fyne: Build Cross-Platform Apps with Go

Overview

Fyne is a UI toolkit and app API for building graphical applications in Go. It provides an approach to developing desktop and mobile apps from one codebase, with a consistent interface inspired by Material Design.

It is a fit for Go developers who want to add a native-feeling graphical interface to an application and distribute it across platforms. The project includes widgets and app infrastructure, while separate tools support installing and packaging apps.

Key Features

• Build graphical applications using Go.
• Target desktop and mobile devices from a shared codebase.
• Create interfaces with reusable widgets and layout containers.
• Support light and dark themes.
• Run apps in a mobile simulation mode during development.
• Package applications for Android and iOS, including iOS simulator builds.
• Use the Fyne command-line utility to install or prepare applications for release.

Use Cases

• Go developers building a desktop utility who want to use the same language as their other software.
• Small teams creating a mobile and desktop application without maintaining separate UI codebases.
• Developers prototyping a graphical interface with built-in widgets and layouts.
• App authors preparing Go-based applications for installation or distribution on Android, iOS, or desktop systems.

Getting Started

Install the module and add it to your Go project:

go get fyne.io/fyne/v2@latest

Fyne requires Go 1.22 or later, a C compiler, and system development tools. See the README and developer documentation for setup and platform-specific details.

Considerations

• Development requires Go 1.22 or later, a C compiler, and platform development tools.
• Native platform packaging can require additional toolchains and signing setup, particularly for iOS releases.
• The README notes that the first Windows compilation can take up to 10 minutes, depending on hardware.
• Fyne is a UI toolkit rather than a visual app builder, so developers write and maintain the interface in Go.
