I like the terminal UX because VS Code (and any forks of it) is not my editor of choice, and swapping around to use an editor just for AI coding is annoying (I was doing that with the Zed Assistant a lot).
With Claude Code I can stay in Goland, and have Claude Code in the terminal.
You could also try JetBrains' Junie and Sourcegraph Cody.
windsurf also have plugins to jetbrains - they rebranded the whole company from codeium to windsurf and their jetbrains plugin also support cascade.
I was very unimpressed with their original AI assistance implementation, so I’m gonna wait to see some user stories / reviews before I put my time into that, and so far I have seen effectively no mention of Junie anywhere.
Moreover, there’s no way to bring your own key, with the highest subscription tier being $20 per month flat it seems, which is the cost of just 1-3 sessions with Claude Code. Thus, without evidence to the contrary, I’m not holding my breath for now.
