CC-Router

Local multi-account router for Claude Max and OpenAI ChatGPT/Codex subscriptions.
Distribute Claude Code requests across Claude subscriptions, and expose an OpenAI Responses-compatible route for Codex CLI through the same proxy.

npm License: MIT

An actively maintained fork of VictorMinemu/CC-Router, published as @timo972/cc-router with bug fixes and added features — most notably cache-aware sticky session routing, which pins each Claude Code session to one account so a conversation keeps hitting the same prompt cache instead of scattering its shared prefix across accounts. Also includes load-aware account leases, byte-transparent streaming fixes, and a round of security hardening. See CHANGELOG.md for the full list.

CC-Router Dashboard

Features

  • Cache-aware session routing — keep each Claude Code session on one account while distributing new sessions across 2-20 Claude Max accounts
  • Multi-provider routing — route openai/* models to OpenAI ChatGPT/Codex subscription accounts and Claude models to Claude subscriptions
  • Transparent Claude proxy — Claude Code works normally; streaming, thinking, tool use, prompt caching all pass through
  • Codex CLI support — configure Codex to use CC-Router as a Responses-compatible provider
  • Automatic token refresh — OAuth tokens are refreshed before they expire, saved atomically to disk
  • Model-aware rate limits — avoids accounts whose requested-model or global allowance is exhausted, and respects scoped cooldowns
  • Client mode — connect another device you own to your private CC-Router (cc-router client connect <url>)
  • Claude Desktop support — route Cowork / Agent-mode traffic through CC-Router via mitmproxy interception (macOS, Windows, Linux)
  • Guided setup wizard — interactive cc-router setup extracts tokens from Keychain or credentials file, configures everything
  • Live dashboard — real-time terminal UI showing account health, request counts, token usage, recent activity
  • Proxy authentication — Bearer / x-api-key secret; required when binding a non-loopback interface
  • Update notifications — new releases are announced in the CLI; installing is opt-in (autoUpdate: true)
  • Multiple deployment modes — background daemon, native OS auto-start (launchd/systemd), foreground, Docker Compose
  • Cross-platform — macOS, Linux, Windows; Node.js 20+

All standard Claude Code features work transparently on the Claude route: streaming, extended thinking, tool use, prompt caching. OpenAI subscription routing is available for Codex-compatible Responses requests and Claude Code cross-routing with the limitations documented below.

Cache-aware Claude account routing

CC-Router keeps requests from one Claude Code session on the same eligible Anthropic subscription account. This session affinity remains account-based and preserves prompt-cache locality instead of scattering a conversation's shared prefix across account-specific caches. The model requested by each Messages call affects whether the bound account is still eligible; changing models does not create a second binding, but it can make the existing binding fail over when that account cannot serve the new model. New sessions prefer the account with the fewest in-flight requests, then the fewest bound sessions, then included allowance over paid extra usage, then the most applicable global and requested-model headroom; exact ties use a rotating round-robin order.

Anthropic cooldowns, effective global or requested-model quota exhaustion, disabled accounts, invalid authentication, and unhealthy accounts are hard exclusions. The configured per-account percentage caps are softer policy controls: when at least one account is otherwise usable but every usable account is over a configured cap, CC-Router may explicitly fall back to the least-loaded capped account. It never uses that fallback to bypass an Anthropic cooldown or exhausted effective quota.

If an upstream account returns 401, 429, or 529, CC-Router passes that response through unchanged and invalidates the session's affinity. The client's next retry can then select another usable account; the router never retries after response bytes have started. If no account is usable before forwarding begins, the router instead returns a local Anthropic-shaped 429 whenever any account is blocked by a rate limit or exhausted quota. That 429 includes Retry-After only when a trustworthy unblock time is known. A local 503 is reserved for entirely non-rate-limit unavailability, such as all accounts being disabled or unhealthy. Either local response makes no Anthropic Messages request. Affinity mappings exist only in process memory, expire after one hour of inactivity, and are capped in size. Session IDs are never persisted or logged.

Streaming remains byte-transparent. In particular, CC-Router never appends a synthetic message_stop event. proxyRequestTimeoutMs protects only the phase before Anthropic response headers arrive; once a response starts, its body continues through the native byte-exact proxy pipe. Automatic cc-router configure setup manages Claude Code's event-level and byte-level stream idle watchdogs at 30 minutes. Restart any existing Claude Code process after configuration so it inherits those values.

