9Router is a free AI router and token saver designed to address the cost and efficiency bottlenecks developers encounter during coding. It utilizes intelligent routing and RTK compression technology to automatically distribute requests to subscribed, low-cost, and free models, while optimizing tool output content, potentially saving 20-40% of token consumption.
Usage is straightforward: after a global installation, start the service, configure free or paid AI providers (e.g., Kiro AI, OpenCode Free) in the web dashboard, then point the API endpoints of your commonly used AI coding tools (such as Claude Code, Cursor, Cline, etc.) to 9Router's local address.
It is ideal for developers who need continuous AI-assisted programming but are constrained by a single provider's quota, cost, or rate limits. Whether you're an individual developer, student, or small team, 9Router helps maximize the utility of existing subscriptions and seamlessly switch to more economical models within budget.
For first-time users, it's recommended to connect a free provider (like Kiro AI) from the dashboard for a quick trial. Note that 9Router itself is a routing proxy; its ultimate effectiveness depends on the quality and availability of the configured backend AI providers.
Key Features
The core differentiator is the integration of the RTK Token Saver, which automatically compresses tool output (e.g., git diff, grep results) to significantly save tokens. Simultaneously, it provides a three-tier automatic failover routing system based on quota and cost (subscribed → low-cost → free), ensuring uninterrupted service, whereas similar tools typically only perform simple load balancing or routing.
Limitations
Not suitable for production environments with a strong dependency on a specific, single AI provider (e.g., exclusively the official OpenAI API) or those extremely sensitive to latency.
FAQ
Is 9Router free?
The 9Router software itself is free and open-source, but usage requires backend AI providers. It supports connecting to a variety of free, low-cost, and paid models.
Which AI coding tools are supported?
It supports any CLI or IDE tool configurable via a custom API endpoint, such as Claude Code, Cursor, Cline, Antigravity, OpenClaw, Codex, and more.
