🌟 Detailed Feature Matrix

1. 🎛️ Smart Account Dashboard

Global Real-time Monitoring: Instant insight into the health of all accounts, including average remaining quotas for Gemini Pro, Gemini Flash, Claude, and Gemini Image generation.
Smart Recommendation: The system uses a real-time algorithm to filter and recommend the "Best Account" based on quota redundancy, supporting one-click switching.
Active Account Snapshot: Visually displays the specific quota percentage and the last synchronization time of the currently active account.

2. 🔐 Powerful Account Management

OAuth 2.0 Authorization (Auto/Manual): Pre-generates a copyable authorization URL so you can finish auth in any browser; after the callback, the app auto-completes and saves the account (use “I already authorized, continue” if needed).
Multi-dimensional Import: Supports single token entry, JSON batch import, and automatic hot migration from V1 legacy databases.
Gateway-level Views: Supports switching between "List" and "Grid" views. Provides 403 Forbidden detection, automatically marking and skipping accounts with permission anomalies.

3. 🔌 Protocol Conversion & Relay (API Proxy)

Multi-Protocol Adaptation (Multi-Sink):
- OpenAI Format: Provides /v1/chat/completions endpoint, compatible with 99% of existing AI apps.
- Anthropic Format: Provides native /v1/messages interface, supporting all features of Claude Code CLI (e.g., chain-of-thought, system prompts).
- Gemini Format: Supports direct calls from official Google AI SDKs.
Smart Self-healing: When a request encounters 429 (Too Many Requests) or 401 (Expired), the backend triggers millisecond-level automatic retry and silent rotation, ensuring business continuity.

4. 🔀 Model Router Center

Series-based Mapping: Classify complex original model IDs into "Series Groups" (e.g., routing all GPT-4 requests uniformly to gemini-3-pro-high).
Expert Redirection: Supports custom regex-level model mapping for precise control over every request's landing model.
Tiered Routing [New]: Automatically prioritizes models based on account tiers (Ultra/Pro/Free) and reset frequencies to ensure stability for high-volume users.
Silent Background Downgrading [New]: Intelligently identifies background tasks (e.g., Claude CLI title generation) and reroutes them to Flash models to preserve premium quota.

5. 🎨 Multimodal & Imagen 3 Support

Advanced Image Control: Supports precise control over image generation tasks via OpenAI size (e.g., 1024x1024, 16:9) parameters or model name suffixes.
Enhanced Payload Support: The backend supports payloads up to 100MB (configurable), more than enough for 4K HD image recognition and processing.

curl -sSL https://raw.githubusercontent.com/lbjlaq/Antigravity-Manager/main/deploy/arch/install.sh | bash

Option 2: via Homebrew (If you have Linuxbrew installed)

brew tap lbjlaq/antigravity-manager https://github.com/lbjlaq/Antigravity-Manager
brew install --cask antigravity-tools

Other Linux Distributions

The AppImage will be automatically symlinked to your binary path with executable permissions.

Option B: Manual Download

Download from GitHub Releases:

macOS: .dmg (Universal, Apple Silicon & Intel)
Windows: .msi or portable .zip
Linux: .deb or AppImage

Option C: Docker Deployment (Recommended for NAS/Servers)

If you prefer running in a containerized environment, we provide a native Docker image. This image supports the v4.0.3 Native Headless architecture, automatically hosts frontend static resources, and allows for direct browser-based management.

Option 1: Direct Run (Recommended)

API_KEY: Required. Used for AI request authentication.
WEB_PASSWORD: Optional. Used for Web UI login. Defaults to API_KEY if NOT set.

docker run -d --name antigravity-manager \
  -p 8045:8045 \
  -e API_KEY=sk-your-api-key \
  -e WEB_PASSWORD=your-login-password \
  -e ABV_MAX_BODY_SIZE=104857600 \
  -v ~/.antigravity_tools:/root/.antigravity_tools \
  lbjlaq/antigravity-manager:latest

# Forgot keys? Run `docker logs antigravity-manager` or `grep -E '"api_key"|"admin_password"' ~/.antigravity_tools/gui_config.json`

[!TIP] 🧪 Pulling Beta / Preview Images: To test the latest Beta pre-release features, specify the corresponding Beta version tag (pre-releases are published independently and will never overwrite the latest stable tag):
# Pull a specific Beta pre-release version (check Docker Hub for all tags)
docker pull lbjlaq/antigravity-manager:v4.8.2-beta.0

# Run Beta container
docker run -d --name antigravity-manager-beta \
  -p 8045:8045 \
  -e API_KEY=sk-your-api-key \
  -e WEB_PASSWORD=your-login-password \
  -e ABV_MAX_BODY_SIZE=104857600 \
  -v ~/.antigravity_tools:/root/.antigravity_tools \
  lbjlaq/antigravity-manager:v4.8.2-beta.0
View all published Beta tags on Docker Hub Tags. If you wish to run the unreleased bleeding-edge beta branch directly, build locally: docker build -t lbjlaq/antigravity-manager:beta -f docker/Dockerfile ..

