Cline extension can use Grok, in fact I think it's free at the moment. I tried Claude Code and Cline for similar tasks and found Claude Code incredibly expensive but not better, so I've been sticking with Cline and switching between APIs depending on what model currently has the vest price/performance going on.
I wish the Cline extension was more performant. It has a 1000+ ms startup time for VScode and stutters occasionally. In terms of workflow though, it's my absolute favorite. I simply don't think the models are there yet for fully agentic coding in any reasonably complex/novel codebase. Cline lets me supervise the LLM step by step.
