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

OAuth Providers

Access Gemini, Codex, Antigravity, Qwen, and iFlow via browser OAuth - no API keys needed

API Profiles

Bring your own keys for GLM, Kimi, or any OpenAI-compatible endpoint

​
Why CCS?

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

​
Task-Appropriate Model Selection

ModelBest For
Claude Sonnet 4.5Complex architecture, system design, debugging
Claude Opus 4.5 ThinkingExtended thinking, difficult problems
OpenRouter (300+ models)Unified access, model variety, cost flexibility
GLM 4.6Simple fixes, routine implementations, docs

Qwen3 CoderCode-focused tasks

​
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
