Pros

Free and open-source under the MIT License, usable for personal or commercial projects
Over 33.5 million downloads on crates.io, indicating wide adoption and trust in the Rust ecosystem
4,400+ crates built with it, demonstrating broad real-world utility
21,100+ GitHub stars reflecting strong community endorsement
Sub-millisecond rendering with immediate-mode rendering for highly responsive TUIs
Zero external C dependencies, relying entirely on pure Rust for memory and thread safety
Supports no_std for embedded targets beyond standard terminal environments
Rich built-in widget library including charts, tables, gauges, sparklines, scrollable lists, and progress bars
Constraint-based responsive layouts that automatically adapt to any terminal size
Active maintenance with a current release (v0.30.2) and ongoing development
Multiple official community channels including Discord, Matrix, GitHub, and a Discourse forum
Comprehensive documentation hosted on docs.rs and the official ratatui.rs site
Large ecosystem of example apps and video tutorials easing the learning process
Backed by industry adoption, with notable apps like csvlens, binsider, and oxker built on it

Cons

Low-level library that requires a separate crate (e.g., Crossterm) for input and event handling
Steeper learning curve for beginners compared to higher-level alternatives like Cursive
Rust-only; not usable from other programming languages
Immediate-mode rendering requires the developer to manually trigger and manage redraws each frame
No built-in application state management or component lifecycle system
Terminal-only output; not suitable for GUI or web interfaces without additional tooling
Forked from the now-unmaintained tui-rs, so some older tutorials and code examples target the predecessor and may not be directly compatible
