KeybindCompanion is a desktop application for managing and referencing game keybinds across multiple titles. It provides a centralized library where players can store, organize, and back up their control configurations outside of the game itself, with a split-pane Profile Studio for comparing default and custom bindings side-by-side. The app features a community-driven Profile Hub for sharing configurations, offline-first design with local storage, multi-device support (keyboard, mouse, gamepad, joysticks, wheels), and is built to be anti-cheat safe by never modifying game files. Built with Electron, React, and TypeScript, distributed via itch.io as a one-time purchase with lifetime updates for Windows 10/11.
