## What it is
fastlane is an open-source Ruby-based CLI tool that automates building, code signing, screenshot generation, and releasing of iOS, macOS, and Android apps. Developers define release workflows as 'lanes' in a Fastfile, integrating with App Store Connect, Google Play, TestFlight, and 400+ other services.

## Use cases
- automate iOS and Android app store releases
- generate localized App Store and Google Play screenshots
- distribute beta builds to TestFlight or Google Play
- manage iOS code signing certificates and provisioning profiles
- upload app metadata and screenshots to the App Store
- run mobile release pipelines from CI
- increment build numbers and version apps automatically

## When to choose
- you release iOS or Android apps frequently and want to automate builds, signing, and uploads
- you need consistent, localized screenshots across many devices and languages
- you want a single tool that works with App Store Connect, Google Play, and major beta services
- you want repeatable release lanes that run locally or on any CI server

## When to avoid
- you build web apps or non-mobile software
- you only need simple one-off builds without release automation
- you are not comfortable with Ruby-based configuration and tooling
- you need fully managed cloud release infrastructure rather than a local CLI
