SpaceO

Give AI agents their own screen on your Mac.

Let agents work in real apps while you keep using your computer. SpaceO runs agent apps on separate, headless displays.

Recorded from the real SpaceO Viewer using synthetic preview sessions and sample screen content. View the still screenshot.

[!NOTE] Latest release · latest signed SpaceO release. Install it with one command, which verifies the signed, notarized release for you. You can also download the DMG from the Releases page.

Supported scope: native apps and Chromium browsers. Managed Electron apps such as Cursor and VS Code are refused before launch because they can take desktop focus. These editors can still connect to SpaceO as MCP clients to drive supported apps.

A screen for every agent

You keep working	Your agents keep working
Your physical display stays available	Apps render on headless virtual displays
Your pointer stays where you put it	Accessibility actions and targeted events operate apps
You decide when to intervene	Viewer shows sessions, activity, pause, and human handoff
Multiple agents can share one Mac	Sessions own apps, windows, and display tiles

SpaceO is a native Swift app, a CLI, and an MCP server. Agents can read interface elements, click controls, enter text, inspect screenshots, and check what actually happened. Sessions can use dedicated displays or share a display in separate tiles.

What an agent can do

Capability	MCP tools
Own a workspace	spaceo_session_create, spaceo_session_destroy, spaceo_session_list, spaceo_pool_status, spaceo_pool_trim
Launch and place apps	spaceo_open_app, spaceo_open_url, spaceo_adopt_app, spaceo_place_window, spaceo_list_windows
See the interface	spaceo_read_screen, spaceo_find, spaceo_read_text, spaceo_screenshot, spaceo_wait_for
Act on it	spaceo_click, spaceo_type, spaceo_press_key, spaceo_scroll, spaceo_drag, spaceo_menu, spaceo_select_text
Batch and verify	spaceo_run_steps, spaceo_verify_isolation, spaceo_events
Hand off to you	spaceo_session_pause, spaceo_session_resume, per-session clipboard broker

Actions prefer Accessibility elements over coordinates, and every receipt says whether the result was confirmed, unconfirmed, or refused. The reference lists every tool and CLI command.
