fastlane is a mobile DevOps framework and release automation tool designed to coordinate the building, signing, and distribution of iOS and Android applications. It functions as a build orchestrator and distribution manager that automates the delivery of mobile apps to app stores and testing environments.
The project distinguishes itself through a plugin-based extension model that allows for custom action sets and a specialized system for managing developer resources. It automates the synchronization of code signing certificates and provisioning profiles and handles secure account authentication via system keychains.
The framework covers a broad range of capabilities, including the orchestration of continuous integration and delivery pipelines, automated test execution for iOS and macOS, and the management of store metadata and localized screenshots. It also provides tools for beta distribution management and compliance validation against store review rules.
