antigravity-nix

Auto-updating Nix Flake for Google Antigravity — zero configuration, multi-platform, version-pinned.

What This Provides

• Three Components: Packages for Antigravity 2.0 (Base App), Antigravity IDE, and Antigravity CLI (agy).
• FHS environment wrapping the upstream GUI binaries with all required libraries.
• Automated updates via GitHub Actions (daily at 0700 UTC), with hash verification and build testing.
• Multi-platform: Linux (x86_64, aarch64) is built and verified in CI. macOS (x86_64-darwin, aarch64-darwin) packages are provided and evaluate, but are experimental and currently untested — see [macOS]!(#macos-experimental).
• Version pinning through tagged releases for reproducible builds.

Migrating from Antigravity 1.x

Antigravity 2.0 (May 2026) split the product into three packages, and this flake’s defaults changed to match:

• default / google-antigravity is now the standalone Antigravity 2.0 app (agent orchestration), not the IDE. In the 1.x flake this attribute was the IDE.
• The IDE is now google-antigravity-ide (antigravity-ide on PATH). It remains available, but Google is steering users toward the 2.0 app, so treat it as legacy.
• The CLI (agy) is new — it is the successor to the Gemini CLI.

If your config referenced google-antigravity / google-antigravity-no-fhs expecting the IDE, switch to google-antigravity-ide / google-antigravity-ide-no-fhs. Because this flake pins versions, you upgrade on your own schedule (nix flake update antigravity-nix) — unlike the upstream app, an update here can never silently replace your IDE.

Quick Start

Run the Antigravity Base App (default):

nix run github:jacopone/antigravity-nix

Run the Antigravity IDE:

nix run github:jacopone/antigravity-nix#google-antigravity-ide

Run the CLI tool (agy):

nix run github:jacopone/antigravity-nix#google-antigravity-cli

Installation

NixOS Configuration

Add to your flake.nix:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    antigravity-nix = {
      url = "github:jacopone/antigravity-nix";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, nixpkgs, antigravity-nix, ... }: {
    nixosConfigurations.your-hostname = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        {
          environment.systemPackages = [
            antigravity-nix.packages.x86_64-linux.default # Base App
            antigravity-nix.packages.x86_64-linux.google-antigravity-ide # IDE
            antigravity-nix.packages.x86_64-linux.google-antigravity-cli # CLI
          ];
        }
      ];
    };
  };
}

Home Manager

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    home-manager.url = "github:nix-community/home-manager";
    antigravity-nix = {
      url = "github:jacopone/antigravity-nix";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, nixpkgs, home-manager, antigravity-nix, ... }: {
    homeConfigurations.your-user = home-manager.lib.homeManagerConfiguration {
      pkgs = nixpkgs.legacyPackages.x86_64-linux;
      modules = [
        {
          home.packages = [
            antigravity-nix.packages.x86_64-linux.default
            antigravity-nix.packages.x86_64-linux.google-antigravity-ide
            antigravity-nix.packages.x86_64-linux.google-antigravity-cli
          ];
        }
      ];
    };
  };
}

Overlay

{
  nixpkgs.overlays = [
    inputs.antigravity-nix.overlays.default
  ];

  environment.systemPackages = with pkgs; [
    google-antigravity
    google-antigravity-ide
    google-antigravity-cli
  ];
}

Package Variants

For the GUI applications (google-antigravity and google-antigravity-ide), two packaging strategies are available:

Variant	Strategy	Trade-off
default / google-antigravity	buildFHSEnv + bubblewrap	Sandboxed, but inherits no_new_privileges restrictions
google-antigravity-no-fhs	autoPatchelfHook	No sandbox, full system integration

The default uses buildFHSEnv to create an isolated FHS environment via bubblewrap. This is the most compatible approach, but the sandbox sets the kernel’s no_new_privileges flag, which prevents privilege escalation (sudo, pkexec) and can cause issues with nested namespaces.

The no-fhs variant uses autoPatchelfHook to patch ELF binaries directly, the same approach used by VS Code in nixpkgs. It runs natively on NixOS without sandboxing.

# Use the no-fhs variant
home.packages = [
  antigravity-nix.packages.${system}.google-antigravity-no-fhs
];

Or via override:

google-antigravity.override { useFHS = false; }

Chrome Profile Isolation

By default, Antigravity GUI apps use your system Chrome profile (~/.config/google-chrome), giving access to your installed extensions. To run with an isolated Chrome profile instead (e.g., when testing untrusted apps):

google-antigravity.override { useSystemChromeProfile = false; }

This omits the --user-data-dir and --profile-directory flags, letting Chrome manage its own profile independently. Works with both FHS and non-FHS variants.

Usage

antigravity                  # launch Antigravity Base App
antigravity-ide              # launch Antigravity IDE
agy                          # use the Antigravity CLI

Version Pinning

# Follow latest (recommended)
inputs.antigravity-nix.url = "github:jacopone/antigravity-nix";

# Pin to a specific release
inputs.antigravity-nix.url = "github:jacopone/antigravity-nix/v2.0.3-6242596486512640";

Update to the latest version:

nix flake update antigravity-nix

All releases: https://github.com/jacopone/antigravity-nix/releases

Troubleshooting

IDE Freezes on Close (Known Upstream Issue)

The Antigravity IDE currently has a known bug across all Linux distributions (not just NixOS) where it may freeze the system upon closing. As a workaround, you can force-kill the process immediately after closing the window to prevent the freeze (do not run this before closing, or your work may not be saved):

pkill -9 -f antigravity-ide

fetchurl fails or hash mismatches

If the default fetchurl path fails — Google CDN unreachable, regional restrictions, hash drift after an upstream republish, corporate firewall — you can supply the tarball locally via srcOverride:

1. Download the respective tarball from Antigravity.
2. Point the package at it:

(antigravity-nix.packages.${system}.default.override {
  srcOverride = /absolute/path/to/Antigravity.tar.gz;
})

This bypasses fetchurl while keeping the rest of the packaging (FHS wrapping, Chrome integration, desktop entry) intact. No --impure and no patching required. Works for both the default and no-fhs variants.

Requirements

• Nix with flakes enabled
• allowUnfree = true (Antigravity is proprietary software)
• On aarch64-linux, Chromium is used automatically since Google Chrome is unavailable

macOS (experimental)

The darwin packages (x86_64-darwin, aarch64-darwin) evaluate and fetch the official macOS builds, but are untested — CI builds and verifies Linux only. The CLI (agy, a plain binary) is the most likely to work; the GUI apps copy the .app into $out/Applications without code-signing or quarantine handling and may not launch cleanly. Reports and fixes from macOS users are welcome.