Claude Desktop support is opt-in and requires a small interceptor (mitmproxy) because Claude Desktop doesn't expose a custom API endpoint setting. See Claude Desktop support.


Use cases

Heavy user — one account isn't enough

Claude Max has rate limits per account. If you hit them regularly mid-session — waiting for cooldowns, getting 429s — you're a good candidate.

With two accounts you double your effective rate limit. With three, you triple it. The proxy distributes requests automatically; you don't change how you use Claude Code at all.

1 account  →  hit limit, wait 60s, continue
3 accounts →  new sessions spread across all three; each session stays cache-local

Quickstart

# 1. Install
npm install -g @timo972/cc-router

# 2. Wizard: extract tokens + configure Claude Code automatically
cc-router setup

# 3. Start the proxy
cc-router start

# 4. Use Claude Code normally — the proxy is transparent
claude

That's it. Claude Code will route through the proxy without any further changes.

On first run, cc-router start asks how you want to run (background/foreground, auto-start on boot, server mode) and remembers your choice. Next time, it just starts. To change preferences later:

cc-router start --reconfigure

Installation

Requirements: Node.js 20 or 22.

npm install -g @timo972/cc-router

Verify:

cc-router --version

Setup by platform

macOS

cc-router can extract OAuth tokens directly from the macOS Keychain — no manual copy-pasting needed.

cc-router setup
# Select "Extract automatically from macOS Keychain"

For multiple accounts, you need to switch accounts in Claude Code between extractions:

# Account 1 is already logged in — run setup and extract
cc-router setup

# To add account 2:
claude logout && claude login   # log in with account 2
cc-router setup --add           # extract and merge
claude logout && claude login   # log back in with account 1

Linux

Tokens are read from ~/.claude/.credentials.json:

cc-router setup
# Select "Read from ~/.claude/.credentials.json"

Make sure Claude Code is installed and you have run claude login at least once.

Windows

Same as Linux — tokens are read from ~/.claude/.credentials.json (Windows path: %USERPROFILE%\.claude\.credentials.json).

Claude Code → cc-router:3456 → api.anthropic.com

Best for personal use. No Docker required. Runs in the background by default, auto-starts on boot if you choose.

cc-router start

Full mode with LiteLLM (optional — requires Docker)

Claude Code → cc-router:3456 → LiteLLM:4000 → api.anthropic.com

Adds a LiteLLM layer for usage logging, rate limiting, and a web dashboard at http://localhost:4000/ui.

cc-router docker up
# or: cc-router start --litellm

See docs/litellm-setup.md for details.


Codex CLI support (experimental)

CC-Router exposes an OpenAI Responses-compatible endpoint for Codex CLI at /v1/responses. This lets Codex use OpenAI ChatGPT/Codex subscription accounts through the same local router that Claude Code uses for Claude subscriptions.

Configure Codex:

cc-router configure codex --model openai/gpt-5-codex

This writes a managed provider block to ~/.codex/config.toml:

model = "openai/gpt-5-codex"
model_provider = "cc-router"

[model_providers.cc-router]
name = "CC-Router"
base_url = "http://localhost:3456/v1"
wire_api = "responses"
env_key = "CC_ROUTER_TOKEN"

Configure router-side model defaults and aliases:

cc-router configure models \
  --claude-model claude-sonnet-4-6 \
  --openai-model gpt-5-codex

This writes modelRouting to ~/.cc-router/config.json. It sets the Claude default, the OpenAI default, and practical aliases so claude/sonnet, sonnet, openai/default, and openai/codex resolve to the models you selected. Restart the router after changing these values.

Model discovery is dynamic. GET /v1/models returns an OpenAI-compatible model list by querying the configured Anthropic and OpenAI subscription APIs live:

curl http://localhost:3456/v1/models

Results are provider-prefixed, for example anthropic/claude-sonnet-4-6 and openai/gpt-5-codex. Configured aliases such as openai/codex are added when their upstream model is available. If one provider is temporarily unavailable, CC-Router still returns the models discovered from the other providers.

Then run Codex with the proxy secret in CC_ROUTER_TOKEN when your router is password-protected:

CC_ROUTER_TOKEN=cc-rtr-your-secret codex -m openai/gpt-5.5

Model prefixes:

Prefix Upstream
openai/* OpenAI ChatGPT/Codex subscription route
claude/* Claude subscription route
anthropic/* Claude subscription route

Examples after the configuration above:

Public model Routed upstream model
openai/codex gpt-5-codex
openai/default gpt-5-codex
claude/sonnet claude-sonnet-4-6

Claude Code can also send a /v1/messages request with an openai/* model. CC-Router translates that Anthropic Messages request into an OpenAI Responses request and converts JSON or basic text SSE responses back into Anthropic-shaped message responses.

