Fastlane
An open-source tool suite that automates the tedious processes of building and releasing iOS and Android apps, such as generating screenshots and managing certificates.
What it is
Fastlane replaces manual app store deployment processes with automated Ruby scripts. It interacts directly with the Apple App Store Connect API and Google Play Console to automatically sign binaries, generate localized marketing screenshots, update metadata, and push beta builds without human intervention.
When you would use it
You use Fastlane when you want to remove the manual, error-prone steps of packaging and submitting a mobile app to Apple and Google for release.
Common operations
- Automating TestFlight beta distribution via a single terminal command.
- Automatically generating and uploading App Store screenshots across all device sizes.
