Choosing between these
Tools in this category overlap more than their marketing suggests. The useful difference is usually not the model behind them but what they let you do around it: how much control you get over the output, how the work is organised once you have it, and whether the free level is enough for what you are doing.
Each page below lists what the tool is good at and what it is not, along with alternatives worth comparing before you commit.
