deepclaude is an open-source wrapper that redirects Claude Code's API calls to cheaper backends like DeepSeek V4 Pro, OpenRouter, or Fireworks AI instead of Anthropic. It works by setting environment variables per-session so Claude Code's full tool loop (file editing, bash, git, subagents) runs unchanged, but model inference costs drop by up to 17x. DeepSeek V4 Pro at $0.87/M output tokens vs Anthropic's $15/M, with automatic context caching making agent loops even cheaper. A remote control mode with a local proxy splits WebSocket bridge traffic (still Anthropic) from model API calls (routed to the cheaper backend). Limitations include no image/vision support, no parallel tool use, and no MCP server tools through the compatibility layer.
