  • Energy is a GUI framework developed in Go, based on LCL and CEF(Chromium Embedded Framework), which is used to develop cross-platform desktop applications for Windows, MacOS, and Linux.
  • LCL alone can create lightweight native applications, or can be combined with CEF to create more feature-complete applications.
  • Construct cross-platform desktop applications that support Windows, Linux, and MacOS using Go and web technologies (HTML + CSS + JavaScript).


  • Rich CEF API and LCL system native widgets
  • Development environment is simple and the compilation speed is fast. Only need Go and Energy.
  • Cross-Platform: You can package your code as Windows, domestic UOS, Deepin, Kylin, MacOS and Linux
  • Responsibilities
    • Go: Go is responsible for creating Windows, configuring CEF and implementing functions, creating various UI components, calling the low level of the system and some functions that JS cannot handle, such as: file flow, security encryption, high-performance processing, etc.
    • Web: HTML + CSS + JavaScript is responsible for the function of the client interface, you can make any interface you want.
  • Front-end technology: Support mainstream frameworks, such as Vue, React, Angular or pure HTML+CSS+JS.
  • Event driven: High performance event driven communication based on IPC allowing intercommunication between Go and Web.
  • Resource loading: You can either read local resources or resources built into execution files either with or without HTTP services.

Built-in dependency&integration

  • LCL
  • CEF-CEF4Delphi

Basic needs

  • Golang >= 1.18
  • Energy (CEF, liblcl)

Environmental installation

Automatic installation development environment using the energy command-line tool

Guide to Start - Link

Quick Start

  • Using energy command line tools to install the complete development environment automatically.

Run a simple application by three steps

  1. Install development environment: energy install .
  2. Initiate an Application: energy init .
  3. Run the Application: go run main.go

sample code


package main

import (

func main() {
	//Global initialization
	cef.GlobalInit(nil, nil)
	//Create an application
	app := cef.NewApplication()
	//Specify a URL address or local HTML file directory
	cef.BrowserWindow.Config.Url = ""
	//Run Application


  1. Build:energy build .
  2. Package:energy package .
  3. Package Type:
    • windows: Using nsis create exe installation package
    • linux: Using dpkg create deb installation package
    • macos: Generate
