The plugin just opens a terminal whereas in Zed you get a more natively feeling experience. In JetBrains they do support it as one of their agents but now you have to buy into JetBrains AI credit system instead of just using your Claude subscription.

Theres two ways to use Claude Code in JetBrains and instead of helping them make their plugin better they opted to try and make money off of it. Which Zed could have done the same but instead lowered their monthly to let you use your own Claude Code subscription.
