AionUi is a strong ai agent platform (Free / open-source). Tandem comes at the same problem from a different angle: a local-first fleet you orchestrate across every project — spawn agents into isolated worktrees, review and merge them from one inbox, and keep your code on your hardware or run it in our managed cloud. The matrix below scores the two on 82 shared dimensions.