Current limitation: OpenAI-to-Anthropic streaming currently covers text deltas and final usage. Streaming tool-call normalization is still experimental.

OpenAI subscription account records are separated from Claude accounts with provider: "openai_subscription" so they do not enter the Anthropic token pool:

{
  "id": "openai-primary",
  "provider": "openai_subscription",
  "accessToken": "eyJ...",
  "refreshToken": "...",
  "expiresAt": 1999999999000,
  "scopes": ["openid", "profile", "email", "offline_access"]
}

Recommended OpenAI subscription login:

cc-router accounts login-openai

This uses the Codex device-code auth flow: the CLI prints a verification URL and one-time code, you approve the login in your browser, and CC-Router saves the resulting OpenAI subscription account record.

Manual account entry is also available for debugging:

cc-router accounts add-openai

This prompts for the OpenAI access token, refresh token, expiry timestamp, and scopes, validates the record shape, and saves it without overwriting Claude accounts.


Client mode — connecting your own devices

Client mode lets you connect another device you own to your private CC-Router over a trusted private network. It is not intended for sharing subscription accounts or proxy access with other people, or for exposing CC-Router to the public internet.

The setup wizard asks about this at the very first step:

cc-router setup
# → What do you want to do?
#   • Host CC-Router on this machine
#   • Connect to your existing CC-Router server  ← pick this

Or use the dedicated command directly:

# Connect another device you own over your private network
cc-router client connect http://192.168.1.50:3456 --secret cc-rtr-abc123...

# Check status
cc-router client status

# Disconnect (restores Claude Code defaults)
cc-router client disconnect

Client mode writes ANTHROPIC_BASE_URL and ANTHROPIC_AUTH_TOKEN into ~/.claude/settings.json, so Claude Code talks directly to the remote proxy. Nothing runs locally — no accounts, no proxy process, no resources.

CLI reference

cc-router client connect <url>       Connect Claude Code to a CC-Router server
cc-router client connect --desktop   Also configure Claude Desktop interception
cc-router client connect -s <secret> Pass the proxy secret inline (or use --secret)
cc-router client disconnect          Revert all client configuration
cc-router client status              Show current connection + remote server health
cc-router client start-desktop       Start the Claude Desktop mitmproxy interceptor
cc-router client stop-desktop        Stop the Claude Desktop interceptor

Claude Desktop support

Claude Desktop (chat + Cowork) can be routed through CC-Router, but unlike Claude Code it does not respect ANTHROPIC_BASE_URL. It talks directly to api.anthropic.com via an embedded Anthropic SDK. To redirect its traffic, CC-Router uses mitmproxy in local redirect mode — a process-scoped interceptor that only captures Claude Desktop's network traffic and forwards it to the proxy.

This is opt-in — the setup wizard will ask if you want it.

Requirements

  • mitmproxy ≥ 10.1.5 (macOS, Windows) or ≥ 11.1 (Linux — requires kernel ≥ 6.8)
  • Admin access to install the mitmproxy CA certificate
  • On macOS: manual approval of mitmproxy's Network Extension (one time, via System Settings)

Installing mitmproxy

# macOS
brew install mitmproxy

# Windows
# Download the installer from https://mitmproxy.org/downloads/
# (or: pip install mitmproxy)

# Linux
pip install mitmproxy        # kernel 6.8+ required for local mode

Enabling Desktop interception

During cc-router setup or cc-router client connect, answer Yes when asked about Claude Desktop. The wizard will:

  1. Check that mitmproxy is installed
  2. Generate the mitmproxy CA certificate (if not already present)
  3. Install the CA into the OS trust store (requires sudo/admin)
  4. Write the redirect addon to ~/.cc-router/interceptor/addon.py
  5. On macOS, prompt you to approve the Network Extension

Then start the interceptor:

cc-router client start-desktop

Open Claude Desktop and send a message. The request will be intercepted and redirected to CC-Router. Requests carrying exactly one valid X-Claude-Code-Session-Id receive cache-aware sticky affinity; requests without one valid session header use load-aware unscoped routing and do not receive sticky affinity. Claude Desktop traffic normally follows the unscoped path.

