Antigravity IDE version information dialog used before updating

Quick answer: To update Antigravity IDE, check the About dialog, close every running copy, and install the verified v2.8.1 package for your architecture or use Google's official download page. On Ubuntu and Fedora, keep the same package-manager or archive path you used originally so you do not create a second installation.

Why Antigravity Says Your Current Version Is Out of Date

An out-of-date warning means the installed desktop client no longer matches the version expected by the service or the current support guidance. Start with the client version and installation path rather than deleting project folders.

The safest update is an in-place install from a verified platform file or the official Google download page. Your projects normally live outside the application directory, but back up important work before changing software.

If the warning returns after an update, check for a stale shortcut, a second installation, a running background process, or a package-manager source that was not refreshed.

Best Update Method by Platform

Choose the update path that matches the original installation. Keep one installation method per machine and verify the About dialog after the update.

Platform Best update method Use this when
Windows Run the verified Windows installer over the existing copy. The new About version is visible and the shortcut opens the same install.
macOS Replace the app in Applications with the matching Apple Silicon or Intel build. The Mac architecture matches the downloaded disk image.
Linux Use the same APT/DNF or tarball path used for the original install. The package source or archive is verified before running it.
Rollback Use an archived version only for a documented compatibility test. The test copy is separated from the daily installation.

How to Update Antigravity IDE Step by Step

Step 1

Check the installed Antigravity version

Open the About dialog and record the version and install path. On Linux, also run uname -m so you can choose x64 or ARM64 correctly.

Step 2

Install the matching verified package

Close Antigravity, use the verified v2.8.1 platform file or the official Google page, and install over the existing copy. Keep the original package route on Linux.

Step 3

Reopen and verify the update

Launch the new executable, check About again, reopen a real workspace, and test sign-in plus one AI feature. If the old version appears, inspect shortcuts and duplicate installations.

What to Do If the Warning Still Appears

If Antigravity still says your current version is out of date after installing the latest version, the issue is usually caused by a stale running process, an old shortcut, or a second installation folder.

Close every Antigravity process before reinstalling

On Windows, check Task Manager for Antigravity processes before running the installer again. On macOS, quit the app from the Dock and Activity Monitor if needed. On Linux, close all Antigravity windows and stop any background process before updating through apt or dnf.

Make sure your shortcut opens the new app

Some users keep an old desktop shortcut, pinned taskbar item, or custom launcher that points to a previous installation path. After updating, open Antigravity from the Start menu, Applications folder, or your system app launcher, then replace old shortcuts if the new app works.

Check whether two versions are installed

A machine can sometimes have a system-wide copy and a user-local copy. If the About dialog still shows an old version, remove the older duplicate only after confirming where your latest installation lives.

Sign in again after a major update

If the editor opens but AI features fail, sign out and sign in again. This helps refresh account state, model access, and cloud feature availability after a client update.

Update Antigravity on Windows

For Windows 10 and Windows 11, download the latest Windows installer, close Antigravity, and run the .exe file. In most cases, installing over the existing copy preserves settings, projects, and shortcuts. If the warning remains, unpin old shortcuts and open the new installation from the Start menu before removing any duplicate copy.

Update Antigravity on macOS

On macOS, download the latest disk image for Apple Silicon or Intel, quit Antigravity, open the .dmg, and replace the app in Applications. If macOS asks whether to replace the existing app, choose replace. Open the app from Applications after updating so you do not accidentally launch an old copy from another folder.

Update Antigravity on Linux

If you installed Antigravity from the Linux repository, update it with your package manager. Debian and Ubuntu users can run sudo apt update and then upgrade or install antigravity. Fedora and RHEL users can run sudo dnf upgrade antigravity. Repository updates are preferable because they keep package metadata and future updates aligned.

Should You Use an Old Antigravity Version?

Old Antigravity versions are useful only for short-term troubleshooting, compatibility checks, or reproducing a project-specific issue. They are not the best default choice because cloud features, agent behavior, security fixes, and model access can depend on the current client.

If you need an old build, record why you are using it, keep the test environment separate from your daily workspace, and return to the latest stable version once the issue is resolved. For most users who see the out-of-date warning, upgrading is safer than downgrading.

Security note

Avoid searches such as Antigravity cracked version, Antigravity APK, or unlimited modified builds. They do not solve update compatibility problems and can put your code, credentials, and workspace files at risk.

Auto-update, Linux package updates, and version-policy choices

Automatic updates are a version-policy choice. If a team pins a release, record the approved version and update window; otherwise, check the official page when the client reports that it is out of date.

Ubuntu and Debian users should refresh package metadata before an upgrade. Fedora and RHEL users should refresh DNF metadata. If the original install used a tarball, replace that tarball rather than adding a second package-manager copy.

If the prompt remains after installing the verified v2.8.1 files, close every Antigravity process, open the About dialog from the new executable, and remove stale shortcuts only after confirming the new path works.

FAQ - Updating Antigravity IDE

How do I update Antigravity IDE?

Check the About dialog, close the running app, then install the verified v2.8.1 file for your platform or use the official Google download page. Verify the version after restarting.

How do I update Antigravity on Ubuntu?

Keep the original package-manager or archive path. Refresh APT metadata before an upgrade, or replace the verified Linux archive with the matching x64 or ARM64 build.

How do I update Antigravity on Fedora?

Refresh DNF metadata if the original installation uses DNF. If it uses an archive, replace that archive instead of adding a second method.

Why does Antigravity still say my version is out of date?

The usual causes are a stale shortcut, a second installation, a running background process, or an unrefreshed package source. Check About from the executable you actually launched.

Do I need to uninstall Antigravity before updating?

Usually no. Install the matching verified package over the current copy. Uninstall only after you confirm that duplicate or damaged installations are causing the problem.

Will updating Antigravity delete my projects?

A normal application update should not delete projects stored outside the app directory. Still, use version control or a backup before a major change.

Can I use an old Antigravity version?

Use an old build only for a documented compatibility test. Keep it separate and do not call it the current release.

How do I update Antigravity CLI?

CLI update intent is separate from this desktop IDE guide. Keep this page focused on the desktop client and use CLI-specific documentation when it is available.
