omar is a TUI for creating powerful agentic organizations.

Lead a team of 100 agents to solve humanity's biggest problems.

omar.tech  •   中文  •     •     •  

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
• One or more coding agents: Claude, Codex, Cursor, Opencode, or Google Antigravity CLI (agy)

One-liner (recommended)

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

Installs all binaries to /usr/local/bin.

Homebrew

brew install lsk567/omar/omar

Build from source

Requires Rust 1.70+ and GNU Make.

git clone https://github.com/lsk567/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 your Executive Assistant (EA) to run a test prompt.

Copy the following into your EA window:

Run https://github.com/lsk567/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.

Supported Agent Backends

Backend	How to launch
Claude Code	omar -a claude (default)
Codex CLI	omar -a codex
Cursor CLI	omar -a cursor
Opencode	omar -a opencode
Google Antigravity CLI (agy)	omar -a agy

Antigravity CLI must be installed and authenticated separately. OMAR does not run the installer automatically; install agy with Google's installer and log in before launching omar -a agy. OMAR launches it with --dangerously-skip-permissions, the CLI's YOLO-style permission mode, and registers an EA-scoped OMAR MCP server as a native Antigravity CLI plugin under ~/.gemini/config/plugins/omar-ea-<id>/ and records it in ~/.gemini/config/import_manifest.json. OMAR creates the plugin files when they do not already exist.

When spawning Codex workers through OMAR's MCP spawn_agent tool, pass backend: "codex", optional model (for example gpt-5.5), and optional reasoning_effort (low, medium, high, or xhigh) to launch native Codex sessions without building raw shell commands.
