Design UI Independently

Describe the UI in a language akin to HTML/CSS allowing a separation between the presentation layer and business logic.

Designing the UI independently speeds up the design process.

Figma to Slint Plugin

Select elements in Figma and view the corresponding Slint code.

Copy the code into Slint Live-Preview and collaborate with the development team.

Live-Preview

Complete your UI design through quick iterations using Live-Preview.

Tweak everything, like colors, animations, geometries, or text. and verify the changes instantly.

Live-Preview Data Editor

Change component's properties and global properties in real-time to test interactions and animations without recompiling.

Validate UI/UX on target device.

Responsive

Build a responsive UI from a single design.

Target different screen resolution and sizes with flexible layouts.

Declarative GUI

Improve productivity and code efficiency by eliminating the need to write and maintain hundreds of lines of instructional code. Slint uses a declarative Domain Specific Language (DSL) to describe the user interface elements and compiles them to native code.

Testimonials

"I'm building "Here Now", an open source virtual office-space for helping remote teams feel more connected. Slint has made it easier to prototype and share ideas directly in Slint markup including breakpoints, animations, and layout logic much more easily than the equivalent in CSS/HTML/JS."

Cole Lawrence

"Slint is replacing our HMI written in Qt QML and has reduced or eliminated bugs, improved performance, and made it much easier to rapidly design the UI."
