Antigravity Remote Control: Use It From Your Phone
Antigravity has no phone app and no first-party way to steer a local coding session from one. Google's own Antigravity 2.0 announcement lists remote control and cloud-deployed agents among the things still to come. The working path today is a third-party one. Install the Grok Build for VS Code (Community) extension from Open VSX, which is Antigravity's own extension gallery, then pair it with AFK Pilot. You pair once with a one-time code, and after that you can chat, watch the work stream, approve permission prompts, and edit project files from a browser on any device. It works on Antigravity 2.1.1 and newer.
One thing up front, because it decides whether the rest of this page is useful to you. This does not remote-control Antigravity's own built-in agent. It runs the Grok Build agent inside Antigravity, and that agent is the one you steer from your phone.
I built AFK Pilot, and I also build the extension it connects to. Neither is affiliated with or endorsed by Google or SpaceXAI (formerly xAI).

At a Glance
What it is. Remote control for a coding agent running inside Antigravity, from a phone or any browser.
Which agent. The Grok Build agent, running in the Grok Build for VS Code (Community) extension. Not Antigravity's own agent.
Editor. Antigravity 2.1.1 or newer. That build reports VS Code base 1.107.0, which clears the extension's 1.106 floor.
Where you install it. Open VSX, Antigravity's extension gallery.
Runs on. Any modern browser. Installable as a phone app (PWA).
Setup. Pair once with a one-time code. No tunnels, no config.
Agent account. Free to try with usage limits on any X or Grok account. SuperGrok, X Premium+, or an xAI API key for sustained use.
Free tier. 1 linked device, 100 remote messages a week, the full chat UI.
Paid. Remote Max, $5 a month, for unlimited linked devices and unlimited remote messages.
What Antigravity Itself Offers Remotely
Nothing yet, and Google says so. Antigravity 2.0 is a standalone desktop application for macOS, Windows, and Linux, and its agent runs in one of two modes, Local Mode in your open folders or New Worktree Mode in an isolated Git worktree, both on your machine. There is no remote development surface, no tunnel, and no companion app. The 2.0 announcement closes by promising remote control and cloud-deployed agents as future work, which is the clearest possible statement that they do not exist today.
Two adjacent things are worth knowing so you do not go looking for more. The Antigravity CLI has a headless mode, so you can drive it over SSH the way you can drive any CLI, but that is plumbing you build and maintain yourself. And Google's phone-reachable coding agent today is Jules, which clones your repository into a Google cloud VM and works there: real, useful, and a different category, because it runs on a copy in their cloud rather than steering the session on your desk.
The gap this page fills is local agent control. Antigravity's own agent runs where the editor runs, and there is no first-party way to answer its questions, approve its edits, or send it new work from a phone. The fix comes in from the side: a second agent, running in the same editor, with a remote surface of its own.
Set It Up in Three Steps
Install the extension from Open VSX. Open the Extensions view in Antigravity and search for Grok Build, or open the listing directly. You need Antigravity 2.1.1 or newer. On 2.0.x the install fails with a compatibility error, which the FAQ below explains and fixes. The extension walks you through installing the
grokCLI and signing in, one click per step.Link this device. In the extension, open the gear menu, choose Remote Control, then Sign in (link this device). The approval page opens in your browser. If the code is showing on a machine you are not sitting at, open /link and type it in by hand.
Open it on your phone. Visit afkpilot.com on the phone, sign in, and tap Install app to keep it one tap away.
That is the whole setup. There is no tunnel to keep alive, no port to forward, and no VPN to join.
What You Can Do From the Phone
It is the same session, not a separate agent and not a chatbot discussing your code from a distance. The workspace, the repository, and the conversation history are the ones open in Antigravity on your desk.
Send new work, not just read output
Watch tool calls and file exploration stream live
Approve permission prompts and answer the agent's questions
Browse the project's files and open, edit and save a text file
See every project and its recent conversations side by side, and start one in any of them without switching first
Switch the model and the reasoning effort
Fork a conversation to try a different direction without losing the original
The file panel is a real editor, not a viewer. Several files open as tabs, and on a wide screen they sit beside the chat. Text files up to 2 MiB open, images preview only, and there is no create, delete, or rename. If the agent changed a file underneath you while you were typing, you get a choice between reloading and overwriting rather than a silent clobber.
Images work in both directions. Videos never leave your machine.
What This Is Not
Not remote control of Antigravity's own agent. This steers the Grok Build agent running inside Antigravity. Antigravity's built-in agent stays local and unreachable from the phone.
