6 free tools here have a page comparing themselves with a flat price per square foot
Each page below is written by the author of the free tool, cites a flat price per square foot's own public documentation, and says three things: what a flat price per square foot does, what the free tool does, and when a flat price per square foot is the right answer. None of them is affiliated with, endorsed by, or reviewed by a flat price per square foot, and none is a statement about its quality — only about what each tool does and does not do.
