Microsoft announced the retirement of Visual Studio App Center by March 2025, prompting developers to seek alternatives for continuous integration and continuous delivery (CI/CD) in mobile app development. With the acceleration of software development cycles, automation has become crucial for seamless app updates, making CI/CD tools indispensable for reducing bugs, errors, and deployment costs while enhancing speed and efficiency. Among the leading CI/CD tools are Jenkins, CircleCI, Travis CI, Bitrise, TeamCity, GoCD, Bamboo, GitLab CI, Codeship, Codefresh, and Codemagic, each offering unique features, integrations, and pricing models to accommodate varying developer needs. These tools support automation of build, test, and deployment processes, enabling developers to release code rapidly and focus on creating business value. As mobile development requires agile, rapid iterations, choosing the right CI/CD solution involves considering factors like features, integrations, support, and cost.
