Aider. I tried Cursor too, but I don't like VS Code and not being able to chose the LLM provider. I think there are already a lot of tools that perform kind of equally.
What do you mean? You can chose the LLM in Cursor. (I don't like VSCode either, but unfortunately Cursor is best for the rest of the UX; I find myself using Cursor for the prompt-based part of the work, and then move to IntelliJ to do "my" part of the coding)
