Overview

Claude Dev is a VS Code AI coding extension suited for Claude-style code explanation, refactoring suggestions, and multi-turn collaboration through Crazyrouter. For public docs, prefer the OpenAI Compatible route first because it is more consistent with the rest of the Crazyrouter integration stack and easier to troubleshoot.
The https://crazyrouter.com/v1 URL on this page applies only to Claude Dev’s OpenAI Compatible provider. Do not copy it into Claude Code’s ANTHROPIC_BASE_URL; Claude Code should use the root domain https://crazyrouter.com or https://cn.crazyrouter.com.
