bubbletea-rs

A Rust reimagining of the delightful Bubble Tea TUI framework — inspired by, and paying homage to, the original Go project from Charmbracelet.

Build delightful terminal user interfaces with the Model-View-Update pattern, async commands, and rich styling capabilities.

Status: Active development. Core APIs are stabilizing, but some interfaces may still evolve.

Examples

I tried to match all the examples from the bubbletea repository in rust. You can view the examples here:

The Ecosystem

The Rust Bubble Tea ecosystem consists of three complementary crates:

Crate	Repository	Purpose
bubbletea-rs	bubbletea-rs	Core MVU framework with async runtime
bubbletea-widgets	bubbles-rs	Pre-built UI components (spinners, inputs, tables, etc.)
lipgloss-extras	lipgloss-rs	Styling framework with colors, layouts, and rich text

Crates.io:

All crates are published to crates.io:

Quick Start

Add these dependencies to your Cargo.toml:

[dependencies]
bubbletea-rs = "0.0.9"
bubbletea-widgets = "0.1.12"
lipgloss-extras = { version = "0.1.1", features = ["full"] }

About

Bubble Tea (Go) popularized a functional, message-passing architecture for building terminal applications. This project explores those ideas in Rust: an ergonomic, async-friendly take on the Model–Update–View pattern, with a focus on correctness, performance, and great developer experience.

Core Features

Model-View-Update Architecture: Clean separation of state, rendering, and updates
Async-First Design: Built on Tokio with async commands and non-blocking operations
Rich Styling: Full color support, gradients, borders, and layouts via lipgloss-extras
Pre-built Components: 13+ widgets including spinners, inputs, tables, progress bars
Command System: Timers, HTTP requests, batch operations, and custom async commands
Terminal Controls: Mouse support, alternate screen, window sizing, focus management
Type Safety: Leverages Rust’s type system for reliable, memory-safe TUIs
