20 Awesome Continuous Integration Tools, Adopting a continuous integration approach is one of the best things your team can do in terms of improved efficiency. And since its success relies heavily on continuous integration tools, you have to carefully select the ones that fit your needs best. We’ve looked at 20 of the most popular continuous integration tools and listed their advantages to help you choose among similar options.
But before we get down to discussing top continuous integration tools, let’s take a moment to define what continuous integration means.
What is Continuous Integration?
Continuous integration (CI) enables multiple developers to contribute and collaborate in a shared codebase at a rapid pace. This practice is essential to high-velocity teams in high-stakes software roles. Without continuous integration, developer collaboration is a tedious manual process of coordinating code updates and merges.
One of the key benefits of integrating regularly is that you can detect errors quickly and locate them more easily. As each change introduced is typically small, pinpointing the specific change that introduced a defect can be done quickly.
Why is Continuous Integration so Important?
- CI helps to avoid merge conflicts, difficult-to-fix bugs, duplicated code, and discrepant coding strategies.
- CI helps to decrease code review time and makes the project code more homogenous.
- CI speeds up the development process and pushes releases closer.
- CI ensures continuous feedback.
- CI helps to reduce the project backlog.
How to Choose the Best Continuous Integration Tools?
Currently, there is a wide range of continuous integration tools you can choose from. Keep looking further if the tool you selected doesn’t have the following technical features.
What features great continuous integration tools have to offer:
- Robust ecosystem. A Continuous Integration (CI) tool aims to speed up the project release and take extra efforts out of the development process. Before incorporating the tool, make sure it does not create any bottlenecks for your project.
- Cloud compatibility. A good CI tool should allow transferring data to and from the cloud without any problems.
- Deployment options. A CI tool should allow for trouble-free deployment.
- Integration options. Your CI tool should be capable of integrating with other tools and services that are used on the project.
- Safety and security. A useful CI tool, whether commercial or open-source, should not pose any security threats to your project data.
