You can use Cursor CLI, it's a terminal agent, just like Claude Code and Codex. I use it sometimes, I haven't opened the actual Cursor IDE in ages.

The potential benefit of Cursor CLI (vs CC and Codex) is that you can easily between all major models (by Anthropic, OpenAI, xAI, as well as Kimi K3 and GLM 5.2). I found it useful when reviewing work - e.g. I implement using Opus then review using Sol, etc. Models by different providers tend to have different perspective on things and they can find different issues with the code.

Zed lets you use Claude Code, Codex, OpenCode, etc. all through the same UI. Like you, I use that to cross validate using models from different providers and switch over to GLM 5.2 when I exceed my Claude Code limit.
