Design app mockups faster than you can describe them.

TapUi Studio gives product teams a lightweight, balsamiq-inspired canvas for sketching flows, screens, and responsive layouts. Drag elements onto the board, connect screens together, and export structured JSON for every breakpoint without touching a single Razor post.

Design at the speed of thought

Canvas

Drag, drop, and flow

Build screens like you are sketching in a notebook. Every element is absolutely positioned and draggable, so you can explore layout ideas without fighting a rigid grid or box model.

Components

Starter library included

TapUi ships with labels, buttons, icons, cards, lists, badges, inputs, navigation bars, and more. Mix and match components to compose flows for mobile, tablet, and web breakpoints in minutes.

Data

Structured JSON output

Under the hood every view is stored as JSON with coordinates, geometry, and properties. Copy the JSON for prototypes, handoff packages, or automation workflows straight from the inspector.

A workflow built for product teams

1
Create a project

Organize related screens under projects like “Mobile onboarding” or “Dashboard refresh”.

2
Design each screen

Drop UI elements onto the canvas, tweak their properties, and link interactions to other screens.

3
Publish the JSON

Preview the generated JSON, copy it to your clipboard, or download it for documentation.
