askalf/dario

One local endpoint that routes Claude Code, Cursor, Cline, Aider, Codex CLI and the SDKs through the Claude and ChatGPT plans you already pay for: seats first, then the fallback chain you configure, and a ledger of who paid. Zero runtime dependencies.

What it solves

Many AI coding tools (like Cursor, Aider, or Cline) require individual API keys and charge per-token usage fees, even if you already pay a monthly subscription for Claude or ChatGPT. This project allows you to use your existing subscriptions as a backend for these tools, avoiding redundant billing and per-token costs.

How it works

dario runs as a local proxy server on your machine. You point your AI tools to http://localhost:3456 instead of the official API endpoints. It intercepts the requests, authenticates them using your existing Claude or ChatGPT login, and forwards them to the respective service. It also handles failover between subscriptions if you hit rate limits.

Who it’s for

Developers who use multiple AI-powered coding assistants and want to consolidate their usage under their existing monthly subscriptions rather than paying for multiple API-based services.

Highlights

  • Unified Endpoint: Routes all compatible AI tools through one local URL.
  • Subscription-Based: Uses your existing Claude or ChatGPT plans instead of per-token API billing.
  • Failover Support: Automatically switches between subscriptions if one hits a rate limit (429).
  • Zero Telemetry: The project runs entirely on your local machine and does not phone home.
  • Broad Compatibility: Works with Claude Code, Cursor, Aider, Cline, Continue, Zed, and many others.
