fastlane vs Qbs

fastlane is a free, open-source platform for automating iOS and Android app development and release workflows. Teams define workflows as lanes and can run them with a single command. A lane can manage build numbering, code signing, builds, beta uploads and changelog creation; fastlane also supports store releases, including metadata and screenshot management and submission for review. It can create localized app store screenshots for the languages and devices an app supports. The site lists support for more than 15 beta testing services, including TestFlight, Crashlytics Beta, Play and Hockey. Documentation describes integrations with more than 400 tools and services, including major CI systems, alongside community-built actions and plugins. For iOS signing, signing identities and profiles can be kept in a private encrypted Git repository and synced between machines. fastlane runs on a user's machine or server, and its documentation says credentials and other sensitive information stay there. macOS is officially supported; Linux and Windows are partially supported. The project uses the MIT license.

Qbs is a build automation tool for managing software projects across multiple platforms. Projects can use it regardless of programming language, toolkit, or libraries, and its declarative model lets them describe build tasks and dependencies without setting the build order. The manual lists correct, fast incremental builds and an extensible architecture among its features. Qbs documents built-in support for Windows, Linux, macOS, Android, iOS, tvOS, watchOS, QNX, and FreeBSD, plus cross-compilation. It can be used with Qt Creator and Visual Studio Code through the Qbs session feature, and it can generate Clang compilation databases. Project generation for Visual Studio, IAR Embedded Workbench, and Keil uVision is available but described as experimental. Binaries are available for Windows, macOS, Linux, and FreeBSD, or Qbs can be built locally from source. The Qbs plan costs nothing. Its library and tools are available under commercial licenses, LGPL version 3, and GPL version 2. The Makefile generator will not create a Makefile if the source, build, or install root directory contains spaces; other UNIX-like systems may work but are not regularly tested or officially supported.
