MultiAgentOS logo MultiAgentOSfor macOS

A native desktop AI agent, built for your Mac.

The macOS edition of MultiAgentOS runs on the shared Avalonia / .NET shell — Apple Silicon and Intel. Bring any LLM, keep your keys in the Keychain, let supervised agents drive your Mac, and run entirely offline with a bundled llama.cpp runtime.

What you get

Everything MultiAgentOS does — at home on macOS.

One native shell that talks to any model, opens sidecars on demand, and acts on your machine under supervision.

1

Bring your own model

Six connection modes: API Key, Local Server, CLI Pipe, OAuth, Terminal, and Local AI — OpenAI, Anthropic, DeepSeek, Ollama, LM Studio, llama.cpp, and on-device GGUF files.

2

Offline by default

A zero-setup bundled llama.cpp runtime means MultiAgentOS works with no internet and no API key — prompts, files, and history stay on your Mac.

3

Keychain security

API keys and OAuth tokens live in the macOS Keychain, never in plaintext on disk. No telemetry, no log files — conversation history is in memory only.

4

Controls your Mac

CGEvent / CoreGraphics desktop control lets the agent move, click, type, scroll, screenshot, and launch apps — every action gated by your approval.

5

Sidecars on demand

Browser, desktop, code editor, terminal, file, and document sidecars open from the same frame when a task needs them, then close again.

6

Supervised subagents

Delegate bounded work with a goal, a tool allow-list, recursion limits, and a turn budget — then hand the result back to the main thread.

Interface details

The same app frame for model setup and file work.

Configure connections, open code sidecars, attach files, and keep the prompt controls visible without jumping between separate apps.

Connection settings

Set up API keys, local servers, CLI pipes, OAuth providers, Terminal templates, and local AI from one sidecar.

Code sidecar

Edit files and folders beside the conversation, with model routing, permissions, and tools still visible.
