LLM agents are unpredictable. Their coordination doesn't have to be.

omar delivers deterministic, formally specified orchestration for multi-agent systems.

Terminal UI

Features

• Deep hierarchies: Agents managing agents, just like a company.
• Heterogeneity: Let claude, codex, and other agents collaborate as a team.
• Full control: Talk to and control any subagent you want.
• Life span: Long-running or ephemeral agents, your choice.
• Customization: Support all tmux commands you love.

Other features include messaging systems integration (e.g., Slack), computer use, and more.

Installation

Prerequisites

• tmux 3.0+
• Rust 1.70+
• GNU Make
• Node.js 22.13+ (to build Mission Control, which make build embeds)
• One or more coding agents: Claude, Codex, Cursor, Opencode, or Google Antigravity CLI.

One-liner (recommended)

curl -fsSL https://omar.rs/install.sh | sh

Installs all binaries to /usr/local/bin.

Homebrew

brew install omar-os/omar/omar

Build from source

Requires Rust 1.70+ and GNU Make.

git clone https://github.com/omar-os/omar.git
cd omar && make install

Quick Start

Step 1: Launch omar

$ omar

Go here to see how to launch with specific agent backends.

Step 2: Tell the Executive Assistant (EA) to run a test prompt.

Copy the following into the EA window:

Run https://github.com/omar-os/omar/blob/main/prompts/tests/project-factory.md

You should see agents being spawned by the EA.

Tip: Use ↑↓←→ to cycle through agents at the current level. Use Tab to drill into a deeper level. Use Shift+Tab to back out.

Step 3: Shutdown the project.

Go back to the EA and type in:

Shutdown the test project and its agents.

Mission Control

The web client for authoring and observing topology programs lives in web/, and is built from this same commit as the runtime it talks to.

If you installed omar, it is already in the binary:

omar serve --ui

Serves Mission Control from the daemon's own address and opens a browser. The page and the API share an origin, so there is nothing to point at anything.

Working on the client itself, use the dev server instead — it reloads:

make dev

Builds the runtime, starts the daemon, starts Mission Control pointed at it, and opens a browser. Ctrl-C stops both. Needs Node.js 22.13+; see web/README.md.