Stopping / removing Desktop interception

cc-router client stop-desktop    # Stop the interceptor (keep configuration)
cc-router client disconnect      # Stop + remove all client config

How it works under the hood

Claude Desktop
     │
     │  tries to connect to api.anthropic.com:443
     ▼
mitmproxy (local mode)
     │  addon.py rewrites scheme/host to CC-Router
     ▼
CC-Router :3456 ──► api.anthropic.com  (with OAuth Bearer token)

mitmproxy's local mode is process-scoped — it only intercepts traffic from the Claude process, not your browser, curl, or any other app. The OS-level interception uses:

Platform Mechanism
macOS Network Extension (App Proxy Provider API)
Windows WinDivert (WFP kernel driver)
Linux eBPF (kernel ≥ 6.8)

Troubleshooting

  • macOS: "provider rejected new flow" — re-enable Mitmproxy Redirector in System Settings → General → Login Items & Extensions → Network Extensions, then restart mitmproxy.
  • Windows: UAC prompt every start — expected; mitmproxy's redirector needs admin at runtime.
  • Linux: "eBPF program failed to load" — check your kernel version with uname -r. You need ≥ 6.8.
  • Chat shows "failed to connect" — make sure CC-Router is reachable from the mitmproxy process. Run curl http://localhost:3456/cc-router/health to verify the proxy is up.

Reverting to normal Claude Code

To stop using cc-router and go back to normal Claude Code authentication:

cc-router revert

This stops the proxy process, removes the auto-start service (if installed), and removes cc-router's settings from ~/.claude/settings.json. Claude Code will use its own authentication on the next launch.

For a gentler approach, cc-router stop interactively asks what you want to clean up.

The dashboard is also a control surface. In local mode it controls the local proxy; in client mode it controls the remote CC-Router configured by cc-router client connect. Authenticated account views include dynamic model-scoped allowance rows, their reset times, applicable global or requested-model cooldowns, paid-extra state, and whether the usage snapshot is fresh, stale, or unavailable. A stale row is shown as unknown rather than as authoritative available capacity.

Key Action

n Add a Claude account
e Enable/disable selected Claude account
w / s Change selected Claude account weekly/session cap
d Delete selected Claude account
m / r Load or refresh discovered provider models
c Set selected anthropic/* model as Claude default
o Set selected openai/* model as OpenAI default

List and change models without waiting for a package update:

cc-router models list
cc-router models set --claude-model anthropic/claude-sonnet-4-6
cc-router models set --openai-model openai/gpt-5-codex

When the proxy is running, models set updates the live router and persists the new defaults. If the proxy is offline, it writes the configuration for the next start.


Security

  • Tokens are stored locally in ~/.cc-router/accounts.json, never in the repository
  • The file is excluded by .gitignore
  • Writes are atomic (write to .tmp, then rename) — no corruption on crash
  • Keychain reads use execFile with a fixed argument array — no shell injection
  • Anonymous opt-out telemetry via Aptabase (see Telemetry below)

See docs/security.md for details.


Telemetry

CC-Router sends a handful of anonymous lifecycle events to Aptabase (privacy-first, open source, EU-hosted). The goal is simple: know how many people use the project, which versions are live, and roughly how many instances are running — so we can prioritize fixes and features.

What we send — the entire payload lives in src/utils/telemetry.ts, audit it yourself:

Event When Custom props
app_started First proxy start after install first_run: true
setup_completed Setup wizard finishes successfully account_count
proxy_started Each cc-router start account_count, mode
proxy_heartbeat Every hour while the proxy is running uptime_minutes, account_count
telemetry_disabled When you run cc-router telemetry off

Plus anonymous system props with every event: appVersion, osName (macOS/Linux/Windows), osVersion, locale, engineVersion (Node), and an anonymous installId (random UUID generated on first run, stored in ~/.cc-router/telemetry.json).

What we never send: IPs, OAuth tokens, account names, request content, prompts, responses, URLs, hostnames, usernames, file paths — nothing that could identify you or your usage patterns.

Disable it — three ways, any one works:

# 1. Persistent opt-out (recommended)
cc-router telemetry off

# 2. Respect the de-facto standard (honored by many OSS tools)
export DO_NOT_TRACK=1

# 3. Project-specific override
export CC_ROUTER_TELEMETRY=0

Check status anytime: cc-router telemetry status.
