Prototyper

What Is Prototyper?

Prototyper is a paid Figma plugin in the design-tools category that enables designers to bring designs to life through coding capabilities directly within Figma. It extends Figma's native prototyping by allowing the creation of interactive prototypes using JavaScript, supporting both simple animations and complex interactions without leaving the design environment. Prototyper fits into the design workflow after initial UI mockups, where designers need to simulate realistic behaviors before handing off to developers.

What Prototyper Does

• Generates interactive prototypes using JavaScript code integrated into Figma frames.
• Supports game controller and keyboard navigation prototyping based on element arrangements.
• Automatically assigns interactions, such as left-right navigation for horizontally aligned elements.
• Enables creation of sliders, viewports, and other dynamic UI components with coded logic.
• Runs locally in Figma files without network calls, ensuring data privacy.
• Provides open-source access for customization and contributions.

How Prototyper Can Be Used

• Designers prototype game UI elements like inventories, skill trees, or quest logs by selecting frames and running Prototyper to add navigation inputs in seconds.
• Create slider interactions by duplicating frames, adjusting element positions, and applying JavaScript via the plugin for smooth handle movement.
• Build viewport components for app interfaces, linking prototypes to simulate scrolling or state changes during user testing.
• Test keyboard-driven flows in prototypes for desktop or console applications, verifying navigation logic matches final product behavior.
• Iterate on micro-interactions, such as button states or transitions, using code to preview realistic animations in Figma's prototype mode.

Who Is Prototyper For?

Prototyper serves UI designers and prototypers working on interactive applications, particularly game interfaces or keyboard-navigable experiences, who require more advanced control beyond Figma's built-in tools. It suits teams at studios like PlayStation, Riot Games, or Blizzard, where realistic prototypes reduce developer guesswork. Experience levels range from intermediate designers familiar with Figma plugins to advanced users comfortable with basic JavaScript concepts for custom behaviors. Prototyper works well for projects needing quick, coded interactions in workflows involving handoff to development. Visit Prototyper
