Comparison of free and paid Chrome Developer Tools
While there is nothing wrong with using the free Chrome Developer Tools, it is a personal decision each one must make based on what task they need to execute.
However, let’s compare both and see which one will be most beneficial in the long run:
One reason why most people choose free Chrome Developer Tools over the paid versions is that they cost virtually nothing to use them.
Unlike the paid versions where you have to get our credit card details ready before you can use them, all you have to do with the free version is get a credible link and just start using them.
So in terms of cost, it is profitable to use the free version.
As expected, free versions will have fewer features as compared to using paid versions of Chrome Developer Tools.
In most cases, they don’t just have more features, these features are also user-friendly.
Some Chrome Developer Tools offer tutorial videos where new users can get visual help on how to navigate through its amazing features.
So, in terms of features, it pays to use paid Chrome Developer Tools.
Most paid DevTools are versions that are compatible with various electronic and mobile devices.
We shouldn’t expect anything below that for the money we paid.
This is unlike free versions that may have just one version.
So in terms of availability on several versions, it is better to use pad Chrome Developer Tools.
