Features

Deep hierarchies

Agents managing agents, just like a company. Create parallel organizations of arbitrary depth.

Heterogeneous backends

Let Claude, Codex, Cursor, Opencode, and Google Antigravity collaborate as a team. Mix and match the best model for each task.

Full control

Talk to and control any subagent you want. Navigate hierarchies with arrow keys and attach via popup.

Flexible lifespans

Long-running or ephemeral agents, your choice. Persistent state across sessions with memory snapshots.

Messaging & integrations

Connect agents to Slack channels. Bridge the gap between human and AI workflows seamlessly.

Built on tmux

Supports all tmux commands and key bindings. Highly customizable with battle-tested session management.

Launch Mission Control

$ omar serve --ui

Opens the web UI in your browser. Describe a workflow, confirm the program it drafts, and watch the run on a live diagram.

Or drive it from the terminal

$ omar

The same runtime in tmux. Copy a prompt into your Executive Assistant window and watch agents spawn.
