There is a VS Code extension for Claude Code. It's hardly more than a terminal window really, but that in itself is pretty handy. If you do /ide to connect up the extension it does a few things, but not yet anything resembling the Cursor diff experience (much less the Cursor tab experience, which is the reason I still use it).
Claude Code has pretty much replaced Copilot overnight for me, though I wish the VS Code plugin was a bit more integrated, as it's only a little bit more than a terminal, though I guess that's the point. I was hoping for syntax highlighting to match my editor and things like that (beyond just light/dark theme).
What I'd really want is a way to easily hide it, which I did quite frequently with Copilot as its own pane.
I use Claude Code 50% of times with Cursor now due to the diff and tab. The extension is just a bit buggy sometimes otherwise I would use it much more. I hit some node related bugs today while searching stuff with it (forgot to report to Anthropic lol). Other bugs include a scroll stuttering.
