fastlane

fastlane is an open-source automation toolkit for mobile release work. It wraps the repetitive parts of shipping an app, such as generating localized screenshots, managing certificates and profiles, updating metadata, and uploading builds to TestFlight, the App Store, and Google Play, into lanes you define once and run with a single command. For a solo iOS developer, it turns a manual release checklist into a repeatable script.

It fits almost any iOS developer who releases more than a couple of times, because the lanes run locally or inside any CI. It does not fit if you want a hosted dashboard and managed machines out of the box, because fastlane is a command-line tool you run somewhere, not a service. For that, pair it with Codemagic or Bitrise.

Pricing

fastlane is free and open source under the MIT license, so there is no subscription, seat, or usage fee for the tool itself (checked July 19, 2026). Your only costs are indirect: the machine or CI minutes where the lanes run, since fastlane still needs a Mac to build and sign an iOS app. Pricing last checked July 19, 2026; confirm the current license and project status on the official site.

Setup and integration

fastlane installs through RubyGems or Homebrew and runs on macOS for iOS work. You initialize it in your project and define lanes in a Fastfile. Common building blocks include match for shared, git-stored code signing, snapshot for localized screenshots, deliver for metadata and store upload, and pilot for TestFlight. Effort is moderate up front and pays back on every later release.

Two gotchas are worth knowing. match changes how code signing works by storing certificates in a git repository, which is powerful but needs a deliberate setup and access control. Because fastlane depends on Ruby and the Xcode command-line tools, version drift between machines can break lanes, so pinning versions helps.

Frequently asked questions

Is fastlane really free?

Yes. fastlane is open source under the MIT license, with no paid tier for the tool (checked July 19, 2026). The only costs are the machine or CI minutes where you run it, since building and signing an iOS app still requires a Mac.

How does fastlane compare with Codemagic?

They solve different layers. Codemagic is hosted CI that provides the machines and a dashboard, while fastlane is the automation you run on those machines. Many setups use both: fastlane defines the lanes, and Codemagic or Bitrise triggers and hosts them. You can also run fastlane entirely on your own Mac with no CI at all.

Do I still need App Store Connect if I use fastlane?

Yes. fastlane automates the steps against App Store Connect, such as uploading builds, metadata, and screenshots, but you still create the app record, products, and agreements there. It removes the repetitive clicking, not the account.
