ImTui is a C++ library for building immediate mode text-based user interfaces that run directly in the terminal. It brings the power of Dear ImGui to terminal applications, allowing developers to create rich, interactive text-based interfaces with minimal code.

Key Features:

256 ANSI color support for vibrant terminal UIs
Mouse and keyboard input handling for interactive applications
Immediate mode rendering for responsive, efficient UI updates
Full Dear ImGui compatibility - use the entire ImGui widget set in your terminal
Cross-platform support including Linux, Mac, Windows (via MSYS2), and browser (via Emscripten)
Minimal dependencies - only requires libncurses

Perfect for:

Terminal dashboards and monitoring tools
Text-based configuration editors
Interactive CLI applications
System administration utilities
Real-time data visualization in the terminal

ImTui powers real-world applications like text-based Slack and Hacker News clients, configuration editors, and terminal dashboards. The library includes multiple examples and can be compiled for both native terminals and web browsers using Emscripten for demonstrations. Building is straightforward with CMake, and the immediate mode architecture ensures your UI stays responsive even with frequent updates.
