Shunt Claude Code to any model.

shunt is a spec-compliant Claude Code LLM gateway: a transparent proxy that, for the models you map, diverts inference to another LLM provider at the inference layer. It routes by the request's model id — everything else passes through to Anthropic unchanged (the "shunt"; the fallback is configurable via server.default_provider).

The name is the mechanism: an electrical/railway *shunt* diverts a selected part of the flow onto a parallel path. Here, a mapped model's inference is diverted to another provider while Claude Code's tools and skills stay intact.

Providers for OpenAI, ChatGPT/Codex, xAI, Grok, Cursor, Kimi Code, Zhipu, MiniMax China, OpenCode Zen, Cheaper Inference, Gemini, Antigravity, and Anthropic passthrough ship built in — several of them reusing a subscription you already pay for. Any Anthropic-Messages-compatible backend is one config table away, with no code changes. See Providers.

shunt is pre-1.0 software under active development. Per SemVer, 0.x releases may include breaking changes to configuration keys, the CLI, and behavior — check the release notes before upgrading.

Install

New versions are distributed through Homebrew and prebuilt binaries (macOS/Linux, arm64/x64) attached to each GitHub release; the crates.io package stops at the last version published there. See Installation for prebuilt-binary and from-source instructions.
