Ratatui is a Rust library for cooking up terminal user interfaces (TUIs). It provides a simple and flexible way to create text-based user interfaces in the terminal, which can be used for command-line applications, dashboards, and other interactive console programs.
This is free and open source software.
Key Features
- Fast and lightweight – sub-millisecond rendering with zero-cost abstractions and immediate-mode rendering. Build responsive dashboards and complex terminal applications that feel instant, even with many widgets on screen. No runtime overhead, just pure Rust performance.
- Rich widgets – craft professional TUIs: charts, sparklines, tables, gauges, scrollable lists, progress bars, and more. Mix and match widgets to create interactive dashboards, monitoring tools, games and more.
- Dynamic layouts – build complex nested layouts with horizontal and vertical splits, automatically sized containers, and percentage-based constraints.
- Rust reliability – memory-safe, thread-safe, and type-safe by design. No C dependencies, no runtime exceptions, no undefined behavior
