CC-Switch is a cross-platform desktop application built with Tauri 2.8 (Rust) and React 18 that unifies management of Claude Code, Codex, OpenCode, and Gemini CLI configurations in a single interface. It provides one-click provider switching, MCP server management across multiple transport types (stdio, HTTP, SSE), a skills management system with auto-scan from GitHub repositories, and multi-preset system prompt editing with real-time Markdown preview. The v3.10.0 update added OpenCode as the fourth supported CLI, global proxy settings, and per-provider configuration options. Features AWS Bedrock support with cross-region inference and a SQLite + JSON dual-layer architecture designed for future cloud sync.
