Enterprises are making their moves toward DevOps methodologies and Agile culture to accelerate delivery speed and ensure product quality. In DevOps, a continuous and automated delivery cycle is the backbone that makes fast and reliable delivery possible.
This results in the need for proper continuous integration and continuous delivery (CI/CD) tools. A “good” CI/CD tool can leverage teams’ current workflow, to best exploit the automation feature and create a solid CI/CD pipeline, and give teams the boost they need to thrive. If you are new to CI/CD, please check out this blog.
With the overflowing number of CI/CD tools available in the market, teams may struggle to have to make difficult decisions to pick out the right tools. This list contains the “Best 5 CI/CD tools in the market”, along with their key features, to make the selection process easier for you and your team.

- Supports up to 100 remote build agents
- Run batches of tests in parallel and get feedback quickly
- Creates images and pushes them into a registry
- Per-environment permissions that allow developers and testers to deploy to their environments on-demand while the production stays locked down
