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

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.
Con No Longer Maintained
Bare Bones, the developers of TextWranger, recently ended maintenance and support for the product. Per the Bare Bones website (https://www.barebones.com/products/textwrangler/): "We have sunsetted TextWrangler, and we encourage anyone interested in TextWrangler to download and use BBEdit instead."
Con Not Compatible with macOS High Sierra (10.13+)
Per the Bare Bones website (https://www.barebones.com/support/new-os.html): "TextWrangler is not compatible with High Sierra. We suggest that you use BBEdit as an alternative . . . ." Since Bare Bones officially sunsetted the product, it will unlikely be compatible with subsequent macOS release versions either.
