Lanterna is a pure-Java library for building text-based semi-graphical user interfaces (TUIs) in terminal environments, similar to the C curses library. It provides three layers: a low-level terminal control API, a screen buffer for bitmap-like text rendering, and a full GUI toolkit with windows and components.

Use cases

• build a text-based GUI in Java
• create a curses-like terminal interface in pure Java
• write a TUI app that runs on headless servers
• add windows and buttons to a console application
• render full-screen text UIs over SSH or xterm terminals
• develop terminal UIs from an IDE without ANSI support

When to choose

• you need a text-mode GUI toolkit in Java with no native dependencies
• your app must run on headless servers or over SSH in xterm-compatible terminals
• you want a Swing-based terminal emulator fallback when developing in a graphical IDE
• you need layered control from raw terminal I/O up to a full windowing toolkit

When to avoid

• you need a graphical (pixel-based) desktop GUI rather than a text interface
• you are building a web or mobile application
• you need a TUI toolkit for a language other than Java on the JVM
• you require advanced non-modal window management or GPU-accelerated rendering
