A macOS desktop app for running Claude Code sessions in parallel. Native Electron shell with persistent sessions, drag-and-drop reordering, themes, and auto-updates.
Download the latest .dmg from Releases, open it, and drag Codez to Applications.
Codez checks for updates automatically and will notify you when a new version is available.
- macOS (Apple Silicon)
- Claude Code CLI installed and authenticated — install guide
Codez wraps the Claude Code CLI in a native app with session management. Each session is a full Claude Code conversation running in its own PTY (terminal emulator), so you can run multiple agents in parallel across different repos.
- Parallel sessions — run multiple Claude Code conversations side by side
- Persistent history — sessions survive app restarts; resume where you left off
- Drag-and-drop reordering — organize sessions manually in the sidebar
- Session archiving — archive finished sessions, restore them later
- Themes — 6 built-in themes (3 dark, 3 light)
- Custom app icons — 9 icon variants to choose from
- Keyboard shortcuts — Cmd+1..9 to jump between sessions, customizable bindings
- Auto-updates — notifies when new versions are available on GitHub Releases
- Voice input via local Whisper STT
- Git worktree isolation per session
- File diff review before committing
- Additional agents (Gemini CLI, Mistral Vibe)

Claude Code runs in -p (pipe) mode — each turn spawns a process that streams NDJSON events and exits on completion. Multi-turn conversations use --resume to continue the session.
