Fyne is a free and open-source cross-platform widget toolkit for creating graphical user interfaces (GUIs). It allows application software to run on multiple desktop, mobile operating systems, Web browsers (via WebAssembly) and embedded devices (embedded Linux) from a single code base. Fyne is inspired by the principles of Material Design to create applications that look and behave consistently. It uses OpenGL to provide cross-platform GUIs.

Fyne 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.
