20 Best Continuous Integration Tools: A Guide to Optimizing Your CI/CD Processes

The CI/CD pipeline is key to creating a robust DevOps process that will deliver stable products to market faster.

Continuous integration (CI) tools are the engine that drives today’s SaaS software development strategy across all business, corporate, consumer, and industrial boundaries. CI is crucial to streamlining development processes and providing engineering teams with real-time insights on software deployment.

Continuous delivery (CD) is the next level of continuous integration and is vital to delivering stable software to a test environment so developers can determine whether the software is releasable.

A CI/CD pipeline helps automate steps in the software delivery process, such as initiating code builds, running automated tests, and deploying to a staging or production environment. Automated pipelines remove manual errors, provide standardized development feedback loops, and enable fast product iterations. An effective CI/CD strategy can automate the process all the way to deployment in production environments so customers can see changes sooner.

CI/CD workflows aren’t immune to security concerns. To address these, we recommend integrating security into your DevOps model (something commonly known as DevSecOps). By pairing leading continuous integration tools with a comprehensive security solution like Threat Stack’s Cloud Security Platform, organizations can develop more reliable and secure applications, without compromising their team’s efficiency. Including Threat Stack in your model would enable you to achieve full-stack security observability.

While countless CI/CD tools are available to fit a variety of needs, this post compiles 20 of the most widely used as well as a cross-section that are suited to specific different development needs and teams.
