Joy-Con Toolkit is a versatile utility for Windows that provides Nintendo Switch enthusiasts with deep control over their Joy-Con and Pro Controllers.

Beyond aesthetics, the tool offers essential technical functions such as viewing real-time battery levels, checking firmware versions, and retrieving unique hardware identifiers like serial numbers.
In addition to customization, the toolkit serves as a vital maintenance resource for power users and modders.
