OffRouter

Local-first router for coding agents — use your subscriptions first, API keys as fallback.

V1 Honesty: OffRouter routes delegated work and adds routing guidance through supported hooks. It does not replace your harness's primary model call.

What is OffRouter?

OffRouter is a local routing layer for coding agents such as Claude Code, Codex CLI, Gemini CLI, and Grok Build. It lets you keep using your preferred harness while OffRouter chooses the best configured model or agent runtime for each task.

Routing Priority

Subscription-first: use allowed subscription capacity before spending through API keys.
Local/private capacity: run models on your own hardware when policy or sensitivity requires it.
API-key fallback: explicit, audited fallback when subscription routes are unavailable.

Install

npm install -g @offrouter/cli

Requires Node.js 22 or later. See the quickstart guide for setup.

Quick Start

offrouter init        # detect harnesses, check readiness
offrouter doctor      # diagnostics
offrouter login       # sign in to providers
offrouter install claude --profile claude-personal
offrouter mcp serve   # start delegation server

Why OffRouter?

Privacy-first: telemetry-off by default, audit logs stored locally, never sent anywhere unless you explicitly share them.
Deterministic policy: routing rules are explicit, not opaque. Classifier output is a signal, not a decision.
Profile safety: personal profiles only. Work profiles are denied by default.
Provider agnostic: subscription-backed, local runtimes, or API-key — adapters are isolated per provider.
