runs all models (except for Anthropic's subscriptions).
