Jenkins is among the most sought-after tools implemented in the DevOps environment to achieve Continuous Integration and Continuous Delivery (CI/CD). However, many developers and experts often feel that Jenkins cannot fulfill all requirements when it comes to specific project criteria regarding CI/CD. So, when Jenkins does not seem to be the perfect fit for achieving CI in a development project, there are other alternatives to try out. Some of the most popular choices are GitHub Actions, GitLab, Bamboo, JFrog Pipelines, Spinnaker, TeamCity, AWS CodePipeline, Azure DevOps Server for Java, and .NET projects, CloudBees CI, CruiseControl, Integrity, GoCD, Gradle, and Maven, among others. Some of these tools come with both free and paid plans.
