# NoeFabris/opencode-antigravity-auth

Enable Opencode to authenticate against Antigravity (Google's IDE) via OAuth so you can use Antigravity rate limits and access models like gemini-3-pro and claude-opus-4-5-thinking with your Google credentials.

## What it is
An OpenCode plugin that authenticates against Google's Antigravity IDE via OAuth, letting users access Gemini and Claude models with their Google credentials and Antigravity/Gemini CLI rate limits. It supports multiple Google accounts with automatic rotation when rate-limited.

## Use cases
- use gemini 3 pro in opencode with my google account
- access claude opus via google antigravity oauth
- rotate multiple google accounts when rate limited in opencode
- use antigravity quota for coding agent models
- enable thinking models with configurable budgets in opencode
- add gemini web search grounding to opencode

## When to choose
- You use OpenCode and want Gemini or Claude models through your existing Google credentials
- You want to pool Antigravity and Gemini CLI quotas with automatic account rotation
- You need extended thinking models and search grounding inside OpenCode

## When to avoid
- You are unwilling to risk Google account bans - the plugin violates Google's Terms of Service
- You need an officially supported or Google-endorsed authentication path
- You don't use OpenCode as your coding agent
