We built a background daemon as a macOS menu bar app in Go, and the performance was surprisingly bad. The Go bindings for native UI frameworks ended up being massive RAM hogs. When we profiled it, we found that the GC essentially gave up under load, which explained why customers were reporting a simple menu bar app consuming 2.5GB+ of RAM on their Macs. We eventually abandoned the Go approach and switched to Electron. (Not-so) Surprisingly, both the DX and UX improved significantly for our use case. Personally, I’d still prefer Swift/C#/C++ for native desktop work (coming from a Qt C++ background), but given the business constraints at the time, Electron ended up being the most pragmatic choice.
