Windows Users

Download the latest CC-Switch-v{version}-Windows.msi installer or CC-Switch-v{version}-Windows-Portable.zip portable version from the Releases page.

macOS Users

Method 1: Install via Homebrew (Recommended)

brew tap farion1231/ccswitch
brew install --cask cc-switch

Update:

brew upgrade --cask cc-switch

Method 2: Manual Download

Download CC-Switch-v{version}-macOS.zip from the Releases page and extract to use.

Note: Since the author doesn't have an Apple Developer account, you may see an "unidentified developer" warning on first launch. Please close it first, then go to "System Settings" → "Privacy & Security" → click "Open Anyway", and you'll be able to open it normally afterwards.

Linux Users

Download the latest CC-Switch-v{version}-Linux.deb package or CC-Switch-v{version}-Linux.AppImage from the Releases page.

Quick Start

Basic Usage

1. Add Provider: Click "Add Provider" → Choose preset or create custom configuration
2. Switch Provider:
3. Main UI: Select provider → Click "Enable"
4. System Tray: Click provider name directly (instant effect)
5. Takes Effect: Restart your terminal or Claude Code / Codex / Gemini clients to apply changes
6. Back to Official: Select the "Official Login" preset (Claude/Codex) or "Google Official" preset (Gemini), restart the corresponding client, then follow its login/OAuth flow

MCP Management

• Location: Click "MCP" button in top-right corner
• Add Server: Use built-in templates (mcp-fetch, mcp-filesystem) or custom config
• Enable/Disable: Toggle switches to control which servers sync to live config
• Sync: Enabled servers auto-sync to ~/.claude.json (Claude) or ~/.codex/config.toml (Codex)

Configuration Files

Claude Code

• Live config: ~/.claude/settings.json (or claude.json)
• API key field: env.ANTHROPIC_AUTH_TOKEN or env.ANTHROPIC_API_KEY
• MCP servers: ~/.claude.json → mcpServers

Codex

• Live config: ~/.codex/auth.json (required) + config.toml (optional)
• API key field: OPENAI_API_KEY in auth.json
• MCP servers: ~/.codex/config.toml → [mcp_servers] tables

Gemini

• Live config: ~/.gemini/.env (API key) + ~/.gemini/settings.json (auth type for quick switching)
• API key field: GEMINI_API_KEY inside .env
• Tray quick switch: each provider switch rewrites ~/.gemini/.env so the Gemini CLI picks up the new credentials immediately

CC Switch Storage

• Main config (SSOT): ~/.cc-switch/config.json
• Settings: ~/.cc-switch/settings.json
• Backups: ~/.cc-switch/backups/ (auto-rotate, keep 10)

Cloud Sync Setup

1. Go to Settings → "Custom Configuration Directory"
2. Choose your cloud sync folder (Dropbox, OneDrive, iCloud, etc.)
3. Restart app to apply
4. Repeat on other devices to enable cross-device sync

Note: First launch auto-imports existing Claude/Codex configs as default provider.

Core Design Patterns

• SSOT (Single Source of Truth): All provider configs stored in ~/.cc-switch/config.json
• Dual-way Sync: Write to live files on switch, backfill from live when editing active provider
• Atomic Writes: Temp file + rename pattern prevents config corruption
• Concurrency Safe: RwLock with scoped guards avoids deadlocks
• Layered Architecture: Clear separation (Commands → Services → Models)

Key Components

• ProviderService: Provider CRUD, switching, backfill, sorting
• McpService: MCP server management, import/export, live file sync
• ConfigService: Config import/export, backup rotation
• SpeedtestService: API endpoint latency measurement

v3.6 Refactoring

• Backend: 5-phase refactoring (error handling → command split → tests → services → concurrency)
• Frontend: 4-stage refactoring (test infra → hooks → components → cleanup)
• Testing: 100% hooks coverage + integration tests (vitest + MSW)

Development

Environment Requirements

• Node.js 18+
• pnpm 8+
• Rust 1.85+
• Tauri CLI 2.8+

Testing Guide (v3.6 New)

Frontend Testing:

• Uses vitest as test framework
• Uses MSW (Mock Service Worker) to mock Tauri API calls
• Uses @testing-library/react for component testing

Test Coverage:

• Hooks unit tests (100% coverage)
• useProviderActions - Provider operations
• useMcpActions - MCP management
• useSettings series - Settings management
• useImportExport - Import/export
• Integration tests
• App main application flow
• SettingsDialog complete interaction
• MCP panel functionality

Running Tests:

# Run all tests
pnpm test:unit

# Watch mode (auto re-run)
pnpm test:unit:watch

# With coverage report
pnpm test:unit --coverage
