Once you create your account on Raklet, you'll get a standard look and feel. This was intentionally left clean and clear. It's up to you to change this or not.
You can easily customize your account. Changing button or header background colors, choosing your own font, etc. can be done with adding couple of lines of CSS. You can add your Custom CSS on Settings > Custom CSS page.
You can see some examples of customized Raklet platforms below:
CSS - for a personalized look and feel, updated header, button colors, custom fonts, ...
JS - for added interactions (show/hide field, update navigation, ... )
