ImTui is an immediate mode text-based user interface (TUI) C++ library that ports the Dear ImGui API to the terminal via ncurses, supporting 256 ANSI colors and mouse/keyboard input. It also compiles to WebAssembly with Emscripten for in-browser demos.

Use cases

• build a terminal UI in C++ with an immediate mode API
• port an existing Dear ImGui app to the terminal
• create a text-based client for a web service like Slack or Hacker News
• render interactive widgets with 256 colors in a TUI
• run a TUI app in the browser via Emscripten
• handle mouse and keyboard input in a terminal application

When to choose

• you want Dear ImGui's API and widget set inside a terminal
• you're writing a C++ interactive TUI and prefer immediate mode over ncurses directly
• you need the same UI code to run in terminal and browser (WASM)

When to avoid

• you need a rich graphical (non-text) GUI
• you prefer retained-mode TUI frameworks or are not using C++
• you need advanced terminal features beyond ANSI colors and basic mouse/keyboard support
