How to Build a Prototype in Figma

Interactions, overlays, variables, smart animate - the Figma prototype that gets real feedback without a line of code.

A Figma prototype is the cheapest test of a design decision. It replaces weeks of engineering with hours of design work and gets real user feedback before a single line of code is written. This guide covers the interaction types, fidelity decisions, and testing setup that make Figma prototypes useful.

No fluff. Real craft from designers who ship products people love using.

The Fidelity Decision: Lo-Fi vs Hi-Fi Prototype

Lo-fi prototype (wireframe quality): use when testing information architecture, navigation structure, or flow logic. Users focus on structure not aesthetics. Takes hours to build. Right for early validation. Hi-fi prototype (pixel-perfect): use when testing visual design, micro-interactions, or brand perception. Takes days to build. Right for stakeholder presentation or final usability test before launch. The middle ground most teams miss: a medium-fidelity prototype with real content but simplified visual design. It validates flow and content without the overhead of full visual production.

At Valletta Software, we focus on:

Connection types: on click on hover after delay - match the intended interaction type

Overlays: bottom sheet modal toast - prototype them as overlays not separate frames

Smart animate: use matching layer names for smooth transitions between frames - feels native

Variables: Figma variables for interactive states (checkbox toggle counter) - no more duplicate frames

Scrollable frames: set scroll behavior per frame - vertical horizontal fixed header

Prototype flow: name your flows - multiple user journeys in one prototype

Sharing: share with view-only link comment mode for async stakeholder review - no Zoom required

The Prototype Testing Setup That Gets Useful Feedback

A prototype without a test plan is a demo. A prototype with a test plan is research.

We give you more than just people. We give you top performers who drive results.

Test tasks: 3-5 specific tasks the participant must complete - not open exploration

Starting frame: define the starting screen - not the first frame in the file

Error paths: prototype at least one error state per critical flow - not just happy path

Device preview: test on actual device using Figma mobile app - not a laptop browser

Observation mode: facilitator watches on a second screen without joining the call

Recording: Zoom or Loom record consent first - for synthesis after the session

Insight notes: stop after 3 sessions to look for patterns before testing 5 - course correct early

You lead the work. We handle the rest. From EUR 45/h.

How to Build a Prototype in Figma - With Designers Who Test Before They Ship

Lets keep it simple.

Our designers use AI to move faster without cutting corners - Figma AI, Midjourney for moodboarding, automated accessibility checks, and AI-generated copy starters - so the creative energy goes into decisions, not busywork.

Lets keep it simple.

Our designers build Figma prototypes at the right fidelity for the question being asked - and test them with real users before development starts
