Using Google Antigravity with lite.computer

Google Antigravity is Google's platform for coding agents. Its desktop app is a command center where several agents work at once inside Projects, and the Antigravity CLI, agy, does the same from a terminal.

It suits developers. On a Mac the agents work directly in the local folders and Git checkouts you attach to a Project, so a Showspace added as one of those folders fills up as they write in Local Mode.

Set it up

In lite.computer, click your name at the bottom of the sidebar and open the Agent Helper. Copy the paragraph it gives you and paste it into ~/.gemini/GEMINI.md, which Antigravity reads in every workspace.
In the desktop app, open your Project, click Add Folder and choose your Showspace. When you start the conversation, choose Local Mode so pages save into that folder. For the example below, add your project's folder to the same Project.
Give the Antigravity CLI the app's commands by adding this entry to its settings file. Then run /mcp inside agy to reload the settings and see the server's status.
Keep lite.computer open on your Showspace. Start a new agy session and ask Use the lite.computer tool to list every page in my Showspace. It lists the pages in your folder.

~/.gemini/config/mcp_config.json

{ "mcpServers": { "lite-computer": { "serverUrl": "http://127.0.0.1:48484/mcp" } } }

Use the field name serverUrl, exactly as shown.

Paste into Google Antigravity

Build an interactive dashboard for this project: a chart of commits per week that animates in, the TODO notes in the code in a list you can filter by folder, a tab for each part of the app, and a generated illustration at the top of each tab. Save it as a single self-contained HTML file in my Showspace.

Good to know

We use Google Antigravity with lite.computer ourselves.
Add your Showspace to every Project that should write pages there.
Use the Antigravity CLI setup above when you want to open pages or arrange windows in lite.computer.
Untethered Mobility lets you start a long agent run on your Mac and watch or approve it from your phone. The agent keeps working on your Mac, so pages keep landing in your Showspace.
If you used Gemini CLI with a Google account, the Antigravity CLI is its replacement.
Antigravity creates images while it builds a page. Ask for photos or illustrations in a report or dashboard, and it builds them into the page.

Questions

Does Google Antigravity work with lite.computer?

Yes. Add your Showspace as a folder in a Project, work in Local Mode, and Antigravity saves HTML pages there, which lite.computer shows as they land. One entry in the CLI's settings file lets it open pages and arrange windows in the app as well.

Is Antigravity the replacement for Gemini CLI?

For people who signed in to Gemini CLI with a Google account, yes. Google moved those users to the Antigravity CLI on June 18, 2026. Gemini CLI still works with a Gemini API key, Vertex AI or a Gemini Code Assist license.

Is Google Antigravity free?

Yes. The free Individual plan includes its agent models. Google AI Pro and Ultra plans raise the limits.
