    Today, more and more companies are recognizing the key role of automation in their software development process, and test automation in particular. Many companies adopt continuous integration and continuous delivery in order to release new features faster. This requires using a dedicated CI/CD tool that will automate the process of integration, testing, and deployment of new code changes.

    There are many CI/CD tools available in the market and multiple factors to consider when choosing one such as costs, integration with other tools, and support. Let’s explore CI/CD, its benefits, and compare the top 8 CI/CD tools.

    Top 8 CI/CD Tools

    What is CI/CD?

    The term CI/CD refers to two practices: continuous integration and continuous delivery. These practices are used mainly in a DevOps approach in order to automate the entire process of software development, testing, and deployment. Automating this process improves team speed and accuracy, as well as overall software quality.

    CI/CD begins with Continuous Integration, which is the process of merging new code changes from multiple developers into a shared repository. Since the process is automated, developers can integrate their code changes without waiting for other developers to finish their work.

    After the integration of code changes, the next step is Continuous Delivery. This involves automatically building, testing, and deploying the code changes to a staging environment. This environment simulates an actual production environment, enabling developers to test their code changes in a real-world scenario before live deployment. The Continuous Deployment process then takes over, which automatically deploys code changes to the live environment.


    Why use CI/CD Tools?

    The main advantage of CI/CD tools is automation, which significantly decreases the time and effort required to release software while increasing accuracy and reliability. Here are some of the other benefits companies can gain from using CI/CD tools:

    • Automation saves time and effort in releasing higher quality software.
    • Faster product delivery without additional intervention from human employees.
    • Shorter development cycles and streamlined workflows.
    • Enablement of automatic tests such as unit tests and integration tests to identify bugs and issues before deployment.
    • Identification of errors earlier in the development process to prevent problems for users and save company resources.
    • Improvement of a company’s agility and responsiveness in the market provides a competitive advantage.


    Jenkins's logo Jenkins is an open-source CI/CD tool for automating the software development lifecycle.
