There are many diet drinks on the market that do not contain aspartame, including a specially labeled version of Diet Coke, Diet Rite, Hansen's Natural soda, Pepsi One and Zevia. Most of these products use Splenda, a sugar-derived artificial sweetener, or stevia, a natural sweetener that is up to 300 times sweeter than cane sugar.
