Lorca
Build cross-platform modern desktop apps in Go + HTML5
...Go functions can be exposed to JavaScript, while Go code can evaluate scripts and control the web interface. Communication works asynchronously through promises and goroutines, allowing long-running backend tasks without blocking the UI. Applications can load content from a local server or a data URL and may open multiple windows. Lorca is written in pure Go without cgo and typically produces small application packages. It also supports headless testing, cross-platform packaging, custom branding, and native integrations through external libraries.
