Web, Mobile, Desktop
Fine-grain control for adding interactivity and animations to individual elements.
Advanced support for gesture based interactions.
High fidelity output for animations and interactions.
Ability to import a Sketch file, which brings in all assets as individual objects that can be manipulated in Framer.
Immediately see changes to prototype while working via live viewer (split screen with code on the left and live preview on the right is a powerful way to work).
Thorough documentation available for Coffeescript language.
View prototype on Android, iOS, or web through Mirror app.
Requires a basic understanding of programming languages.
Takes time to get design elements in Sketch file set up correctly for use in Framer.
No visual way to keep track of states and pages; everything is built with Coffeescript.
