Protowire

Protowire is a Sketch plugin that adds prototyping to Sketch. Quickly create prototypes of your mobile app, webapp or website designs. Prototypes can be easily shared with clients and workmates with just a link - no app to download.

Instantly preview your prototype within Sketch or on a device. The design and the prototype can evolve in parallel so you can repeatedly test how your design is working out. Make use of Sketch's resizing constraints to create prototypes that work on any screen size. Prototypes can include tablet and mobile designs so the same prototype can be viewed on a wide range of devices.
