Antigravity Pulse

A lightweight, privacy-first quota monitor for Antigravity AI models.
See your remaining Gemini & Claude limits — directly in your status bar, without leaving your code.

Why I Built This

I was frustrated. In 2026, the VS Code / Antigravity marketplace is full of extensions that promise to show you your AI quota — but many of them are:

Scrapers quietly stealing your CSRF tokens to use your Claude 4 / Gemini 3 Pro credits on someone else's server.
Bloated extensions that open OAuth popups, store tokens, and make external API calls just to display a number.
Broken — because they hard-code a process name that Antigravity keeps changing between updates.

As a Computer Engineering student, I built Antigravity Pulse the right way:

Zero external calls. It queries the Antigravity language server running locally on your own machine. Your credentials never leave your computer.
Zero login required. It reads the CSRF token the IDE already has in memory — no OAuth, no browser popups.
Zero bloat. The extension is a single file. It uses no bundler, no framework, and runs once every 2 minutes.

Features

Feature	Description
🚀 Status Bar Tab	Shows `AGP` in your status bar like a native IDE tab. Click to open the dashboard.
🧲 Model Pinning	Click any model in the dashboard to pin its live percentage to the status bar. Click again to unpin.
📊 Hover Tooltip	Hover over the status bar for a full 2-column table: model name, remaining %, and countdown to reset.
🗂️ Dashboard	Opens a searchable Quick Pick panel with exact reset timestamps for all 6 models.
🔄 Auto Refresh	Polls every 2 minutes automatically.
🔴 Graceful Offline	If Antigravity is not running, it shows `AGP Offline` silently — no error popups.
🔒 Privacy-First	All data comes from your local `language_server_windows_x64.exe`. Nothing is sent anywhere.

How It Works

Antigravity runs a local HTTPS language server (language_server_windows_x64.exe) in the background. This server exposes a private gRPC-JSON endpoint that contains your account info and quota data.

Antigravity Pulse:

Finds the language server process using Get-CimInstance Win32_Process (Windows) or ps (macOS/Linux).
Extracts the dynamic CSRF token from its command-line arguments.
Discovers its listening HTTPS port using Get-NetTCPConnection.
Requests POST /exa.language_server_pb.LanguageServerService/GetUserStatus with the CSRF token.
Parses the quota fractions and reset times from userStatus.cascadeModelConfigData.clientModelConfigs.

The connection uses rejectUnauthorized: false because the local server generates a self-signed TLS certificate dynamically — this is intentional and safe since the connection never leaves 127.0.0.1.

Supported Models

Gemini 3.1 Pro (High)
Gemini 3.1 Pro (Low)
Gemini 3 Flash
Claude Sonnet 4.6 (Thinking)
Claude Opus 4.6 (Thinking)
GPT-OSS 120B (Medium)

Installation

From the Marketplace

Search Antigravity Pulse in the Antigravity Extensions panel.
Click Install.
Your quota appears in the bottom-right status bar automatically.

From Source

git clone https://github.com/AyanMemon296/antigravity-pulse-extension.git
cd antigravity-pulse-extension
npm install
npm run compile

Then press F5 in Antigravity to launch the Extension Development Host.

Requirements

Antigravity IDE (Windows, macOS, or Linux)
The Antigravity language server must be running (it starts automatically with the IDE)
Node.js 18+ (for development only)

Extension Settings

This extension contributes the following settings:

antigravity-pulse.refreshInterval: Set the quota polling interval in milliseconds (default is 120000 or 2 minutes).
antigravity-pulse.showNotifications: Enable or disable error notifications when the language server is unreachable.

Troubleshooting & Known Issues

"AGP Offline" Status: This usually means the Antigravity Language Server hasn't finished booting up. Give it 10-15 seconds after opening the IDE.
VPN/Proxy: If you are using a strict system-wide proxy, ensure 127.0.0.1 is whitelisted, or the extension won't be able to "talk" to the IDE.

Security Notes

No outbound network requests. Every HTTP call targets 127.0.0.1 only.
No token storage. The CSRF token is read fresh from the process on every discovery cycle and is never written to disk.
No telemetry. The extension collects and sends zero data.
The rejectUnauthorized: false flag is required to connect to the IDE's dynamically-generated self-signed certificate. It does not weaken any real security because the connection is strictly loopback-only.
