DevTunnel+ - Local Developer Tunneling Solution

This repository contains the full source code for DevTunnel+, a powerful alternative to ngrok for exposing local servers to the internet.

Project Structure

The project is split into two main standalone folders:

Folder	Description	Tech Stack
frontend/	The Dashboard UI	React, Vite, Tailwind CSS
backend/	The Gateway Server & CLI	Node.js, Express, WebSocket

---

🚀 Getting Started

You will need two terminal windows to run the full application.

1. Start the Backend (Gateway Server)

This runs the core server that handles all tunnel connections.

cd backend
npm install
npm run dev

Server runs at: http://localhost:3000

2. Start the Frontend (Dashboard)

This runs the UI for inspecting requests and managing tunnels.

cd frontend
npm install
npm run dev

Dashboard runs at: http://localhost:3002

---

💻 Using the CLI

To start a tunnel for your local app, use the included CLI tool from the backend directory.

# In inside the backend folder
npm run cli -- start 8080

(Replace 8080 with the port of your local application)
