Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Request Flow:

  1. Claude Code CLI sends request in Anthropic Messages API format
  2. CommonsProxy routes to appropriate provider based on account configuration
  3. Transforms request to provider-specific format (Google Generative AI, Anthropic, OpenAI, GitHub)
  4. Sends to provider's API using OAuth or API Key authentication
  5. Converts response back to Anthropic format with full streaming and thinking support

Key Features:

  • 🔄 Multi-Provider Support: Use Google, Anthropic, OpenAI, GitHub Models, GitHub Copilot, and OpenRouter accounts
  • 🔐 Flexible Authentication: OAuth 2.0 (Google), Device Auth (Copilot, Codex), or API Keys (others)
  • ⚖️ Intelligent Load Balancing: Hybrid/Sticky/Round-Robin strategies
  • 📊 Real-time Quota Tracking: Dashboard shows usage across all providers
  • 💾 Prompt Caching: Maintains cache continuity with sticky account selection
  • 🎨 Web Management UI: Easy account management and monitoring

3. Verify It's Working

# Health check
curl http://localhost:8080/health

# Check account status and quota limits
curl "http://localhost:8080/account-limits?format=table"

Using with Claude Code CLI

Configure Claude Code

You can configure these settings in two ways:

Via Web Console (Recommended)

  1. Open the WebUI at http://localhost:8080.
  2. Go to SettingsClaude CLI.
  3. Select your preferred models and click Apply to Claude CLI.

[!TIP] > Configuration Precedence: System environment variables (set in shell profile like .zshrc) take precedence over the settings.json file. If you use the Web Console to manage settings, ensure you haven't manually exported conflicting variables in your terminal.

Manual Configuration

Create or edit the Claude Code settings file:

macOS: ~/.claude/settings.json Linux: ~/.claude/settings.json Windows: %USERPROFILE%\.claude\settings.json

Add this configuration:

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "test",
    "ANTHROPIC_BASE_URL": "http://localhost:8080",
    "ANTHROPIC_MODEL": "claude-opus-4-5-thinking",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "claude-opus-4-5-thinking",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-4-5-thinking",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-sonnet-4-5",
    "CLAUDE_CODE_SUBAGENT_MODEL": "claude-sonnet-4-5-thinking",
    "ENABLE_EXPERIMENTAL_MCP_CLI": "true"
  }
}

Or to use Gemini models:

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "test",
    "ANTHROPIC_BASE_URL": "http://localhost:8080",
    "ANTHROPIC_MODEL": "gemini-3-pro-high[1m]",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "gemini-3-pro-high[1m]",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "gemini-3-flash[1m]",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "gemini-3-flash[1m]",
    "CLAUDE_CODE_SUBAGENT_MODEL": "gemini-3-flash[1m]",
    "ENABLE_EXPERIMENTAL_MCP_CLI": "true"
  }
}

Load Environment Variables

Add the proxy settings to your shell profile:

macOS / Linux:

echo 'export ANTHROPIC_BASE_URL="http://localhost:8080"' >> ~/.zshrc
echo 'export ANTHROPIC_AUTH_TOKEN="test"' >> ~/.zshrc
source ~/.zshrc

For Bash users, replace ~/.zshrc with ~/.bashrc

Windows (PowerShell):

Add-Content $PROFILE "`n`$env:ANTHROPIC_BASE_URL = 'http://localhost:8080'"
Add-Content $PROFILE "`$env:ANTHROPIC_AUTH_TOKEN = 'test'"
. $PROFILE

Windows (Command Prompt):

setx ANTHROPIC_BASE_URL "http://localhost:8080"
setx ANTHROPIC_AUTH_TOKEN "test"

Restart your terminal for changes to take effect.

Run Claude Code

# Make sure the proxy is running first
commons-proxy start

# In another terminal, run Claude Code
claude

Note: If Claude Code asks you to select a login method, add "hasCompletedOnboarding": true to ~/.claude.json (macOS/Linux) or %USERPROFILE%\.claude.json (Windows), then restart your terminal and try again.

