Prototyping & UX

Validate your product
before you build it

High-fidelity prototypes that let you see, test and adjust
the experience before a single line of code is written.

Design before code

Building without prototyping is expensive. Changing a screen in Figma costs minutes; changing it after it's been coded costs weeks. The prototype isn't decorative — it's the cheapest way to be wrong and course-correct.

At Tesler we design high-fidelity prototypes in Figma: navigable, with real states, microinteractions and data that mimic the finished product. Your team, your customers or your investors can use it as if it already existed.

The deliverable is useful to validate with users, align the team, pitch to investors and kick off development with zero ambiguity. Whether your tech team is internal or external, they receive a file ready to implement: components, variants, styles and specifications.

Figma prototype example

What we design

From idea to technical handoff, every deliverable is built to reduce risk and drive decisions backed by evidence.

Research & flows

User research, task mapping and user flows. The foundation everything else rests on.

Wireframes

Structure and information architecture before visual design. We validate logic before aesthetics.

High-fidelity prototypes

Finished screens, real interactions, error and loading states. Navigable like the final product.

User testing

Sessions with real users: observation, task-success metrics and actionable findings.

Product design system

Components, variants and tokens so the product scales without losing consistency.

Technical handoff

File ready for the dev team: specs, assets and behaviour documentation.

Projects we prototype

Mobile app

Full flows, microinteractions and real states.

SaaS web

Panels, dashboards and management flows for digital product.

Interactive landing

Navigable prototype to validate message and structure before the final site.

E-commerce checkout

Purchase flow tested with users before going to production.

Design system

Reusable components, tokens and documentation in Figma.

User testing

Guided sessions, metrics and actionable findings.

Dev handoff

File ready for your tech team to implement without questions.

Why prototype

The prototype is the smallest investment you can make to avoid the most expensive mistakes.

Less risk

Test the idea in hours, not months. If something doesn't work, you know before spending the dev budget.

Better conversion

Adjustments made on real usage evidence produce products that convert and retain better.

Aligned team

Everyone, from marketing to dev, sees the same thing. No more "I thought it worked like this".

Faster development

With the prototype ready, your dev team implements without stopping every other day to resolve design questions.

Our process

From hypothesis to navigable file

01

Research

We understand user, tasks and context of use. We define hypotheses to validate.

02

Wireframes

Structure and flows in low fidelity. We iterate fast on logic before visual design.

03

High fidelity

Visual design, components, states and microinteractions. Fully navigable prototype.

04

Testing & handoff

User testing, final adjustments and delivery ready for the dev team.

Frequently asked questions

A mockup is a static image, like a photo of the product. A prototype is navigable: you can click, fill in forms, see errors and walk through flows as if it were real. It's the only honest way to validate before building.

We focus on design. Development is handled by your internal team or the technical partner you choose. The prototype ships with all the documentation any developer needs to implement it without missing information.

That's exactly the ideal use case. We build the prototype, test it with potential users and hand you evidence to decide whether to move forward, pivot or drop it. The cost is a fraction of what it saves if the idea needs adjustments.

A prototyped landing ships in 1 to 2 weeks. A full app or SaaS flow takes 3 to 6 weeks depending on scope. Includes everything from research to documented handoff.