Not a mobile IDE. You are steering an agent and making small edits, not doing a refactor by hand on a 6-inch screen.
Not a Google product. Antigravity is Google's. The extension and AFK Pilot are mine, and neither is affiliated with or endorsed by Google or SpaceXAI.
Not a substitute for your machine staying on. The agent runs on your hardware. The extension holds off idle sleep while a device is linked, so a turn you started from the phone is not cut short by the screensaver, and it releases that hold the moment you sign out. A closed lid still suspends on every operating system.
Privacy and What Leaves Your Machine
Messages are relayed in memory and never stored on our servers. Every linked device binds to your account and stays revocable at any time, so a lost phone is a revocation rather than an incident.
This is a relay, so your prompts and the agent's replies do pass through it in transit. Your files stay on your machine, where the agent reads them locally. If a third-party relay is outside your threat model, the self-hosted Tailscale projects listed on the general remote control page keep every byte on hardware you control, at the cost of a network setup you have to maintain. I would rather tell you that here than have you discover the architecture later.
Pricing
The free tier is one linked device and 100 remote messages a week, with the full chat interface. Remote Max is $5 a month and removes both limits. A fair-use burst cap of 20 messages a minute applies on every plan, and messages inside the editor itself are never limited.
The extension is free to install. The agent underneath is free to try with usage limits on any X or Grok account, and sustained use runs on SuperGrok, X Premium+, or an xAI API key. Antigravity itself is free to use on a personal Google account, with paid Google AI plans changing which models its own agent gets. None of that is affected by this setup.
FAQ
Can I use Antigravity from my phone?
You can steer a coding agent running inside Antigravity from your phone, but not the Antigravity editor itself. Install the Grok Build for VS Code (Community) extension from Open VSX, link the device with a one-time code, and open afkpilot.com on the phone. The agent runs on your machine, in your real workspace, and you drive it from the browser.
Does Antigravity have a mobile app?
No. Google does not ship an Antigravity phone app, and Antigravity has no first-party remote control for a session running on your own machine; the 2.0 announcement lists both remote control and cloud-deployed agents as still to come. If you want a Google coding agent you can reach from a phone browser today, that is Jules, and it works on a clone of your repo in a Google cloud VM rather than on your machine.
I get "Extension is not compatible with Code 2.0.6. Extension requires: ^1.90.0". How do I fix it?
Update Antigravity to 2.1.1 or newer, then install the extension normally. Antigravity 2.0.x reported its own product version, 2.0.x, to the extension host instead of the VS Code base version it is built on, so every extension declaring a ^1.x engine range was rejected. That was not specific to this extension. Google fixed it in 2.1.1, which reports base 1.107.0 again, comfortably above the extension's 1.106 floor.
Can I edit files remotely?
Yes. You can browse the project tree and open, edit and save a text file from the phone, with several files open as tabs at once. Images are preview only, text files cap at 2 MiB, and creating, deleting, and renaming are not available from the remote surface.
Does this control Gemini in Antigravity?
No. It controls the Grok Build agent running inside Antigravity, not Antigravity's own built-in agent, which runs Gemini by default with Claude and open models selectable. If what you want is your Antigravity agent answering you on the train, this does not do that, and nothing does today. Google has said remote control is coming.
Is it free?
There is a free tier: one linked device and 100 remote messages a week, and Remote Max is $5 a month for unlimited devices and messages. The extension itself is free to install, and the Grok Build agent is free to try with usage limits on any X or Grok account.
Does it work on iPhone and Android?
Yes. It runs in any modern mobile browser and installs as an app on both.
Do I need a tunnel or a VPN?
No. You pair once with a one-time code, and the extension dials out to the service, so there is nothing to forward and nothing to keep running. No tunnels, no config.
Is my code sent to a server?
Your prompts and the agent's replies are relayed in memory and never stored on our servers. Your files stay on your machine, where the agent reads them locally. Videos never leave your machine.
Does the same setup work in VS Code or Cursor?
Yes. The extension supports VS Code 1.106+, Cursor 3.x, and Antigravity 2.1.1+, and the remote layer connects through the extension, so whatever the extension runs in, this runs in. Cursor has its own wrinkle worth reading first: Cursor Remote Control. The plain VS Code version: Grok Remote Control.

AFK Pilot exists because a user asked for it, which is most of what I have to say about product work. I write that up here: what building in the open teaches me, not the tool tour.
