9Router is an open-source AI coding router and token saver that connects various AI coding tools to multiple AI providers, optimizing token usage and providing fallback options.
Source: README View on GitHub →9Router is gaining attention due to its ability to save developers money on AI tokens by providing an efficient routing system that connects to multiple AI providers, including free ones. It addresses the pain points of subscription limits, rate limits, and expensive APIs, filling a gap in the market for cost-effective AI integration.

Source: READMEWorks with a wide range of AI coding tools such as Claude Code, Codex, Cursor, Cline, and more.
Source: READMEThe architecture of 9Router is inferred to be modular, with clear separation of concerns. It likely uses design patterns such as the Proxy pattern for routing requests and the Strategy pattern for handling different AI providers. The data flow involves a central router that interfaces with various AI tools and providers, managing token usage and fallback logic.
