Antigravity accounts

Agent Switch keeps several Antigravity accounts signed in at once, so agy starts on the right account for each project without signing out and in again.

Antigravity support is narrower than for Claude Code and Codex. Antigravity reports no usage numbers that Agent Switch can read, so everything built on usage (balanced starts, limit protection, suggestions) does not apply. Folder pins and a preferred account work fully.

Turn it on

Antigravity is off by default, so the desktop app does not show it. Turn it on in Settings › Providers, or from the CLI:

agent-switch providers enable --provider antigravity
agent-switch providers status

The CLI commands accept --provider antigravity either way. If agy is not on your PATH, point Agent Switch at it:

agent-switch providers link --provider antigravity --path ~/.local/bin/agy

How the accounts stay apart

agy keeps its settings under your home folder, so each Antigravity account gets its own home: ~/.agent-switch/antigravity/<name>/config. The agy shell wrapper sets HOME to that folder before it starts the real agy.

On macOS, agy also stores its login in the keychain, always under the same name. Agent Switch therefore gives each account its own keychain file inside its folder. The password of that keychain is kept in your login keychain under an anonymous name. Your own agy login is not touched. agent-switch doctor checks these keychains.

Caution

Because HOME points at the account’s folder, programs that agy starts see that folder as their home too, not your real one.

Add your accounts

1. Add the account. agy has no separate login command, so Agent Switch starts agy itself in the new account’s folder. Sign in there when it asks.

   agent-switch add work --provider antigravity

2. Do the same for every other account.

   agent-switch add personal --provider antigravity

3. Turn on the shell wrapper, if you have not yet, and open a new terminal.

   agent-switch shellenv install

To sign an account in again later, run agent-switch login work --provider antigravity; it starts agy the same way. Use add, not import: there is no Antigravity login file that import could copy.

Choose which account agy uses

Without usage numbers there is nothing to balance, so a plain agy start uses your preferred Antigravity account:

asw antigravity work

Pin a folder to an account, and agy started there always uses it:

cd ~/code/client-a
agent-switch map client-a --provider antigravity

Or start one session on a given account:

agent-switch run personal --provider antigravity

Pools add nothing for Antigravity: a pool chooses by usage, and there is none to compare.

Account identity macOS

Agent Switch reads which Google account an Antigravity account is signed in to from its keychain, so the email shows up in list, status and the app. This works on macOS only. On Linux and Windows, Antigravity accounts work but show no email.

What works and what does not

Works	Does not work
Separate accounts, each signed in	Usage readout and meters
The agy shell wrapper and run	Balanced starts and pools
Folder pins and a preferred account	Limit protection and limit suggestions
disable, enable, label, color, rename, remove	Sessions, takeover and handoff
Opening the Antigravity app per account (macOS)	One account, one session (the guard)
	rebind, share, keep accounts signed in

The Antigravity app macOS

On macOS, Agent Switch can open the Antigravity desktop app as a specific account, each with its own browser data, so two accounts can run side by side:

agent-switch open antigravity work
agent-switch launcher add antigravity work
