The Problem
Every Compose developer is stuck between two bad options: fight Material3's opinions on every screen, or build everything from scratch. There's been nothing in between.
RikkaUI is the third option. 40+ production-ready components built on compose.foundation only — no Material3 anywhere. Copy the source into your project, own it fully, and customize without limits.
The same philosophy shadcn/ui brought to the web, now for Compose Multiplatform.
Quick Start
Option 1 — Gradle dependency (fastest, great for prototyping)
// build.gradle.kts
dependencies {
implementation("dev.rikkaui:foundation:0.3.0") // theme system
implementation("dev.rikkaui:components:0.3.0") // all components
}
RikkaTheme {
Button(text = "Get Started", onClick = { })
}
Works out of the box for native Android projects — no KMP setup needed. For Compose Multiplatform, add to your
commonMainsource set.
Option 2 — CLI (copy-paste with a command, full ownership)
curl -fsSL https://rikkaui.dev/install.sh | bash
Then in your project:
rikkaui init # set up your project for RikkaUI
rikkaui add button card input # copy components into your source
rikkaui list # browse all available components
Components are copied directly into your source. You own the code — no version conflicts, no breaking updates, no opinions you can't change.
Only foundation is required as a Gradle dependency — it provides the theme system your copied components build on.
Theme System
One line changes your entire app's personality:
// Style presets — shapes, spacing, motion, type scale
RikkaTheme(preset = RikkaStylePreset.Default) { } // Balanced
RikkaTheme(preset = RikkaStylePreset.Nova) { } // Sharp & dense
RikkaTheme(preset = RikkaStylePreset.Vega) { } // Rounded & bouncy
RikkaTheme(preset = RikkaStylePreset.Aurora) { } // Spacious & large
RikkaTheme(preset = RikkaStylePreset.Nebula) { } // Square & tight
// Color palettes
RikkaTheme(palette = RikkaPalette.Zinc) { } // Pure & clean
RikkaTheme(palette = RikkaPalette.Slate) { } // Cool blue tint
RikkaTheme(palette = RikkaPalette.Stone) { } // Warm earth tint
// Or just the defaults
RikkaTheme { }
5 palettes × 7 accent colors × light/dark mode. Every token is overridable.
Components
40+ components, all built on compose.foundation only.
