A Go-based GUI framework using LCL and CEF for building cross-platform desktop applications with web technologies.
Energy is a Go-based GUI framework for developing cross-platform desktop applications for Windows, macOS, and Linux. It combines the native widget library LCL and the Chromium Embedded Framework (CEF) to enable developers to build applications using both native system components and modern web technologies like HTML, CSS, and JavaScript.
Go developers who need to create desktop applications that run on Windows, macOS, and Linux, especially those who want to leverage web technologies for the UI while using Go for system-level operations.
Developers choose Energy for its unique hybrid approach, allowing them to build lightweight native applications with LCL or feature-rich applications with CEF, all from a single Go codebase with fast compilation and minimal setup.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Allows building for Windows, macOS, and Linux from a single Go codebase, with explicit support for ARM architectures, as shown in the system support table.
Supports HTML, CSS, JavaScript, and frameworks like Vue, React, and Angular, enabling modern UI development while Go handles system-level logic, per the philosophy.
Event-driven communication based on IPC facilitates efficient interaction between Go and web components, as highlighted in the characteristics for seamless integration.
Resources can be loaded locally, from embedded files, or via HTTP services, providing versatility in deployment, as noted in the feature list.
Requires setting up CEF and LCL via the energy CLI, adding complexity and potential installation hurdles compared to lighter Go GUI alternatives.
Including CEF significantly increases application size, which can be prohibitive for distribution-sensitive projects, a common trade-off with embedded browsers.
Combining LCL's native widgets with CEF's web components may lead to visual inconsistencies across platforms, as web UIs might not match system look-and-feel.
