Avante - https://github.com/yetone/avante.nvim. Admittedly I haven't had time to keep up with it's changes and as a result have gone back to VS Code + Copilot, but it's very well integrated last I did use it.
I gave Avante a fair try for about a week and my opinion is that it's not really ready for big time yet. Lots of bugs, slow, and cumbersome. Now I just use Claude Code in a separate tmux pane and its great.