Multiple Claude Code Instances (Optional)

To run both the official Claude Code and CommonsProxy version simultaneously, add this alias:

macOS / Linux:

# Add to ~/.zshrc or ~/.bashrc
alias claude-commons='CLAUDE_CONFIG_DIR=~/.claude-account-commons ANTHROPIC_BASE_URL="http://localhost:8080" ANTHROPIC_AUTH_TOKEN="test" command claude'

Windows (PowerShell):

# Add to $PROFILE
function claude-commons {
    $env:CLAUDE_CONFIG_DIR = "$env:USERPROFILE\.claude-account-commons"
    $env:ANTHROPIC_BASE_URL = "http://localhost:8080"
    $env:ANTHROPIC_AUTH_TOKEN = "test"
    claude
}

Then run claude for official API or claude-commons for this proxy.


Available Models

Claude Models

| Model ID | Description | | ---------------------------- | ---------------------------------------- | | claude-sonnet-4-5-thinking | Claude Sonnet 4.5 with extended thinking | | claude-opus-4-5-thinking | Claude Opus 4.5 with extended thinking | | claude-sonnet-4-5 | Claude Sonnet 4.5 without thinking |

Gemini Models

| Model ID | Description | | ------------------- | ------------------------------- | | gemini-3-flash | Gemini 3 Flash with thinking | | gemini-3-pro-low | Gemini 3 Pro Low with thinking | | gemini-3-pro-high | Gemini 3 Pro High with thinking |

Gemini models include full thinking support with thoughtSignature handling for multi-turn conversations.


Multi-Account Load Balancing

When you add multiple accounts, the proxy intelligently distributes requests across them using configurable selection strategies.

Account Selection Strategies

Choose a strategy based on your needs:

| Strategy | Best For | Description | | --- | --- | --- | | Hybrid (Default) | Most users | Smart selection combining health score, token bucket rate limiting, quota awareness, and LRU freshness | | Sticky | Prompt caching | Stays on the same account to maximize cache hits, switches only when rate-limited | | Round-Robin | Even distribution | Cycles through accounts sequentially for balanced load |

Configure via CLI:

commons-proxy start --strategy=hybrid    # Default: smart distribution
commons-proxy start --strategy=sticky    # Cache-optimized
commons-proxy start --strategy=round-robin  # Load-balanced

Or via WebUI: Settings → Server → Account Selection Strategy

Model Fallback

When all accounts are exhausted for a requested model, the proxy can automatically fall back to an alternate model:

commons-proxy start --fallback
# Or: FALLBACK=true commons-proxy start

Fallback mappings preserve thinking capability (thinking models fall back to other thinking models). Fallback is disabled on recursive calls to prevent infinite chains. Configure in the WebUI under Settings → Server.

How It Works

  • Health Score Tracking: Accounts earn points for successful requests and lose points for failures/rate-limits
  • Token Bucket Rate Limiting: Client-side throttling with regenerating tokens (50 max, 6/minute)
  • Quota Awareness: Accounts with critical quota (<5%) are deprioritized; exhausted accounts trigger emergency fallback
  • Emergency Fallback: When all accounts appear exhausted, bypasses checks with throttle delays (250-500ms)
  • Automatic Cooldown: Rate-limited accounts recover automatically after reset time expires
  • Invalid Account Detection: Accounts needing re-authentication are marked and skipped
  • Prompt Caching Support: Session IDs derived from conversation enable cache hits across turns

Monitoring

Check account status, subscription tiers, and quota anytime:

# Web UI: http://localhost:8080/ (Accounts tab - shows tier badges and quota progress)
# CLI Table:
curl "http://localhost:8080/account-limits?format=table"

CLI Management Reference

If you prefer using the terminal for management:

# List all accounts
commons-proxy accounts list

# Verify account health
commons-proxy accounts verify

# Interactive CLI menu
commons-proxy accounts

Web Management Console

The proxy includes a built-in, modern web interface for real-time monitoring and configuration. Access the console at: http://localhost:8080 (default port).

