How to tell them apart
にとどまらず emphasizes that an action or state goes beyond a boundary and continues or extends further, often with a sense of surpassing expectations or a natural stopping point. に限らず simply means not restricted to one category or case, broadening a scope. この薬は髪を防ぐにとどまらず白髪も戻す implies going beyond what it stops at, while 何事に限らず means regardless of the category. Swapping them sounds off because にとどまらず carries a sense of progression beyond a limit, whereas に限らず is about scope.
- にとどまらず Use にとどまらず when something extends beyond a boundary or expected limit rather than stopping there.
- に限らず Use に限らず when you want to say not limited to a particular category or case, broadening the scope.

not confined to; reaching further than
にとどまらず means something extends beyond a certain scope, pairing with だけ or 単に to stress that the first item is not the whole story. It attaches to a noun, or to a phrase ending in である or する, and the sentence adds a further, often broader item. The tone is formal and written.
