This is pre-alpha software.

V UI is a cross-platform UI toolkit written in the V programming language for Windows, macOS, Linux, Android, and soon iOS and the web (JS/WASM). V UI uses native widgets on Windows and macOS, on all other platforms the widgets are drawn by V UI. Right now only the non-native widgets are available.

This is a very early version of the library, lots of features are missing, lots of things will change.

The API is declarative, and there will be hot reloading, similar to SwiftUI and Flutter.

On Linux, V UI will be a full-featured lightweight alternative to GTK and Qt.

0.1 roadmap

Discord: #v-ui channel

Documentation will be available soon. In the meantime use the examples as the documentation. The framework is very simple and straightforward.


Binaries built with V UI will have no dependencies.

To develop V UI apps, you need to install V . This takes a couple of seconds.

On some Linux distros you also need a few development dependencies:

  • Arch: sudo pacman -S libxi libxcursor mesa
  • Debian/Ubuntu: sudo apt install libxi-dev libxcursor-dev mesa-common-dev
  • Fedora: sudo dnf install libXi-devel libXcursor-devel mesa-libGL-devel

On ChromeOS Linux/Crostini, install the Debian dependencies listed above followed by this:
