what is antigravity-manager fr?

Antigravity Manager is a desktop application for managing multiple AI service accounts and acting as a local API proxy. It is built with Tauri (a framework that combines a Rust backend with a React frontend to produce lightweight desktop apps) and runs on Windows, macOS, and Linux. The core problem it solves is account juggling. If you use multiple Google or Anthropic accounts to access AI models, switching between them manually is tedious. Antigravity Manager stores those accounts, monitors their quota levels in real time, and can switch to the account with the most remaining quota automatically, so your requests keep flowing even when one account hits its limit. The proxy side of the tool exposes a local API server that accepts requests formatted for OpenAI's interface, Anthropic's interface, or Google's interface, then translates and forwards them to the actual upstream service using whichever account has capacity. This means tools or applications built against one provider's format can be pointed at Antigravity Manager without code changes. When a request fails because an account is rate-limited or its token has expired, the proxy silently retries using another account. Additional features include a model routing layer that lets you map one model name to another (for example, redirect all GPT-4 requests to a different model), support for image generation, and Docker deployment for running the proxy on a server or NAS device. The application's interface and documentation are primarily in Chinese.
