What is Prototype Composer?

Prototype Composer is a free and open-source user interface design and prototyping tool. It allows designers and developers to quickly sketch out user interface ideas and concepts and turn them into interactive prototypes. It includes features for:

  • Drawing vector shapes and adding images
  • Creating artboards to organize layout ideas
  • Code output of designs in HTML, React, Angular and other web frameworks
  • Creating interactive prototypes with transitions, taps and swipes
  • Collaboration tools to share designs and get feedback
  • Exporting final designs to PNG, JPG, SVG and PDF

Some key benefits of Prototype Composer are its speed and ease of use for mocking up interfaces, support for the latest web frameworks to turn designs into code, and collaboration features to share and iterate on designs. It's a good option for UI/UX designers, product managers, developers and teams that want to visualize and test interface ideas quickly without needing advanced coding skills.
