What it does

Antigravity Quota Watcher is a VS Code extension that polls your Antigravity IDE’s remaining API quota and renders it live in the status bar. It auto-detects the local service port, syncs login state, and can fall back to Google API mode for remote SSH or VS Code forks like Windsurf and Kiro.

The interesting bit

The “weekly limit detection” feature fires a real “Hi” test request at model pools (Gemini 3.x, Claude/GPT, Gemini 2.5) and parses HTTP 429 error details to distinguish between quota exhaustion, rate limiting, and server overload — then estimates reset time. It’s a clever hack, though the README warns this burns a small amount of quota to run.

Key highlights

• Three status-bar visual modes: progress bars, percentages, or dot matrices with color-coded thresholds (green/yellow/red/black)
• Dashboard panel with quota tables, connection status, account info, and one-click refresh/re-detect/logout
• Auto-inherits Antigravity’s proxy settings; can also read HTTPS_PROXY or use a manual override
• Supports both local token extraction and Google API authentication paths
• 8-second startup delay to avoid hammering the API on launch

Caveats

• The README openly admits the plugin is unofficial and “depends on Antigravity language server’s internal implementation details, which may change at any time”
• A current warning notes quota display may stick at 100% due to suspected official API changes; the “temporary fix” of US proxy nodes is itself marked as possibly失效 (no longer working), with quota now apparently decrementing in 20% chunks
• Windows ARM64 is explicitly unsupported; Linux requires lsof, netstat, or ss

Verdict

Grab this if you’re a heavy Antigravity user who keeps hitting invisible walls mid-session and wants telemetry in your peripheral vision. Skip it if you don’t use Antigravity, or if you find status-bar clutter more annoying than surprise quota death.
