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

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:
# gradle/libs.versions.toml
[versions]
kmptoolkit = "LATEST" # see Maven Central badge in the Modules table above
[libraries]
cmp-clipboard = { module = "io.github.mobilebytelabs:cmp-clipboard", version.ref = "kmptoolkit" }
cmp-bubble = { module = "io.github.mobilebytelabs:cmp-bubble", version.ref = "kmptoolkit" }
cmp-toast = { module = "io.github.mobilebytelabs:cmp-toast", version.ref = "kmptoolkit" }
cmp-open-url = { module = "io.github.mobilebytelabs:cmp-open-url", version.ref = "kmptoolkit" }
cmp-deep-link = { module = "io.github.mobilebytelabs:cmp-deep-link", version.ref = "kmptoolkit" }
cmp-in-app-update = { module = "io.github.mobilebytelabs:cmp-in-app-update", version.ref = "kmptoolkit" }
cmp-remote-config = { module = "io.github.mobilebytelabs:cmp-remote-config", version.ref = "kmptoolkit" }
cmp-product-tickets = { module = "io.github.mobilebytelabs:cmp-product-tickets", version.ref = "kmptoolkit" }
cmp-network-monitor = { module = "io.github.mobilebytelabs:cmp-network-monitor", version.ref = "kmptoolkit" }
cmp-pdf-generator = { module = "io.github.mobilebytelabs:cmp-pdf-generator", version.ref = "kmptoolkit" }
cmp-firebase-analytics = { module = "io.github.mobilebytelabs:cmp-firebase-analytics", version.ref = "kmptoolkit" }
cmp-share = { module = "io.github.mobilebytelabs:cmp-share", version.ref = "kmptoolkit" }
cmp-intent-launcher = { module = "io.github.mobilebytelabs:cmp-intent-launcher", version.ref = "kmptoolkit" }
cmp-app-intents = { module = "io.github.mobilebytelabs:cmp-app-intents", version.ref = "kmptoolkit" }
# Compose adapter modules (optional)
cmp-share-compose = { module = "io.github.mobilebytelabs:cmp-share-compose", version.ref = "kmptoolkit" }
cmp-intent-launcher-compose = { module = "io.github.mobilebytelabs:cmp-intent-launcher-compose", version.ref = "kmptoolkit" }
cmp-app-intents-compose = { module = "io.github.mobilebytelabs:cmp-app-intents-compose", version.ref = "kmptoolkit" }
cmp-network-monitor-compose = { module = "io.github.mobilebytelabs:cmp-network-monitor-compose", version.ref = "kmptoolkit" }Then reference any library from commonMain via the standard implementation(libs.cmp.<name>) pattern.

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:

Three modules ship together as the inter-app communication suite — all share the same Compose-MP adapter pattern (core + -compose adapter):
- cmp-share + cmp-share-compose — share sheets via OS-native dispatch
- cmp-intent-launcher + cmp-intent-launcher-compose — typed
Intentbuilder + lifecycle-freeSystemIntents(settings + save dialog) + Composable launchers - cmp-app-intents + cmp-app-intents-compose — declarative App Intents DSL (SiriKit + Assistant BIIs)

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 XcodePer-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.
