Connect Claude Code in three minutes

CoreCode is a pure Claude relay: requests go straight to official Anthropic Claude accounts. No model swaps, no other models mixed in, and each session stays on one account, so prompt caching hits reliably. CoreCode also serves OpenAI GPT, Google Gemini and xAI Grok, each in its own group.
