9router: The Vibecoder's Wet Dream for AI Coding
If you're fully bought into the vibecoding lifestyle—living in Cursor, letting Claude Code drive your terminal, or having Cline architect your entire backend while you just guide the vibes—you already know the two massive buzzkills that ruin the flow state:
1. The "429 Too Many Requests" Wall: Hitting rate limits right when you're in the zone.
2. The Token Tax: Going broke because your agent decided to cat a 5,000-line minified JSON file or git diff your entire node_modules folder, torching your context window and your wallet.
Enter 9router (https://github.com/decolua/9router). It’s an open-source local proxy that sits between your AI coding tools and your API providers, and it is absolute godsend for maintaining the vibe.
Here is why it's the ultimate vibecoder tool:
1. The RTK Token Saver (Compression Magic)
Vibecoding generates a lot of noise. When your agent runs terminal commands (ls, grep, git diff), the raw output eats massive amounts of tokens. 9router intercepts these tool results and seamlessly compresses them before they hit the LLM. You save 20–40% on input tokens, which means your context window stays
pristine for actual code, and your API bill drops drastically.
2. Caveman Mode: Shutting the LLM Up
Nothing kills the vibe faster than an LLM writing a three-paragraph essay about how excited it is to help you update a CSS class. Caveman Mode intercepts prompts and forces the LLM to use ultra-terse, hyper-technical language. You just get the code and the diffs. It saves up to 65% on output tokens and makes
your agents feel infinitely faster and less annoying.
3. Zero-Downtime Smart Routing
When your Claude Pro runs out of juice, the vibe usually stops. 9router fixes this with a smart 3-tier fallback system:
* Tier 1: Your premium keys (Claude, OpenAI).
* Tier 2: Cheap, fast high-throughput models (DeepSeek, MiniMax) when Tier 1 rate-limits.
* Tier 3: Free providers (OpenCode, Kiro) as a last resort.
It seamlessly routes the traffic. You never see an error; the agent just keeps coding.
4. Format Translation = Zero Friction
Want to use Gemini 2.0 or a weird local Ollama model in a tool that only supports OpenAI? 9router translates the API formats on the fly. Point your tool at http://localhost:20128/v1, tell it what model you want, and 9router handles the translation.
Get Back to Vibing
It runs locally on your machine and takes 10 seconds to set up:
1 npm install -g 9router
2 9router
Point your AI tool's Base URL to http://localhost:20128/v1 and you're done.
If you want to stop thinking about API quotas and just keep the code flowing, check it out: https://github.com/decolua/9router
