I must mention https://ampcode.com/manual which is my favorite toy of them all right now. Has almost no settings; uses Claude 4, no way to change model; just works! (Unfortunately, not a paid comment.)
When Ampcode took it all away from me, I found I enjoyed the actual AI-assisted coding much more than configuring. Of course, largely because it just worked. Granted, I had enough experience with other AI tools to manage my expectations.
