dario

A local LLM router. One endpoint, every provider.
Runs on your machine. Unifies OpenAI, Groq, OpenRouter, Ollama, vLLM, LiteLLM, any OpenAI-compat URL, and your Claude Max subscription (via OAuth) behind one endpoint at http://localhost:3456. Speaks both the Anthropic Messages API and the OpenAI Chat Completions API, so your tools stop caring which vendor is upstream. Drops in under the Claude Agent SDK as an API-key-compatible backend.

Zero runtime dependencies. SLSA-attested on every release. Nothing phones home. Independent, unofficial, third-party — see DISCLAIMER.md.

30 seconds

# 1. Install
npm install -g @askalf/dario

# 2. Log in to your Claude Max subscription
dario login                      # or `dario login --manual` for SSH / headless setups

# 3. Start the local Claude API proxy
dario proxy

# 4. Point any Anthropic-compat tool at it
export ANTHROPIC_BASE_URL=http://localhost:3456
export ANTHROPIC_API_KEY=dario

Done. Every tool that honors those env vars — Claude Code, Cursor, Aider, Cline, Roo Code, Continue.dev, Zed, Windsurf, OpenHands, OpenClaw, Hermes, the Claude Agent SDK, your own scripts — now routes through your Claude Max subscription instead of per-token API pricing, because dario sends the same request shape Claude Code itself sends, which is the shape the subscription-billing path recognizes.

For OpenAI / Groq / OpenRouter / Ollama / LiteLLM / vLLM, add one backend line and reuse the same proxy:

dario backend add openai     --key=sk-proj-...
dario backend add groq       --key=gsk_...    --base-url=https://api.groq.com/openai/v1
dario backend add openrouter --key=sk-or-...  --base-url=https://openrouter.ai/api/v1
dario backend add local      --key=anything   --base-url=http://127.0.0.1:11434/v1

export OPENAI_BASE_URL=http://localhost:3456/v1
export OPENAI_API_KEY=dario

Switching providers is a model-name change in your tool — claude-opus-4-7, gpt-4o, llama-3.3-70b, any OpenRouter / Groq / local model — not a reconfigure. Force a specific backend with a prefix: openai:gpt-4o, claude:opus, groq:llama-3.3-70b, local:qwen-coder.

Something not right? dario doctor prints a single paste-ready health report. Paste that when you file an issue.
