9Router is an AI gateway that routes requests from coding tools to multiple AI providers while reducing token consumption and managing rate limits.

The tool addresses the problem of expensive AI subscriptions, rate limiting, and token waste by acting as a proxy layer between coding assistants and AI providers. It compresses tool output content to save tokens, automatically falls back between subscription, cheap, and free providers, and supports round-robin distribution across multiple accounts. The approach works by intercepting API requests and routing them through 40+ providers offering over 100 models, allowing developers to maximize their existing subscriptions and access free tier services without manual switching.

Developers should choose this tool if they use multiple coding assistants like Claude Code, Cursor, Cline, or Copilot and want to consolidate access to different AI providers. It suits projects where token efficiency matters and where developers want to avoid hitting rate limits or subscription quotas. The tool works universally with any CLI tool that supports OpenAI-compatible APIs, making it agnostic to the specific coding environment.

The project maintains a substantial base of real-world adopters, as evidenced by most open issues being raised by outside users rather than the core team. Maintainers typically respond to new issues and pull requests within a day.
