## What it is
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

## Facets
- artifact type: framework
- maturity: stable
- function: internationalization, gui, plugin-system
- domain: cross-platform, developer-tools
- platform: bsd, cpp
