what is antigravity-route fr?

Antigravity Route is a small background program, written in the Rust programming language, that sits between your computer and Google's Antigravity (Code Assist) service. It takes your existing Antigravity subscription and makes it speak in the same format as Google's standard Gemini API, so tools built to talk to Gemini can use it instead. The README is upfront about risk: this project works by reverse engineering Google's internal APIs, and using it outside the official IDE extensions likely breaks Google's terms of service. Google can detect unusual usage patterns and may suspend or permanently close your account without warning. The authors take no responsibility for bans or lost data, so anyone trying this should understand they are accepting that risk themselves. Once running, the program acts as a daemon, meaning it runs quietly in the background and keeps your login information saved in a folder you choose. It supports live streaming of responses as they are generated, so replies appear word by word instead of all at once. It also includes a command line screen that shows colored progress bars for how much of your usage limits, both the five hour and weekly caps, you have used so far across the different model types. You can install it either through the Nix package manager or by building it yourself with Rust's Cargo tool. Setup involves three steps: starting the daemon with a storage folder, logging in through a Google OAuth link in your browser, and then checking your quota from the command line. Once authenticated, you point any Gemini-compatible tool, such as Opencode, Continue.dev, or Cursor, at the local server address, and it can use models like Claude or Gemini through your existing subscription. No separate API key is needed, since login is handled through OAuth.
