Framer supports animation and interaction prototyping for multiple devices, ranging from desktop apps to web apps and mobile platforms. There are already 8 pre-installed devices to choose from, or developers can create their own setup quickly.
As the interface is very clean and simple, it enables you to create interactions by combining objects, triggers and responses just like that. No need for wireframing or shitty mockups, just get to hi-fi prototyping right away.
