Antigravity Tools is an open-source desktop app and headless proxy built with Tauri, Rust, and React. It manages multiple upstream web session accounts (like Google and Anthropic) and exposes standardized, local OpenAI, Anthropic, and Gemini API endpoints on port 8045. It includes automatic account rotation, quota tracking, smart self-healing on rate limits, and custom model routing.

How it works

Setup steps shown:

  1. Install via Homebrew: `brew tap lbjlaq/antigravity-manager https://github.com/lbjlaq/Antigravity-Manager && brew install --cask antigravity-tools` (or download DMG from GitHub releases).
  2. Launch Antigravity Manager and authenticate your Google account via OAuth.
  3. In the Service Configuration tab, click 'Start Service' to start the local proxy on port 8045.
  4. Copy the generated API key and send requests to `http://127.0.0.1:8045/v1/chat/completions` using OpenAI format.

What it's for

  • Run external developer tools like Claude Code CLI or JeikCode using existing web accounts
  • Switch between multiple accounts automatically when hitting 429 rate limits
  • Expose local OpenAI-compatible endpoints to test scripts and third-party desktop chat apps

Features

  • Multi-protocol API proxy supporting OpenAI, Anthropic, and Gemini formats on port 8045
  • Real-time quota monitoring and smart account recommendation dashboard
  • OAuth 2.0 authorization and JSON batch account import
  • Automatic silent rotation and retry on 429 or 401 response errors
  • Model router with regex mapping, tiered routing, and silent background downgrades
  • Imagen 3 image generation support via standard image APIs and chat parameters
  • Docker headless deployment option with web UI management

Why it was saved

  • @lapchik_tsarapchik, 7 February 2026: Lets you bypass quota limits and exposes a local OpenAI/Anthropic/Gemini-compatible API endpoint (port 8045) to use models like Claude 3.5/4.5 Sonnet and Gemini 2.0 Flash in external apps.
