ratatui

A lightweight Rust crate for cooking up terminal user interfaces with immediate-render efficiency.

Ratatui is the community-driven successor to tui-rs, providing a robust framework for building rich TUIs in Rust. It operates on an immediate-mode rendering model: you define the UI layout (using Rects and Constraints) and draw widgets (like Sparklines, Gauges, or Tables) every frame. This approach eliminates complex state synchronization between the backend and the display. With support for crossterm, termion, and termwiz backends, Ratatui powers high-performance tools like bottom and gitui, ensuring your terminal applications remain responsive under heavy data loads.
