Ranked in these QuestionsQuestion Ranking
Pro Free and open source
Spectacle is licensed under MIT with source code available on GitHub.
All windows in Spectacle can be controlled with keyboard shortcuts, so no mouse is needed. This makes for a fast way to control windows.
Pro Low footprint
Spectacle only uses up 18-19 MB of RAM, which means there is not much overhead by using this app.
Pro Simple hotkeys
Spectacle offers easy-to-remember preset hotkeys.
Pro Multi-monitor support
Pro Great UX
Spectacle is easy to use and configure. It's plug and play.
Pro FinderMinder support
FinderMinder allows you to specify where (position) and what size you want newly opened Finder windows to appear. The default Finder behavior is to remember the last position and size for every window, but this can be frustrating if you already know where you want every window to appear (for example, centered at 800x600). FinderMinder must be running for window reposition and resize to take place.
FinderMinder must continue running in the background for window reposition and resize to take place, so click the "Hide" button to dismiss the preferences and keep FinderMinder running. Simply re-launch FinderMinder to access the preferences again or to quit the app.
Pro Cheap and has a free trial
The app costs just $3 and offers a free trial for testing it out before buying.
Pro Has almost all the features needed in a window manager app
I've tried almost every app on this list. I thought it was amazing how many there were out there by the time I finally stopped experimenting and searching for the one I liked most. I chose Optimal Layout mostly because it was sufficiently extendable and felt lighter to use than the others. There were lighter ones, but those were very limited in their features and customizability.
Pro It's free! Which is fair as it manages only windows for Finder.
The price is right! It comes from a great source of developers who already have window manager apps on this page's list. I am not sure what they plan to do with this app in the future, whether to keep it light and by itself and work in conjunction with their other window managers, or add this feature solely to one of their other fully featured window manager apps.
Con Impossible to add new functions
While keyboard shortcuts can be changed for the available actions, there is no way to add custom actions which in turn limits the functionality of the app.
Con Not Maintained
The software is free, but no longer seems to be maintained.
Con Breaks on macOS High Sierra / Chrome or Firefox
Doesn't support side by side windows.
Con Doesn't work with any Adobe products
There are some apps like Adobe Reader that do not work with Spectacle. Basically, any app with a heavily customized UI that breaks OS X accessibility will not work correctly under Spectacle.
Con Limited window sizing capabilities
You can use 1/2 of the screen vertically and horizontally (divide into 4 parts). You can also use the screen in thirds too, but only the left and right third: you can't use the 1/3 in the center. There is no way to do a more granular distribution.
