Using BrowserSync and Safari for testing your responsive website

Testing a responsive design on an actual device can be quite annoying when you’re down to the point of refining the design and making it more appropriate to such a small screen. As it’s usually testing and refining the best you can locally, then checking on the device through whatever means you usually do it.

I want to show you a way to do that without the inconvenience of having to get it onto the device. It’s not perfect but it really helps speed up the process, which is what matters here.

Unfortunately this approach is Mac only. As we will be using Safari and Xcode.


While this isn’t a completely necessary step to this process, it’s a valuable tool due to the asset updating without reloading it offers. I’m assuming you have installed something by NPM before and are comfortable with terminal. However if you haven’t the BrowserSync website has a guide.

Go to your site files

Firstly open terminal and navigate to your folder which your websites files are contained in. For example

cd ~/Dropbox/Sites/lily

However an easy way to do this is if you’re less comfortable with terminal is by typing cd and dragging the folder to the window and it will place the path for you.

Get BrowserSync running

Depending on your setup, you can run the following in terminal.

browser-sync start --proxy "" --files "css/*.css"

Replace with whatever your site is, it could be localhost, there are further instructions on the website.

After running it you’ll be presented with this, then a browser tab should open immediately. That’s great, now to get it onto your iOS device, you will want to enter the external URL into Safari.

You can use Grunt or Gulp too

If you decide to run it through Grunt or Gulp.


It’s the only way I’m aware of (that’s free) that you can connect to your iOS device. You’ll need to do the following:

Once you reach this point you should see your device listed under the develop menu.

Choose your device and you should get an inspector window.


On the device as you navigate through elements in the inspector you should see it highlight on your device. You can modify styles as you would on your browser normally. Update something in your CSS file in your editor and save, you should see it refresh the styles everywhere.


If you have Xcode installed on your computer you can use the iOS simulator within that to test in the same way (it’s free on the Mac App Store). However you don’t need the external address for this you can use the local URL.

Following the same method as earlier, you can see the iOS Simulator under the develop menu.

Device vs Simulator

If you don’t have an iPhone or iPad the simulator is a great way to test and also adds more convenience to testing and fixing quickly. The only difference is it doesn’t replace using the device itself because of the way that we use devices over clicking with a fine pointer like a mouse.
