Apple provides built-in dеvеlopеr tools for the Safari browser that come with robust capabilities for improving the quality of wеbsitеs and wеb applications. The developer tools for Safari support thе latеst wеb tеchnologiеs out of thе box, ranging from dеbugging JavaScript to auditing web pеrformancе.

In this article, we look at how to debug websites using Safari Developer Tools. But before that, let’s check out why it’s vital to debug websites on Safari.
Let’s dive in!

Why debug websites on Safari?

Safari has been a part of the most popular browsers since 2003. Its first version was released the same year with Mac OS X Panther. Since the iPhone launched in 2007, a mobile version of Safari has been included in all iOS devices. If a user doesn’t change it, it’s the default browser on Apple devices.

Considering the number of Apple devices and their never-ending versions, the combinations of different features and screen resolutions are enormous. But when you debug websites on Safari before launch, your users can hop on to the Window that quickly takes them to your services and products.

Web developers must validate website appearance across different screen sizes to maintain cross browser compatibility. This ensures the correct rendering of web pages across various browsers. It also provides a comparatively superior user experience with consistency. It’s also essential to consider how a particular version of Safari might interact with a device’s hardware specifications. This adds to another form of verification that is crucial for the web development pipeline.

Once you go ahead and launch a website, debugging it after encountering a bug becomes almost impossible. That’s why it’s crucial to debug websites for Safari before they go live. After all, vulnerability, compromised navigation, and other incompetencies can turn a simple user interface into a screaming nightmare. Now, let’s see what Safari Developer Tools are and how they can help in the debugging process and ensure your websites are bug-free.
