Why kmux?
Running CLI-based AI agents like Claude Code, Codex CLI, or Antigravity CLI alongside your development server quickly leads to terminal clutter, fragmented session history, and git conflicts when agents write to the same working directory.

kmux solves this by providing a dedicated terminal workspace built for agent workflows:

- Isolated Parallel Sessions: Run multiple agents simultaneously in split panes or vertical tabs without environment conflicts.
- Attention Notifications: Get native desktop notifications and workspace badges immediately when an agent completes a task or requires human input.
- Unified Usage Dashboard: Monitor API spend, token heatmaps, and session budgets across all agent providers in a single sidebar.
- Instant Session Resume: Browse your indexing history and resume past agent sessions in one click.
- Worktree Workspaces: Spin up isolated git worktree environments automatically, allowing multiple agents to safely modify different branches of the same repository.
