CI/CD tools are an essential part of DevOps and agile practices. These tools help save time and money by automating tasks, preventing bugs, and encouraging collaboration.

However, choosing the right CI/CD software is not easy. Different tools come with different functionalities, so you need to know what every option has to offer.

This article introduces the best 22 CI/CD tools available for use. Read on to simplify your selection process and find the right fit for your DevOps team.

What is CI/CD?

CI/CD is the acronym for Continuous Integration and Continuous Delivery:

  • Continuous integration (CI): Continuous integration is the practice of introducing code changes from several contributors to a single project. The CI process also typically includes code testing.
  • Continuous delivery (CD): Continuous delivery gets code changes of all types into production safely and quickly. The main idea in CD is to turn updates into routine tasks a team can perform on-demand.

CI/CD enables organizations to respond to market and customer demands quickly. These practices grant teams the agility to develop software efficiently without compromising quality.

CI/CD tools orchestrate CI/CD practices. Once set up, the tool acts as the central hub for all CI/CD activity. Automation saves time and ensures quality with frequent tests.
