Advanced keyboard and mouse remapping with per-key control
Simple, precise, and built for productivity & games.
KeyCore is a powerful keyboard and mouse remapper that goes beyond basic functionality. It lets you customize classic Windows settings such as repeat delay, repeat rate, and key cooldowns—on a per-key basis.
Optimize your APM and unit management with custom repeat rates and ergonomic layouts.
Perfect your spell casting and item usage with per-key cooldowns and precise remapping.
I built KeyCore because I learned that some mouse and keyboard drivers offered the possibility of per-key repeat rate, and I just wanted to make it more generally available as well as explore the possibilities in different games.
It’s not a corporate product—it’s a passion project built for precision and performance. When you buy KeyCore, you’re supporting independent development and getting a tool built by a gamer, for gamers.
Is it safe? Yes — KeyCore runs locally. We recommend reading the EULA and checking rules for online platforms. Follow tournament or platform rules.
