Where should Antigravity CLI keep running?

Current product change: Google moved individual Gemini CLI users to Antigravity CLI in June 2026. Enterprise and API-key Gemini CLI users follow a different path. Read Google’s announcement
02 · Review the plan

A Terminalbox Shell pane

Choose this only when you need an always-on Linux shell you can reopen in a browser. Antigravity CLI is not preinstalled; install it in the Shell pane after checkout.

  • Terminalbox Base or higher
  • A Shell pane
  • A supported Google account
# In Terminalbox, create or open a Shell pane
# Its tmux wrapper keeps the shell available across browser reconnects

# Download Google's current installer without executing it
installer="${TMPDIR:-/tmp}/antigravity-cli-install.sh"
curl -fsSL https://antigravity.google/cli/install.sh -o "$installer"

# Inspect the script, then run it only when you are satisfied
sed -n '1,220p' "$installer"
bash "$installer"

# Reload PATH and start Antigravity CLI from your working directory
exec "$SHELL" -lc 'cd ~/work && exec agy'

Generated entirely in your browser. No commands or host choices are submitted.

03 · Authenticate remotely

The browser can be on a different device.

In an SSH or browser terminal, launch agy. Google’s manual OAuth flow prints a URL and code. Open the URL on a device with a browser, sign into your eligible Google account, then paste the code into the remote terminal.

04 · Pay only for persistence

Use the host you already have. Buy one only when it removes a real constraint.

€0

Local computer

Use Google’s CLI directly when your machine can remain online and the work belongs there.

Your server cost

Existing SSH server

Use a server you already administer when SSH, patching, isolation, and tmux are already solved.

Antigravity CLI is not preinstalled. After checkout, create a Shell pane and run the reviewed Google installer. Closing the browser leaves the tmux-wrapped shell available; Terminalbox does not change Google’s CLI limits or availability.

05 · Boundaries

Before you choose a host.

Is Antigravity CLI preinstalled by Terminalbox?

No. Choose a plain Shell pane, then review and run Google’s current installer yourself. Terminalbox provides the persistent Linux terminal, not the Antigravity CLI or its Google account access.

How does sign-in work over SSH?

Google’s current CLI supports a manual OAuth flow for remote SSH sessions. The CLI prints a URL to open on a device with a browser and a code to paste back into the remote terminal.

Can I use an API key?

Not with Antigravity CLI’s current consumer sign-in flow. Google tracks API-key support separately, and Google Cloud pay-as-you-go is a different product path. Check Google’s current documentation before choosing an account setup.

Do I need Terminalbox?

No. Use your local computer when it can stay online, or an existing SSH server when you already operate one. Terminalbox is the paid option for an always-on Linux shell you can reopen from a browser or phone.

What keeps running after I close the browser?

The Terminalbox Shell pane is wrapped in tmux, so its shell and processes remain available while the subscription is active. Google account access and Antigravity CLI limits remain separate.
