Since you're a web developer, I wonder if something like Electron or one if its variants would be good (but maybe overkill).

I've used HTA HTML Applications[0] to make small utilities. They're also web-based but apparently only compatible with Internet Explorer and I don't know if there's a future in it, though Microsoft tends to keep old technologies around for backwards compatibility. But if you are already know how to support Internet Explorer today, it might not be much of a stretch. There might be other products similar to this.