🔐 Authentication Scenarios

Scenario A: Only API_KEY is set
- Web Login: Use API_KEY to access the dashboard.
- API Calls: Use API_KEY for AI request authentication.
Scenario B: Both API_KEY and WEB_PASSWORD are set (Recommended)
- Web Login: Must use WEB_PASSWORD. Using API Key will be rejected (more secure).
- API Calls: Continue to use API_KEY. This allows you to share the API Key with team members while keeping the password for administrative access only.

🆙 Upgrade Guide for Older Versions

If you are upgrading from v4.0.1 or earlier, your installation won't have a WEB_PASSWORD set by default. You can add one using any of these methods:

Web UI (Recommended): Log in using your existing API_KEY, go to the API Proxy Settings page, find the Web UI Management Password section below the API Key, set your new password, and save.
Environment Variable (Docker): Stop the old container and start the new one with the added parameter -e WEB_PASSWORD=your_new_password. Note: Environment variables have the highest priority and will override any changes in the UI.
Config File (Persistent): Directly edit ~/.antigravity_tools/gui_config.json and add/modify "admin_password": "your_new_password" inside the proxy object.
- Note: WEB_PASSWORD is the environment variable name, while admin_password is the JSON key in the config file.

[!TIP] Priority Logic:

Environment Variable (WEB_PASSWORD) has the highest priority. If set, the application will always use it and ignore values in the configuration file.

Configuration File (gui_config.json) is used for persistent storage. When you change the password via Web UI and save, it is written here.

Fallback: If neither is set, it falls back to API_KEY; if even API_KEY is missing, a random one is generated.

Option 2: Use Docker Compose

Enter the docker directory and start the service:

cd docker
docker compose up -d

Log rotation: Compose limits JSON logs to 100m per file and keeps 3 files by default to prevent unbounded growth. Access URL: http://localhost:8045 (Admin Console) | http://localhost:8045/v1 (API Base) System Requirements:

RAM: 1GB recommended (minimum 256MB).

Persistence: Mount /root/.antigravity_tools to persist your data.

Architecture: Supports x86_64 and ARM64. See: Docker Deployment Guide (docker)

🛠️ Troubleshooting - Click to expand

macOS says "App is damaged"?

Due to macOS security gatekeeper, non-App Store apps might show this. You can fix it with:

Terminal Command (Recommended):

sudo xattr -rd com.apple.quarantine "/Applications/Antigravity Tools.app"

Homebrew Installation Advantage: When installing via Homebrew (brew install --cask antigravity-tools), quarantine attributes are automatically cleared upon installation for an out-of-the-box experience.

Linux window is black or empty?

On niri, Hyprland, Sway, and similar compositors, older builds forced GDK_BACKEND=x11 whenever DISPLAY was set, and WebKit then drew a black window. Update to a build that includes this fix, or launch once with:

env WEBKIT_DISABLE_DMABUF_RENDERER=1 ANTIGRAVITY_FORCE_WAYLAND=1 antigravity-tools

ANTIGRAVITY_FORCE_WAYLAND=1: keep native Wayland (do not force X11)
ANTIGRAVITY_FORCE_X11=1: force X11 if you still need it
WEBKIT_DISABLE_DMABUF_RENDERER=1: disable the WebKit DMA-BUF renderer

🔌 Quick Integration Examples

🔐 OAuth Authorization Flow (Add Account)

Go to Accounts → Add Account → OAuth.
The dialog pre-generates an authorization URL before you click any button. Click the URL to copy it to the system clipboard, then open it in the browser you prefer and complete authorization.
After consent, the browser opens a local callback page and shows “✅ Authorized successfully!”.
The app automatically continues the flow and saves the account; if it doesn’t, click “I already authorized, continue” to finish manually.

Note: the auth URL contains a one-time local callback port. Always use the latest URL shown in the dialog. If the app isn’t running or the dialog is closed during auth, the browser may show localhost refused connection.

Click Clear Config to remove Manager configuration and clean up legacy entries; click Restore to revert from backup.
On Windows, the path is C:\Users\\.config\opencode\ (same ~/.config/opencode rule).

Quick verification commands:

# Test antigravity-manager provider (supports --variant)
opencode run "test" --model antigravity-manager/claude-sonnet-4-5-thinking --variant high

# If opencode-antigravity-auth is installed, verify google provider still works independently
opencode run "test" --model google/antigravity-claude-sonnet-4-5-thinking --variant max

How to use in Python?

import openai

client = openai.OpenAI(
    api_key="sk-antigravity",
    base_url="http://127.0.0.1:8045/v1"
)

response = client.chat.completions.create(
    model="gemini-3-flash",
    messages=[{"role": "user", "content": "Hello, please introduce yourself"}]
)
print(response.choices[0].message.content)

How to use with Kilo Code?

