ratatui-org/ratatui
A Rust crate for building terminal user interfaces (TUIs) with a simple and flexible API.
What is ratatui-org/ratatui?
Ratatui is a Rust crate for creating text-based user interfaces (TUIs) in the terminal. It provides a robust framework for rendering widgets and handling user input, enabling developers to build command-line applications, dashboards, and interactive console programs. The library emphasizes simplicity and flexibility, offering a straightforward way to create rich terminal applications without sacrificing performance or control.
Rust developers building terminal-based applications such as command-line tools, system dashboards, or interactive console programs. It is particularly suited for those who need a widget-based, cross-platform solution for rendering complex interfaces in a terminal environment.
Developers choose Ratatui for its widget-based rendering, flexible layout system, and extensible architecture, which allow for precise control and easy customization. Its cross-platform support and active community, including templates and extensive documentation, make it a reliable choice for modern TUI development in Rust.

Use Cases
Best For
- Building command-line applications with interactive, widget-based interfaces.
- Creating system dashboards or monitoring tools that run directly in the terminal.
- Developing interactive console programs that require precise layout control and event handling.
- Extending existing Rust CLI tools with rich, user-friendly TUI components.
- Prototyping or building cross-platform terminal applications that work across different operating systems and terminal emulators.
- Customizing or creating new widgets for specialized terminal UI needs, thanks to its modular and extensible design.
Not Ideal For
- Projects requiring graphical user interfaces or web-based frontends beyond terminal capabilities
- Developers seeking a declarative, markup-based UI framework similar to HTML or React
- Applications that must run in environments without terminal support, such as headless servers or embedded systems without a TTY
- Teams wanting out-of-the-box, pre-assembled TUI applications without custom Rust development
Pros & Cons
Pros
Provides a collection of pre-built widgets like charts, tables, and lists, enabling complex interface composition without reinventing the wheel, as shown in the widget examples.
Works across different terminal emulators and operating systems, ensuring consistent behavior in diverse environments, which is a core feature highlighted in the documentation.
Offers templates via cargo-generate, a dedicated forum, Discord server, and extensive examples, accelerating project startup and troubleshooting.
Designed to be modular with an extensible architecture, making it easy to create custom widgets, as evidenced by the widget trait and examples in the README.
Cons
Requires integration with backends like crossterm for event handling, adding setup complexity and potential compatibility issues across different systems.
Uses an imperative loop for rendering and events, as shown in the quickstart code, which can be less intuitive than declarative approaches and may lead to boilerplate.
While extensible, the core library has fewer pre-styled widgets compared to mature GUI frameworks, often necessitating custom development or reliance on community contributions.
As a fork from tui-rs, there are documented breaking changes, which can cause migration headaches for projects upgrading from older versions, as noted in the Breaking Changes file.
