A command-line tool for seamlessly switching between multiple LLM providers

🌍 Languages: English | 中文 | 日本語 | 한국어 | Français | Deutsch | Español | Русский | العربية

Seamlessly switch between LLM providers without affecting your native Claude Code setup. Isolated configuration with official best practices from model providers.

💡 Why LLM Switcher?

🔒 Isolated Configuration Environment

• Zero impact on native Claude Code: Your original Claude setup remains untouched
• Per-session provider switching: Each terminal session can use different providers

🎯 Official Best Practices

• Provider-recommended configurations: Following official integration guidelines from each provider
• Claude Code dual-model configuration: Main model for conversation/planning/code generation/complex reasoning, fast model (Claude uses Haiku e.g. 3.5 Haiku) for file search/syntax checking and auxiliary tasks - intelligently optimizing performance and cost
