## 🚀 Key Advantages

### 1. Blazing Fast Speed
Rayu is built on high-performance streaming architectures, eliminating the typical latency bottlenecks of traditional CLI tools. Our terminal UI utilizes a custom React/Ink renderer with zero-GC cell buffers, and our Go gateway ensures sub-millisecond routing overhead. 
- **Time-to-first-token:** Under 500ms for cached sessions and 1-2s for cold boots. 
- No more waiting on sluggish web bridges or processing screens.

### 2. Peer-to-Peer (P2P) Collaboration
Rayu is the only CLI agent with native P2P capabilities. Collaborate directly with team members in real-time without sending intermediate payloads to external cloud storage. This is ideal for secure enterprise environments, air-gapped systems, and lag-free cooperative terminal sessions.

### 3. Absolute Privacy: No Training Data
While other platforms use your inputs and proprietary source files to train their models, **Rayu never trains on your code**.
- **BYOK (Bring Your Own Key):** Connect directly to your preferred API keys.
- **Hosted Gateway:** Completely transparent proxy pipelines with zero-data-retention guarantees.

### 4. Flawless Execution & Freedom of Choice
Rayu works perfectly right out of the box. Switch models instantly mid-session with `/model` or run parallel diagnostics on your codebase across multiple LLM providers (Anthropic, DeepSeek, Google Gemini, OpenAI, Kimi, and locally hosted models via Ollama/LM Studio).

## 💻 Quick Start

Install globally:

```bash
npm install -g @rayu-dev/rayu-cli
rayu
```

Or run instantly without installing:

```bash
npx @rayu-dev/rayu-cli
```

On first launch, Rayu will guide you through connecting a provider. Choose BYOK (your own API key) or a Rayu-hosted connection.

## 🌐 Monorepo Services

Rayu consists of four independent services. They work together or as individual standalone configurations.

| Directory | Stack | Role |
|-----------|-------|------|
| [`rayu/`](./rayu/) | TypeScript + Bun + Ink | **The CLI** — AI coding agent itself |
| [`rayu-backend/`](./rayu-backend/) | NestJS + Prisma + MySQL | **Accounts API** — auth, plans, billing |
| [`rayu-gateway/`](./rayu-gateway/) | Go + chi + Redis | **AI Gateway** — streaming proxy, rate limiting |
| [`rayu-web/`](./rayu-web/) | Next.js 15 + NextAuth | **Website** — marketing site + user dashboard |
| [`deploy/`](./deploy/) | Docker Compose + Caddy | **Production** — single-VPS deployment stack |

## 🛠️ CLI Quick Commands

```bash
cd rayu && bun install && bun run dev       # Run CLI from source
cd rayu-backend && npm install && npm run start:dev   # Launch accounts backend
cd rayu-gateway && go run ./cmd/gateway      # Run gateway routing proxy
cd rayu-web && npm install && npm run dev    # Spin up web dashboard
```
