fastlane is the easiest way to automate beta deployments and releases for your iOS and Android apps. 🚀 It handles all tedious tasks, like generating screenshots, dealing with code signing, and releasing your application.
You can start by creating a
Fastfile file in your repository, here’s one that defines your beta or App Store release process:
lane :beta do increment_build_number build_app upload_to_testflight end lane :release do capture_screenshots build_app upload_to_app_store # Upload the screenshots and the binary to iTunes slack # Let your team-mates know the new version is live end
You just defined 2 different lanes, one for beta deployment, one for App Store. To release your app in the App Store, all you have to do is
|🚀||Save hours every time you push a new release to the store or beta testing service|
|✨||Integrates with all your existing tools and services (more than 400 integrations)|
|📖||100% open source under the MIT license|
|🎩||Easy setup assistant to get started in a few minutes|
|⚒||Runs on your machine, it's your app and your data|
|👻||Integrates with all major CI systems|
|🖥||Supports iOS, Mac, and Android apps|
|🔧||Extend and customise fastlane to fit your needs, you're not dependent on anyone|
|💭||Never remember any commands any more, just fastlane|
|🚢||Deploy from any computer, including a CI server|
fastlane can be installed multiple ways. The preferred method is with Bundler. fastlane can also be installed directly through with Homebrew (if on macOS). It is possible to use macOS's system Ruby but it's not recommended as it can be hard to manage dependencies and cause conflicts.
Managed Ruby environment + Bundler (macOS/Linux/Windows)
If you use macOS, system Ruby is not recommended. There is a variety of ways to install Ruby without having to modify your system environment. For macOS and Linux, rbenv is one of the most popular ways to manage your Ruby environment.
fastlane supports Ruby versions 2.4 through 2.7. Verify which Ruby version you're using:
$ ruby --version ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-darwin19]
It is recommended that you use Bundler and
Gemfile to define your dependency on fastlane. This will clearly define the fastlane version to be used and its dependencies, and will also speed up fastlane execution.
- Install Bundler by running
gem install bundler
- Create a
./Gemfilein the root directory of your project with the content
source "https://rubygems.org" gem "fastlane"
bundle updateand add both the
./Gemfile.lockto version control
- Every time you run fastlane, use
bundle exec fastlane [lane]
- On your CI, add
bundle installas your first build step
- To update fastlane, just run
bundle update fastlane
This way you don't have to install Ruby separately and instead homebrew installs the most adequate Ruby version for fastlane. See this page for details.
brew install fastlane
System Ruby + RubyGems (macOS/Linux/Windows)
This is not recommended for your local environment, but you can still install fastlane to system Ruby's environment. Using
sudo often occurs unwanted results later due to file permission and makes managing your environment harder.
sudo gem install fastlane
Setting up fastlane
Navigate to your iOS or Android app and run
fastlane will automatically detect your project, and ask for any missing information.

Questions and support
Before submitting a new GitHub issue, please make sure to search for existing GitHub issues.
If that doesn't help, please submit an issue on GitHub and provide information about your setup, in particular the output of the
fastlane env command.
Currently, fastlane is officially supported to run on macOS.
But we are working on 🐧 Linux and 🖥️ Windows support for parts of fastlane. Some underlying software like Xcode or iTunes Transporter is only available for macOS, but many other tools and actions can theoretically also work on other platforms. Please see this Github issue for further information.
Special thanks to all contributors for extending and improving fastlane.
fastlane tracks a few key metrics to understand how developers are using the tool and to help us know what areas need improvement. No personal/sensitive information is ever collected. Metrics that are collected include:
- The number of fastlane runs
- A salted hash of the app identifier or package name, which helps us anonymously identify unique usage of fastlane
You can easily opt-out of metrics collection by adding
opt_out_usage at the top of your
Fastfile or by setting the environment variable
FASTLANE_OPT_OUT_USAGE. Check out the metrics code on GitHub
