Ideal for

Web, Desktop, Mobile

HotGloo is ideal for prototyping low fidelity wireframes for web, desktop or mobile apps.

Prototype elements must be built within the tool using an existing library or wireframe UI elements. Images of existing mocks can be brought it, but HotGloo was not optimized to work with full-screen mocks.


  • Fine-grain control for adding interactivity to individual elements.
  • Solid library of basic wireframe UI elements with default behaviors.
  • Collaborative features allow multiple people to edit/review a project.
  • Support for responsive design with option to add multiple break points to each page


  • Moderate learning curve; took some time to get oriented as a first-time user.
  • No device-specific templates or features.
  • No support for gesture-based interaction, only support for mouse interaction.
  • Designed to build out screens in the tool. Difficult to use existing mock-ups as starting point (experienced a lot of lag time when working with imported images).
  • No options for adding animated transitions (eg. swipe, fade, etc.).
