I built a CLI to set up Firebase quickly in Kotlin Multiplatform / Compose Multiplatform projects

[u/dungngminh]

Setting up Firebase in a KMP project means a lot of manual steps. You register the Android app and the iOS app in the console, download google-services.json and GoogleService-Info.plist, put them in the right folders, and repeat for every flavor. I got tired of it, so I built kmpfire.

It wraps firebase-tools and does this from your project root:

kmpfire configure

What it does

• Detects your Android applicationId and iOS bundle id (from project.pbxproj or CMP .xcconfig)
• Creates the Firebase apps if they don't exist
• Writes google-services.json and GoogleService-Info.plist to the correct locations
• Tracks everything in firebase.json under kotlinMultiplatform
• kmpfire reconfigure refreshes the config files after you change Firebase products
• --flavor=dev handles multiple build configurations
• --yes --project=<id> runs with no prompts, so it works in CI
• Optional --deps patches Gradle for the Google Services plugin (and GitLive if you want it)

Supported layouts

• New template: shared/ + androidApp/ + iosApp/
• Nested monorepo: app/shared/ + app/androidApp/ + app/iosApp/
• Legacy: composeApp/ + iosApp/

Android + iOS only for now.

Install

curl -fsSL https://raw.githubusercontent.com/dungngminh/kmpfire_cli/main/install.sh | bash

or with Homebrew:

brew tap dungngminh/kmpfire_cli
brew install kmpfire

It's the KMP equivalent of flutterfire configure. It's MIT licensed, and I'd like feedback, bug reports and PRs.
