decolua/9router

Project overview

9router is a local smart router for AI coding tools that connects them to free, cheap, and subscription model tiers across 40+ providers. It automatically falls back across tiers to prevent downtime and compresses tool outputs to save 20-40% on token usage.

Best for

• Developers using AI coding tools who experience rate limits, want to maximize subscription value, or need to reduce token usage.

Key capabilities

• Automatically compresses tool_result content, such as git diff, grep, and ls outputs, before sending it to the LLM to save tokens.
• Automatically routes requests through configured tiers (Subscription -> Cheap -> Free) to avoid downtime when quotas run out.
• Tracks live token counts and reset countdowns to maximize subscription value.
• Allows adding multiple accounts per provider with auto round-robin or priority-based routing.
• Automatically refreshes OAuth tokens before expiration.
• An optional external proxy to compress context tokens before routing.
• Injects a 'lazy senior dev' prompt to bias the LLM toward minimal, YAGNI-first code.

Limitations and risks

• Using free tier tools with non-CLI tools (e.g., Gemini CLI with Claude) may result in account bans.

Getting started

• Install globally via npm with a single command, run the application, and access the dashboard at http://localhost:20128.
