Often, as a web designer, you use the application Notepad (Or even Notepad ++) as your primary tool for making HTML mockups and store them locally. It may have the disadvantage of having your folders and files lying on his machine, most often on the desktop, and taking up space. Moreover, this solution is not durable either. Imagine Your Harddrive breaks down, or you lose your laptop in any way - all your files (HTML Mockups), representing some kind of value is then lost and important working hours are wasted.


Mockitup online is intended as a successor of Notepad and works as an online HTML editor. Rather than having countless files and folders lying around anywhere, this tool provides the perfect storage for such files, folders, and images.

From time to time a web designer needs to either test tiny HTML or JavaScript snippets in order to build these into even greater projects. A web designer could also have the need for presenting some HTML Mockups for an associate, customer or something similar.

Mockitup fulfils all these needs. FOR FREE.

If you choose to create an account, either by using one of your social media logins, or by creating a new one, you will get some extended features such as: Drag and drop support, extended choice of file types, no adds ect.
