Best practices for 404 page customization

I really confused about when I need to change default 404 page? only when my Laravel apps related to web site?

It is totally up to you! The top 4 results from a Google search yielded:

I suggest take a look and make your own mind up.

You want the forge a like view while you are developing and you want a laravel a like view when you are in production. This way you get a clear message while developing and the user get's a more general but less technical message
