Open-source Appcircle alternatives

fastlane is a command line tool for iOS and Android developers that automates the repetitive parts of shipping a mobile app. Typical jobs include generating screenshots, dealing with provisioning profiles and code signing, building the app and releasing it to the stores or to testers, all scripted so that a release becomes one repeatable command.

It is written in Ruby and organized around lanes that chain together reusable actions, which you can run on a laptop or on a CI server. The project documentation lives at docs.fastlane.tools. When something goes wrong, the maintainers ask users to include the output of the fastlane env command in bug reports, and to label regressions so they can be tracked quickly.

fastlane is MIT licensed and maintained by a small core team with help from many contributors. It is open-source tooling you run yourself, so there is no hosted service involved. Mobile teams use it to cut manual release work and keep builds consistent between developers and CI.

Jenkins is an open-source automation server written in Java. Teams use it to automate parts of their development workflow, including building projects, running tests to catch bugs early, performing static code analysis and deploying software. The README states that more than 2,000 plugins extend it to automate nearly any task. It is released under the MIT license, and its topics include continuous integration, delivery and pipelines as code.

The project distributes official downloads as WAR archives, Docker images, and native packages or installers for several Linux distributions and Windows. Two release lines exist: weekly releases carrying all new features and fixes, and Long-Term Support releases that receive periodic backported bug fixes. The repository links to contributing guidelines, good first issues, developer documentation, governance and adopters information. As a self-managed server, you operate and secure your own Jenkins instance.
