Welcome to CCS

CCS (Claude Code Switch) is a CLI wrapper that enables instant switching between multiple Claude accounts and alternative AI models. Run multiple Claude subscriptions simultaneously, use OAuth providers like Gemini and Codex, or bring your own API keys.

​
The Three Pillars

Multiple Claude Accounts

Run work, personal, and team Claude accounts simultaneously with isolated sessions. Optional shared context groups.

OAuth Providers

Access Gemini, Codex, Copilot, Kiro, Antigravity, Qwen, and more via OAuth - no API keys needed

API Profiles & Local Models

Bring your own keys for Claude, Z.AI GLM, Kimi for Coding, Novita, Alibaba, or run local models via llama.cpp

​
Why CCS?

Built for developers with both Claude subscription and alternative model access.

​
Rate Limit Management

No more manual config editing when Claude hits rate limits: 
ccs           # Using Claude, hit rate limit
ccs glm       # Switch to GLM instantly
ccs gemini    # Or use Gemini via OAuth
ccs           # Switch back when limit resets
ccs glmt is deprecated and no longer marketed as a supported surface. Use ccs glm for Z.AI API profiles and ccs km for reasoning-first Kimi API profiles.
