Antigravity Manager

​
Welcome to Antigravity Manager

Antigravity Manager is a professional AI account management and protocol proxy system built with Tauri v2, Rust, and React. It transforms your Google and Anthropic web sessions into standardized API interfaces, providing a stable, high-speed, and cost-effective local AI relay station. Version Tauri Rust React

​
Why Antigravity Manager?

Antigravity Manager eliminates the protocol gap between different AI providers, allowing you to:
  • Unify Access: Use a single API endpoint for multiple AI services
  • Smart Routing: Automatically select the best available account based on quota
  • Multi-Protocol Support: OpenAI, Anthropic, and Gemini formats all in one
  • Privacy First: All processing happens locally on your machine

​
Key Features

Smart Account Dashboard

Real-time monitoring of all account health, average remaining quotas, and intelligent best-account recommendations with one-click switching.

Professional Account Management

OAuth 2.0 authorization (auto/manual), multi-dimensional import (Token, JSON, V1 migration), and 403 forbidden detection with automatic skipping.

Protocol Conversion & Relay

OpenAI /v1/chat/completions, Anthropic /v1/messages, and native Gemini formats with smart self-healing on 429/401 errors.

Model Router Center

Series-based mapping, expert-level redirection with regex, tiered routing by account type, and silent background downgrading.

Multimodal Support

Advanced image generation with Imagen 3, supports up to 100MB payloads (configurable), and precise aspect ratio control.