CommonsProxy Console

Key Features

  • Real-time Dashboard: Monitor request volume, active accounts, model health, and subscription tier distribution.
  • Visual Model Quota: Track per-model usage and next reset times with color-coded progress indicators.
  • Account Management: Add/remove Google accounts via OAuth, view subscription tiers (Free/Pro/Ultra) and quota status at a glance.
  • Manual OAuth Mode: Add accounts on headless servers by copying the OAuth URL and pasting the authorization code.
  • Claude CLI Configuration: Edit your ~/.claude/settings.json directly from the browser.
  • Persistent History: Tracks request volume by model family for 30 days, persisting across server restarts.
  • Time Range Filtering: Analyze usage trends over 1H, 6H, 24H, 7D, or All Time periods.
  • Smart Analysis: Auto-select top 5 most used models or toggle between Family/Model views.

  • Advanced Tuning: Configure retries, timeouts, and debug mode on the fly.
  • Multi-language Interface: Full support for English, Chinese (中文), Indonesian (Bahasa), and Portuguese (PT-BR).

Advanced Configuration

While most users can use the default settings, you can tune the proxy behavior via the Settings → Server tab in the WebUI or by creating a config.json file.

Configurable Options

  • API Key Authentication: Protect /v1/* API endpoints with API_KEY env var or apiKey in config.
  • WebUI Password: Secure your dashboard with WEBUI_PASSWORD env var or in config.
  • Custom Port: Change the default 8080 port.
  • Retry Logic: Configure maxRetries, retryBaseMs, and retryMaxMs.
  • Rate Limit Handling: Comprehensive rate limit detection from headers and error messages with intelligent retry-after parsing.
  • Load Balancing: Adjust defaultCooldownMs and maxWaitBeforeErrorMs.
  • Persistence: Enable persistTokenCache to save OAuth sessions across restarts.
  • Max Accounts: Set maxAccounts (1-100) to limit the number of Google accounts. Default: 10.
  • Endpoint Fallback: Automatic 403/404 endpoint fallback for API compatibility.

Refer to config.example.json for a complete list of fields and documentation.


macOS Menu Bar App

For macOS users who prefer a native experience, there's a companion menu bar app that provides quick access to server controls without touching the terminal. Get it from: commons-proxy-bar

Note: This is a GUI wrapper only. You still need to install and setup the proxy server first using one of the installation methods above.

AntiGravity Claude Proxy Bar

Key Features

  • Server Control: Start/stop the proxy server with a single click or ⌘S shortcut.
  • Status Indicator: Menu bar icon shows server running state at a glance.
  • WebUI Access: Open the web management console directly from the menu.
  • Port Configuration: Customize the proxy server port (default: 8080).
  • Auto-Start Options: Launch server on app start and launch app at login.
  • Native Experience: Clean, native SwiftUI interface designed for macOS.

API Endpoints

| Endpoint | Method | Description | | ----------------- | ------ | --------------------------------------------------------------------- | | /health | GET | Health check | | /account-limits | GET | Account status and quota limits (add ?format=table for ASCII table) | | /v1/messages | POST | Anthropic Messages API | | /v1/models | GET | List available models | | /refresh-token | POST | Force token refresh |


Testing

Run the test suite (requires server running):

# Start server in one terminal
npm start

# Run tests in another terminal
npm test

Individual tests:

npm run test:signatures    # Thinking signatures
npm run test:multiturn     # Multi-turn with tools
npm run test:streaming     # Streaming SSE events
npm run test:interleaved   # Interleaved thinking
npm run test:images        # Image processing
npm run test:caching       # Prompt caching
npm run test:strategies    # Account selection strategies
npm run test:cache-control # Cache control field stripping

