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

      It adjusts colours the way I expected it to. There is a simple and efficient gui applet (redshift-gtk) available, and it supports interesting commandline options

      Has minimal performance impact and can be configured to have no impact at all (at the cost of smoothness). Best choice if you are a gamer.

      + Free & open source + Adds the feature of setting your own sunset and sunrise times, which the f.lux developer(s) did not want to add + Access to the keyboard/mouse logging hook MSCTF.dll can be declined without affecting functionality except for the ability to configure quick-keys - Occasionally crashes when denied a permission by comodo HIPS, but nothing so regular that it gets in the way of use.

      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).
