I also highly suggest OpenCode. You'll get the same Claude Code vibe.
If your computer is not beefy enough to run them locally, Synthetic is a bless when it comes to providing these models, their team is responsive, no downtime or any issue for the last 6 months.
I've also made decent experiences with continue, at least for autocomplete. The UI wants you to set up an account, but you can just ignore that and configure ollama in the config file
For a full claude code replacement I'd go with opencode instead, but good models for that are something you run in your company's basement, not at home
