Ratatui ↗
Rust TUI framework (successor to tui-rs). Immediate-mode rendering with a rich widget set.
Ratatui is the most popular Rust TUI framework, a community fork of tui-rs. It uses immediate-mode rendering — you redraw the entire UI each frame, and the library diffs against the previous frame to minimize terminal output.
Ratatui works best with the Modern TUI baseline — truecolor for its color system, mouse tracking for interactive widgets, and alternate screen for full-screen rendering. It supports multiple backends (crossterm, termion, termwiz) and has a growing ecosystem of third-party widgets.

Ratatui works best with the Modern TUI baseline (68 features). It runs on less capable terminals but degrades gracefully — some features may be unavailable or visually reduced.
