Fyne is a free and open-source cross-platform widget toolkit for creating graphical user interfaces (GUIs) across desktop and mobile platforms. It is designed to enable developers to build applications that run on multiple desktop and mobile platforms/versions from a single code base. Fyne uses OpenGL to provide cross-platform graphics. It is inspired by the principles of Material Design to create applications that look and behave consistently across all platforms. It is licensed under the terms of the 3-clause BSD License, supporting the creation of free and proprietary applications. In December 2019 Fyne became the most popular GUI toolkit for Go, by GitHub star count and in early February 2020 it was trending as #1 project in GitHub trending ranks.
