Key Mapper GUI Keyboard

The official companion keyboard for Key Mapper.

Features & Capabilities

Key Mapper GUI Keyboard is the official companion keyboard for the Key Mapper Chrome extension. Designed as a 100% free and open-source software (FOSS) tool, it offers a user-friendly on-screen keyboard interface built as a fork of OpenBoard, a keyboard based on the Android Open Source Project (AOSP).

Unlike the built-in Basic Input Method within Key Mapper which lacks a graphical user interface (GUI), this extension provides convenient on-screen buttons for easier input management. It is ideal for users seeking a reliable and customizable keyboard experience integrated with Key Mapper's functionality, enabling smooth key mapping and input customization.

User Reviews

Reviews show broad satisfaction with Key Mapper GUI Keyboard, with praise for autocorrection/text prediction and external keyboard support. However, recurring concerns include compatibility issues on Android 15 and some devices, a lack of swipe typing, and several feature requests (integrated undo, arrow keys, floating typing, and better gamepad detection). Overall, the app is well-liked, but reliability on certain devices and missing features are common themes.
Pros
  • Strong overall positive reception; many reviewers call it the best/good/excellent app.
  • Autocorrection and text prediction are standout features for a FOSS keyboard.
  • Supports external keyboards (e.g., Bluetooth keyboards) and general keyboard functionality.
  • Back button customization is cited as a useful capability.
Cons
  • Compatibility issues on Android 15 and on some devices (e.g., Vivo) that prevent opening or use.
  • Lack of swipe typing reported as a usability gap.
  • Multiple feature requests indicate gaps: integrated undo button and arrow keys, floating typing, and improved gamepad detection.
  • Layout/rotation problems that can make typing difficult when the screen is rotated, such as oversized keys.
