Fcitx 5 is a generic input method framework, the next generation of Fcitx, released under LGPL-2.1+. It provides a slim core with addon support for typing in many languages, primarily targeting Linux and BSD systems with X11 and Wayland.

Use cases

type Chinese, Japanese, or Korean on Linux
switch keyboard layouts on Wayland
set up an input method framework for multiple languages
write a custom input method addon
use an input method in TTY via fbterm or tmux

When to choose

you need a customizable input method framework on Linux/BSD
you want X11 and Wayland support
you need to develop your own input method engines or addons

When to avoid

you need input method support on macOS or Android (use the separate fcitx5-macos or fcitx5-android projects)
you only need a simple keyboard layout switcher without language engines
you want a fully packaged turnkey solution without installing separate engines
