Where Does Google Antigravity Store Settings and Extensions?
Antigravity IDE settings, extensions and agent data folders on Windows, and the 2.0 folder split to watch for.
Last updated
Antigravity is built on VS Code, so settings and extensions live in the familiar Roaming and home-directory spots. Backing up two folders preserves the whole setup.
Watch for the product-name split: newer Antigravity IDE builds read from Antigravity IDE folders while older installs used Antigravity. A missing setup after an update usually means files sit in the other folder, not that they are gone.
Where Antigravity stores this, by platform
%APPDATA%\Antigravity
Holds the User folder with settings.json and keybindings. Extensions live separately at %USERPROFILE%\.antigravity\extensions. Newer IDE builds use %APPDATA%\Antigravity IDE and %USERPROFILE%\.antigravity-ide instead, so copy between the pair when migrating. Agent artifacts also land under %USERPROFILE%\.gemini\antigravity.
Frequently asked questions
Antigravity lost my settings after updating. Where are they?
They are almost certainly in the other product folder. Copy %APPDATA%\Antigravity into %APPDATA%\Antigravity IDE, and .antigravity extensions into .antigravity-ide, with the IDE closed.
How do I back up Antigravity completely?
Copy the Roaming settings folder plus the .antigravity extensions folder. Those two cover settings, keymaps, extensions and chats.
