There is also Cursor Agent CLI which is a TUI exactly like CC. I switched to it because I don't like GUI AI assistants, but I also couldn't stand CC always being overloaded and having many bugs that were affecting me. I'm not on Cursor Agent CLI with GPT5 and happy to have an alternative to CC.
For my personal projects it has completely replaced the need for CC with Anthropic models for me. At work, I am waiting for native Windows support. I don't like using AI assistants via WSL. Since both CA and CC are Node apps and CC has since shipped native Windows support, I don't foresee it taking CA long either. Especially since it can be hacked to work that way today as I've experimented with here: github.com/TomasHubelbauer/cursor-agent-windows
