Ratatui is a widely trusted and highly popular open-source Rust library used for building interactive terminal user interfaces. It is a legitimate, free, and community-maintained project that offers high performance for developers building CLI tools, dashboards, and monitoring utilities. It is an excellent choice for Rust developers looking for flexibility and power in TUI design, though users should be prepared to handle their own input and event logic.
Video reviews
Pros
- Highly performant and flexible for complex, multi-window terminal applications.
- Active development cycle and community support.
- Cross-platform support (Linux, macOS, Windows).
- Well-documented with tutorials, templates, and example projects.
Cons
- Requires manual implementation of input handling and event systems, as it focuses on rendering.
- Immediate-mode rendering can introduce overhead for highly dynamic content, though this is rarely a bottleneck.

Better options
Why switch: An established alternative for building text-based user interfaces in Rust, using an ncurses-based approach.
A declarative TUI library for Rust, which offers a different architectural approach compared to Ratatui's immediate-mode rendering.
