Unity Antigravity Editor

This package provides native integration between Unity and Antigravity IDE.

It is a fork of the legacy com.unity.ide.vscode package, patched specifically to recognize Antigravity IDE as a supported IDE. This solves the issue where Unity treats the editor as a generic text tool by:

• Automatically detecting Antigravity IDE.exe, Antigravity IDE.app and antigravity-ide paths.
• Forcing the generation of .csproj and .sln files.
• Enabling full IntelliSense support via OmniSharp.

Antigravity 2.0 (Google I/O, May 2026): Antigravity is now two separate apps. The standalone Antigravity app is an agent-orchestration tool with no code editor; Antigravity IDE is the VS Code fork you write code in. Version 1.1.0 of this package only registers Antigravity IDE. See Antigravity 2.0 split if Unity started opening the agent app instead of your scripts.

Important Requirement

Because Antigravity is a VS Code fork, it cannot use the Microsoft "C# Dev Kit". To get IntelliSense working, you must:

1. Install this package in Unity.
2. Install the free-csharp-vscode extension (by muhammad-sammy) inside Antigravity.

Installation

You can install this package directly via the Unity Package Manager using the Git URL.

Unity Package Manager (Recommended)

1. Open your Unity project.
2. Go to Window > Package Manager.
3. Click the + (plus) button in the top-left corner.
4. Select Add package from git URL....
5. Paste the following URL and click Add: https://github.com/TermWay/unity-ide-antigravity.git

Setup

After installing:

1. Go to Edit > Preferences > External Tools.
2. Select Antigravity IDE from the dropdown.
3. Click Regenerate project files.

Antigravity 2.0 split

At Google I/O 2026 (May 19, 2026) Google split the Antigravity product line into two desktop applications that share the same VS Code-fork shell:

Product	What it is	Default location (Windows)	macOS	Linux
Antigravity (2.0)	Standalone agent-orchestration app. Not a code editor.	%LOCALAPPDATA%\Programs\Antigravity\Antigravity.exe	/Applications/Antigravity.app	/usr/bin/antigravity
Antigravity IDE	VS Code fork. The actual code editor. This is what Unity needs.	%LOCALAPPDATA%\Programs\Antigravity IDE\Antigravity IDE.exe	/Applications/Antigravity IDE.app	/usr/bin/antigravity-ide

Versions 1.0.x of this package matched the bare Antigravity executable, which after the split is the agent app. On machines that received the 2.0 update, Unity therefore launched the agent app's home screen on every script double-click.

Since version 1.1.0:

• Only Antigravity IDE locations are discovered. The bare Antigravity app is never listed in the External Tools dropdown.
• A path chosen with Browse... must have an Antigravity IDE file name, and its resources/app/package.json manifest name is verified, so the agent app is rejected even when selected by hand.
• The dropdown entry is named Antigravity IDE (or Antigravity IDE - Insider), never the ambiguous Antigravity.

Upgrading from 1.0.x

1. Update the package in the Package Manager (the Git URL has not changed).
2. Make sure Antigravity IDE is installed. The 2.0 agent app cannot be used as a code editor.
3. If your External Script Editor was still set to the bare Antigravity app, the package switches it to Antigravity IDE automatically on the next domain reload and logs a message in the Console. If Antigravity IDE cannot be found, a warning is logged instead: install it and select Antigravity IDE in Edit > Preferences > External Tools.
4. Double-click a C# script. It should open in a window titled Antigravity IDE.
