If you're on OS X there is always Amethyst [1], previous discussion [2]. I use it everyday.

On a tangent: For automation and window management (via Lua), check out the awesome Hammerspoon [3].

The maintainer of Amethyst is an awesome person too. Amethyst is honestly the single thing that makes OS X tolerable for me.

That said, it's nowhere near as good as a real tiling WM. There are still the technical limitations of the OS X system to fight.
