Mosaic is a Kotlin library for building terminal (console) UIs using the Jetpack Compose compiler and runtime, inspired by Ink. It lets developers write declarative, state-driven text-based interfaces with composable functions rendered to the terminal.

Use cases

• build a terminal UI in Kotlin with Compose
• create animated CLI progress displays with live-updating state
• render test-runner style output like Jest in the terminal
• build TUI dashboards and monitoring views in Kotlin
• write declarative console apps with reactive state

When to choose

• you want a declarative, Compose-based approach to terminal UIs in Kotlin
• you're already familiar with Jetpack Compose and want the same model on the JVM CLI
• you need dynamic, state-driven console output rather than static prints

When to avoid

• you need a full-featured TUI with mouse support, panels, or complex widgets
• you're not using Kotlin or unwilling to apply the Compose compiler plugin
• you need a stable, long-term-supported API since the project is explicitly experimental
