I built Huiyu Pi — AI coding agent that starts at ~80 tokens.

I've been frustrated with AI coding tools that load 15K-28K tokens of system prompts before you can even ask a question. The AI spends most of its attention reading the manual, not solving your code.
So I built Huiyu Pi — a self-hosted AI coding agent that starts at ~80 tokens.

What it does:

• Browser-based IDE (no heavy Electron app)
• ~80 tokens system prompt (not 20K)
• ~0.3s first token response
• 90%+ cheaper per request
• 100% local — your code, API keys, conversations never leave your machine
• Multi-LLM: Claude, GPT, DeepSeek, Gemini, Mistral, Groq, xAI, OpenRouter
• Built-in terminal, file editor, Git integration
• PWA support (works on mobile)

How to try:
npx huiyu-pi
Then open http://localhost:9144
Tech stack:

• Frontend: React 19, TypeScript, Vite, Tailwind CSS
• Backend: Fastify, WebSocket, SSE
• Terminal: xterm.js + node-pty

  Would love feedback from the self-hosted community!
