FlexInput vs JoyToKey

FlexInput is a Windows application for routing and mapping HID and MIDI inputs to virtual outputs. Its visual signal graph supports drag-and-drop editing, reusable nested sub-patches, and factory presets. Listed controller inputs include XInput, DualShock 4, DualSense, Switch Pro, Joy-Con 2, and third-party SDL3 controllers; it also accepts MIDI. Outputs include virtual XInput and DualShock 4/DualSense controllers, keyboard, and mouse. MIDI mapping offers per-CC output pins and CC Learn, while supported controllers can provide raw gyroscope and accelerometer data. FlexInput can route an AutoMap gamepad bus between two instances over LAN UDP, encrypted PSK UDP, or P2P transport. LAN UDP is unencrypted; PSK uses a shared passphrase and P2P uses a cryptographic keypair. WASAPI loopback audio can be routed to rumble. HidHide can conceal remapped physical devices but requires a separate driver. The app is free and MIT-licensed. It requires Windows 10/11 (x64); installation uses a Windows x64 ZIP, with no installer.

JoyToKey converts game-controller buttons and stick input into keyboard strokes or mouse actions for Windows applications and web games. A joystick button can be assigned a key, key combination, mouse movement, wheel movement, or click. Users can make multiple profiles and have the active profile switch based on the application in focus. An Auto Setting Wizard helps configure basic assignments, while advanced settings let a button rotate among two or three assignment sets based on rotation, press duration, or analog input level. Button Alias can create virtual buttons, combine functions for one input, or trigger an input when two buttons are pressed together. Profiles can be associated with target applications, and command-line arguments can refresh joystick devices or switch profiles. JoyToKey supports Windows 11, 10, 8, 7, and Vista, and is offered as an installer or ZIP archive, with a separate ASCII-only build. The shareware can be evaluated without functional limits. The JoyToKey License Key is listed at $7.50 a month for continued use after the trial period. The download page states that the product has no warranty.
