CodeRouter

About

Claude Code and Cursor direct all operations through Opus, which costs $75 per million tokens, including actions like reading files and writing commit messages. CodeRouter introduces intelligent, phase-based task routing by identifying your current activity to select the best model. It uses Opus for planning stages, Sonnet or DeepSeek for implementation work, and Flash for testing. This approach reduced costs from $212 monthly to $63. A single URL modification maintains your existing workflow. The tool is compatible with Cursor, Claude Code, Aider, Copilot, and Windsurf. New users receive one million tokens at no cost upon registration.
