KilnCoding tools split into three shapes: plugins that live in an editor you already use, AI-native IDEs, and terminal agents that walk a whole repository. The useful question is not which logo is smartest on a leaderboard. It is whether you want tab completion, multi-file edits, or long unattended refactors. We exclude cracked IDEs and “unlimited Pro for free” mirrors.
