This is open source, while f.lux wants you to download a binary and run it constantly on your system.

So happy I can set my own times. In the winter the sunsets happened way to earlier in Flux, then I'd turn it off and forget to turn it back on.

Very minimalistic and lightweight. Doesn't affect games (i.e. microstuttering) the way f.lux does (if you set it to Paused mode).
