Flocon is an advanced debugging and inspection tool built with Kotlin Multiplatform (KMP), designed to work seamlessly across Android and desktop environments.

Inspired from Flipper by Meta, while leveraging modern Kotlin multiplatform architecture for networking, databases, analytics, and UI data visualization.

It allows developers to connect a Kotlin Multiplatform or Android app to their computer and launch a desktop interface that can observe, inspect, and interact with the running app in real time — across shared Kotlin code and platform-specific implementations.

Since 2.0, the SDK is split into one module per feature: add the core and the plugins you need, each with its -no-op version for release builds.

debugImplementation("io.github.openflocon:flocon:LAST_VERSION")
releaseImplementation("io.github.openflocon:flocon-no-op:LAST_VERSION")

// for example, the network inspector with OkHttp
debugImplementation("io.github.openflocon:flocon-network-core:LAST_VERSION")
releaseImplementation("io.github.openflocon:flocon-network-core-no-op:LAST_VERSION")
debugImplementation("io.github.openflocon:flocon-okhttp-interceptor:LAST_VERSION")
releaseImplementation("io.github.openflocon:flocon-okhttp-interceptor-no-op:LAST_VERSION")

in your Application.kt

startFlocon(FloconContext(this)) {
    install(FloconNetwork)
    install(FloconDatabase) { room() }
    install(FloconAnalytics)
}

// then, anywhere in your app
Flocon.analyticsPlugin.log(AnalyticsEvent("button_clicked", "events"))

On desktop use FloconContext(appName, packageName), on iOS FloconContext().
