Electron Chromium Inspector

I have a very basic Electron application whith a simple package.json like this: 

{
  "name": "app",
  "version": "1.0.0",
  "main": "main.js"
}

and the main.js file like this: 

const {app, BrowserWindow} = require('electron')
const path = require('path')
const url = require('url')

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let win

function createWindow () {
  // Create the browser window.
  win = new BrowserWindow({width: 800, height: 600})

  // and load the index.html of the app.
  win.loadURL(url.format({
    pathname: path.join(__dirname, 'index.html'),
    protocol: 'file:',
    slashes: true
  }))

  // Open the DevTools.
  win.webContents.openDevTools()

  // Emitted when the window is closed.
  win.on('closed', () => {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    win = null
  })
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow)

// Quit when all windows are closed.
app.on('window-all-closed', () => {
  // On macOS it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('activate', () => {
  // On macOS it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (win === null) {
    createWindow()
  }
})

But when I start the app the chromium's inpector apear in the screen together with my index.html page. Why the inspector apear automtically?

It isn't technically called the "Inspector", but the "DevTools", short for "Developer Tools" on Chromium. The reason it's opening on app startup is because you are opening the DevTools with this line:

win.webContents.openDevTools()

BrowserWindow.webContents is documented here, with the description of openDevTools:

contents.openDevTools([options])

Opens the devtools.

Remove this to stop the DevTools from opening.