Troubleshooting

Windows: OAuth Port Error (EACCES)

On Windows, the default OAuth callback port (51121) may be reserved by Hyper-V, WSL2, or Docker. If you see:

Error: listen EACCES: permission denied 0.0.0.0:51121

The proxy will automatically try fallback ports (51122-51126). If all ports fail, try these solutions:

Option 1: Use a Custom Port (Recommended)

Set a custom port outside the reserved range:

# Windows PowerShell
$env:OAUTH_CALLBACK_PORT = "3456"
commons-proxy start

# Windows CMD
set OAUTH_CALLBACK_PORT=3456
commons-proxy start

# Or add to your .env file
OAUTH_CALLBACK_PORT=3456

Option 2: Reset Windows NAT

Run as Administrator:

net stop winnat
net start winnat

Option 3: Check Reserved Ports

See which ports are reserved:

netsh interface ipv4 show excludedportrange protocol=tcp

If 51121 is in a reserved range, use Option 1 with a port outside those ranges.

Option 4: Permanently Exclude Port (Admin)

Reserve the port before Hyper-V claims it (run as Administrator):

netsh int ipv4 add excludedportrange protocol=tcp startport=51121 numberofports=1

Note: The server automatically tries fallback ports (51122-51126) if the primary port fails.


"Could not extract token from Cloud Code IDE"

If using single-account mode with Windsurf/Cursor:

  1. Make sure the IDE is installed and running
  2. Ensure you're logged in with your Google account

Or add accounts via OAuth instead: commons-proxy accounts add

401 Authentication Errors

The token might have expired. Try:

curl -X POST http://localhost:8080/refresh-token

Or re-authenticate the account:

commons-proxy accounts

Rate Limiting (429)

With multiple accounts, the proxy automatically switches to the next available account. With a single account, you'll need to wait for the rate limit to reset.

Account Shows as "Invalid"

Re-authenticate the account:

commons-proxy accounts
# Choose "Re-authenticate" for the invalid account

Security

  • WebUI Password: Set WEBUI_PASSWORD to protect the management dashboard. Password comparison uses crypto.timingSafeEqual() to prevent timing attacks.
  • API Key: Set API_KEY to protect /v1/* API endpoints from unauthorized access.
  • Bounded Caches: Internal signature caches are bounded (max 10,000 entries) with LRU eviction to prevent memory exhaustion.
  • Schema Depth Limits: JSON schema sanitization enforces a depth limit of 50 to prevent stack overflow from deeply nested or recursive schemas.
  • Config Redaction: Sensitive values (tokens, API keys, passwords) are redacted in WebUI API responses.

Development

For Developers & Contributors

This project uses a local Tailwind CSS build system. CSS is pre-compiled and included in the repository, so you can run the project immediately after cloning.

Quick Start

git clone https://github.com/AryanVBW/CommonsProxy.git
cd CommonsProxy
npm install  # Automatically builds CSS via prepare hook
npm start    # Start server (no rebuild needed)

Frontend Development

If you need to modify styles in public/css/src/input.css:

# Option 1: Build once
npm run build:css

# Option 2: Watch for changes (auto-rebuild)
npm run watch:css

# Option 3: Watch both CSS and server (recommended)
npm run dev:full

File Structure:

  • public/css/src/input.css - Source CSS with Tailwind @apply directives (edit this)
  • public/css/style.css - Compiled & minified CSS (auto-generated, don't edit)
  • tailwind.config.js - Tailwind configuration
  • postcss.config.js - PostCSS configuration

Backend-Only Development

If you're only working on backend code and don't need frontend dev tools:

npm install --production  # Skip devDependencies (saves ~20MB)
npm start

Note: Pre-compiled CSS is committed to the repository, so you don't need to rebuild unless modifying styles.
