Modular utilities for clipboard operations, Compose toast/snackbar, and in‑app update checks — zero‑config auto-initialization, clipboard observer with foreground detection, customizable toast durations, positions, styles.
A collection of production-ready Kotlin Multiplatform libraries — one dependency per feature, works out of the box on every platform.
📖 Full usage docs: Docs site · Wiki · 🚀 Releases · 📦 Maven Central
The Docs site ships an API reference for every module via Dokka HTML bundled inside each Maven Central
-javadoc.jarartifact — IntelliJ / Android Studio surface it automatically in hover popups.
All modules ship together at the unified kmptoolkit.version. Click a module to open its Wiki page (install + usage + per-platform behaviour).
Each module is completely independent — add only what your project needs.
All modules ship together at the unified kmptoolkit version. Declare it once in your version catalog, then add only the libraries you need:
Then reference any library from commonMain via the standard implementation(libs.cmp.<name>) pattern.
💡 Replace
LATESTwith the version shown in the Maven Central badge at the top of this README — single source of truth, single line to bump when a new release ships.
The toolkit targets every platform Kotlin Multiplatform supports. Per-module coverage varies — see each module's Wiki page for the authoritative matrix. Quick reference:
📊 Full per-module × per-target matrix: Wiki › Platform Matrix · docs/inter-app-comms/CAPABILITY_MATRIX.md
Three modules ship together as the inter-app communication suite — all share the same Compose-MP adapter pattern (core + -compose adapter):
Architecture docs: docs/inter-app-comms/CAPABILITY_MATRIX.md · ADR-09 (platform-impl-exits)
sample-toolkit is the unified catalog app — every published cmp-* module wired in one Compose Multiplatform project. Pick a module from the catalog UI to launch its dedicated showcase. Same app, every platform:
# Desktop (JVM)
./gradlew :samples:sample-toolkit:composeApp:run
# Android
./gradlew :samples:sample-toolkit:androidApp:installDebug
# Web (browser — JS + wasmJs)
./gradlew :samples:sample-toolkit:composeApp:jsBrowserDevelopmentRun
./gradlew :samples:sample-toolkit:composeApp:wasmJsBrowserDevelopmentRun
# iOS — open samples/sample-toolkit/iosApp in Xcode
Per-module standalone samples (one per library) live alongside sample-toolkit under samples/ — useful if you want to study a single module in isolation.
First-run note (web targets):
jsBrowserDevelopmentRun/wasmJsBrowserDevelopmentRundownloads ~50MB of Skiko WASM assets on a cold cache. Subsequent runs are fast. If you hitOutOfMemoryError: GC overhead limit exceeded, ensureorg.gradle.jvmargs=-Xmx4096Mingradle.properties(the repo default).
New module template lives at cmp-library/ — copy + rename + add to settings.gradle.kts + ship a sample under samples/. Full walkthrough: Wiki › Adding New Features · CONTRIBUTING.md.
