What is MultiAgentOS?

MultiAgentOS is a local-first desktop AI agent app for Mac and Windows. It brings local models, API providers (OpenAI, Anthropic, DeepSeek, xAI, Google, Mistral), files, screenshots, MCP tools, commands, supervised subagents, and desktop actions into one visible Avalonia workspace.

Does MultiAgentOS support local models and Ollama?

Yes. MultiAgentOS supports local model workflows through dedicated Local Server and Local AI connection modes. It works with Ollama, LM Studio, llama.cpp, GPT4All, vLLM, and any compatible local server, plus on-device GGUF model files.

Is MultiAgentOS subscription software?

No. MultiAgentOS is sold as a one-time license. Founder pricing is $79 for the first 200 buyers, with a 14-day money-back guarantee.

Is MultiAgentOS a good Cursor alternative?

MultiAgentOS is a desktop AI agent rather than an IDE. It is a strong Cursor alternative when you need local-first model routing, MCP tools, supervised subagents, desktop actions, and a workflow that runs beside your editor instead of inside it.

Does MultiAgentOS support MCP (Model Context Protocol) servers?

Yes. MultiAgentOS includes first-class MCP server configuration with least-privilege defaults. You add MCP servers, choose which tools to expose, and the agent can call them under supervision.

Can I run MultiAgentOS fully offline?

Yes. With local server (Ollama, LM Studio) or local GGUF models, MultiAgentOS runs entirely on your machine. Prompts, files, credentials, and run history stay on your device unless you choose to send them to an API.

What operating systems does MultiAgentOS support?

MultiAgentOS runs on macOS 14 or later and Windows 10 or later. It is built on Avalonia for a native shared shell on both platforms.

How does MultiAgentOS handle privacy?

MultiAgentOS is designed local-first. Your prompts, files, credentials, and run history stay on your machine unless you explicitly send them to a cloud provider. Tools and computer actions require approval, and you decide what each agent can see and do.

Runtime Tool Surface current

Gives each model a focused tool set, then opens browser, desktop, code, terminal, and subagent sidecars when the workflow needs them.

Learn how it works

25 core prompt tools
Model routes to sidecars and runtimes
5 packs Windows on-demand categories
Subagents bounded delegated work

Live agent automation

Watch the agent move from prompt to action.

MultiAgentOS is built around visible, supervised automation: prompt the agent, let it operate an in-app browser session, or hand it a desktop workspace while you keep using your own computer.

Prompt the agent

Give the LLM a task, context, and permission boundaries before it acts.

Full workspace remains visible
Model and route controls stay in the prompt bar
Supervised approval gates sensitive actions

Run the browser agent

The LLM opens a live browser session, reads pages, clicks, types, and reports status.

Opens from the same app frame
Reads, clicks, types, and reports progress
Human stop and review controls stay available

Use the in-app desktop

Give the agent a visible desktop workspace while your normal desktop stays yours.

Runs inside an app-contained workspace
Keeps task context beside the prompt
Your normal desktop stays separate

Use the AI stack you already trust.

Cloud models, local engines, command-line tools, secure providers, and on-device files all meet in the same Avalonia desktop shell.
