The wireframe is so important for the web design process. Obviously it gives us bones to work from when designing the site, but it really helps the client too. Content development is almost always a bottleneck, so giving the client something visual early in the process usually helps them as they gather content on their end.
We currently use Adobe XD to create our mockups and site designs. It's a cool program that allows us to create live prototypes of the user experience before going to development. Hope you enjoy!