Protocol Selection: We recommend using the Gemini protocol.
Base URL: Set it to http://127.0.0.1:8045.
Note:
- OpenAI Protocol Limitation: When using OpenAI mode, Kilo Code's request path will append /v1/chat/completions/responses, a non-standard path that will return 404 from Antigravity. Make sure to enter the Base URL and select Gemini mode.
- Model Mapping: Model names in Kilo Code may differ from Antigravity's defaults. If you encounter connection issues, set up custom mappings on the "Model Mapping" page and check the log files for debugging.

How to use Image Generation (Imagen 3)?

Method 1: OpenAI Images API (Recommended)

import openai

client = openai.OpenAI(
    api_key="sk-antigravity",
    base_url="http://127.0.0.1:8045/v1"
)

# Generate image
response = client.images.generate(
    model="gemini-3-pro-image",
    prompt="A futuristic cyberpunk city with neon lights",
    size="1920x1080",      # Supports any WIDTHxHEIGHT format, auto-calculates aspect ratio
    quality="hd",          # "standard" | "hd" | "medium"
    n=1,
    response_format="b64_json"
)

# Save image
import base64
image_data = base64.b64decode(response.data[0].b64_json)
with open("output.png", "wb") as f:
    f.write(image_data)

Supported parameters：

size: Any WIDTHxHEIGHT format (e.g. 1280x720, 1024x1024, 1920x1080), auto-calculates and maps to standard aspect ratios (21:9, 16:9, 9:16, 4:3, 3:4, 1:1)
quality:
- "hd" → 4K resolution (high quality)
- "medium" → 2K resolution (medium quality)
- "standard" → Default resolution (standard quality)
n: Number of images to generate (1-10)
response_format: "b64_json" or "url" (Data URI)

🎨 Expand to view more image generation methods & parameter mapping rules (Chat API / Model Suffix / Cherry Studio)

Method 2: Chat API + Parameters (✨ New)

All protocols (OpenAI, Claude) Chat APIs now support direct size and quality parameters:

# OpenAI Chat API
response = client.chat.completions.create(
    model="gemini-3-pro-image",
    size="1920x1080",      # ✅ Supports any WIDTHxHEIGHT format
    quality="hd",          # ✅ "standard" | "hd" | "medium"
    messages=[{"role": "user", "content": "A futuristic city"}]
)

# Claude Messages API
curl -X POST http://127.0.0.1:8045/v1/messages \
  -H "Content-Type: application/json" \
  -H "x-api-key: sk-antigravity" \
  -d '{
    "model": "gemini-3-pro-image",
    "size": "1280x720",
    "quality": "hd",
    "messages": [{"role": "user", "content": "A cute cat"}]
  }'

Parameter priority: imageSize parameter > quality parameter > model suffix

✨ New imageSize parameter support:

In addition to the quality parameter, you can now also use Gemini's native imageSize parameter:

# Using imageSize parameter (highest priority)
response = client.chat.completions.create(
    model="gemini-3-pro-image",
    size="16:9",           # Aspect ratio
    imageSize="4K",        # ✨ Direct resolution: "1K" | "2K" | "4K"
    messages=[{"role": "user", "content": "A futuristic city"}]
)

# Claude Messages API also supports imageSize
curl -X POST http://127.0.0.1:8045/v1/messages \
  -H "Content-Type: application/json" \
  -H "x-api-key: sk-antigravity" \
  -d '{
    "model": "gemini-3-pro-image",
    "size": "1280x720",
    "imageSize": "4K",
    "messages": [{"role": "user", "content": "A cute cat"}]
  }'

Parameter descriptions:

imageSize: Direct resolution specification ("1K" / "2K" / "4K")
quality: Infers resolution from quality level ("standard" → 1K, "medium" → 2K, "hd" → 4K)
Priority: If both imageSize and quality are specified, the system prioritizes imageSize

Method 3: Chat API + Model Suffix

response = client.chat.completions.create(
    model="gemini-3-pro-image-16-9-4k",  # Format: gemini-3-pro-image-[ratio]-[quality]
    messages=[{"role": "user", "content": "A futuristic city"}]
)

Model suffix explanation：

Aspect ratio: -16-9, -9-16, -4-3, -3-4, -21-9, -1-1
Quality: -4k (4K), -2k (2K), no suffix (standard)
Example: gemini-3-pro-image-16-9-4k → 16:9 ratio + 4K resolution

Method 4: Cherry Studio & Other Client Settings

In clients that support OpenAI protocol (e.g., Cherry Studio), you can configure image generation parameters via the Model Settings page:

Enter Model Settings: Select the gemini-3-pro-image model
Configure Parameters:
- Size: Enter any WIDTHxHEIGHT format (e.g. 1920x1080, 1024x1024)
- Quality: Choose standard / hd / medium
- Number: Set the number of images (1-10)
Send Request: Simply type your image description in the chat dialog

Parameter mapping rules:

size: "1920x1080" → Auto-calculated as 16:9 aspect ratio
quality: "hd" → Mapped to 4K resolution
quality: "medium" → Mapped to 2K resolution
