Best Continuous Integration Tools for 2024 ‒ Survey Results

Continuous integration (CI) and continuous delivery or deployment (CD) are key DevOps practices that provide teams with rapid feedback on their latest code changes and help improve code quality. With a good CI/CD process in place, software development teams can move toward more frequent releases, thereby delivering more value to users and benefiting from their feedback.

The rising importance of CI/CD is evident as 44% of developers now confirm regular usage of CI/CD tools, with a significant 22% having adopted a new tool within the past year. This surge in popularity has led to an overwhelming array of options in the CI/CD tool market, making it challenging to identify the perfect fit for your team’s unique requirements.

To help you navigate this overwhelming landscape of available tools, we present the insights gathered from over 26,000 developers in the State of Developer Ecosystem 2023 report. This comprehensive report covers various aspects of software development, including identifying the most-used CI tools in both personal and professional contexts.

In this post, we’ll go through the most popular CI tools on the market today to help you choose the right one for you and your team.

What is a CI tool?

A CI tool is a platform that automates the process of building, testing, and publishing your software. CI tools integrate with your version control system so they can fetch the latest changes from your repository.

Most CI tools consist of a central server (often known as a build server) and one or more build agents (or runners) that run on separate machines. The build server provides a UI for configuring your build and test pipelines, stores the details of each job, and initiates each pipeline run.

The build, test, and other tasks are distributed to the build agents by the build server. If multiple build agents are available, multiple pipelines can run at the same time, and tasks from the same pipeline can be run in parallel.

You can find out more about CI/CD in our comprehensive CI/CD guide.

What kinds of CI/CD tools are there?

When it comes to choosing the best CI/CD platform for your team, there are several factors to bear in mind.


Whether a CI/CD tool is open-source or a commercial solution is an important consideration. While open-source software is free to use, the only support will be what is provided by others in the community. If you discover a bug or would like a new feature added, you either have to wait for someone else to address it, or you can contribute the change yourself. Whichever way new code is contributed, it may take time for the changes to be reviewed and accepted by the project maintainers.

By contrast, commercial platforms usually include SLAs for technical support, and they deliver regular updates containing new features and bug fixes. Many commercial CI tools offer a free tier, but – unless yours is an open-source project – there’s usually a restriction on the number of concurrent builds you can run or the number of build minutes available.

Cloud-based vs self-hosted options

The move toward using continuous integration and continuous delivery tools in the cloud is in full swing, with more than half of developers (51%) having transitioned to using cloud-based CI tools, and 42% having adopted cloud-based CD tools.

Cloud-based or SaaS CI/CD tools typically include a web UI for managing your build pipelines, with the build agents or runners hosted on public or private cloud infrastructure.

With a cloud-based solution, there is no installation or maintenance required. Once you sign up, you have immediate access to a CI server and can start running your builds on cloud-hosted agents without delay. Some SaaS options also allow you to run builds on your own build agents at a lower cost.

Self-hosted options allow you to choose where both your build server and build agents are deployed: in a private cloud, on on-premises hardware, or in public cloud-hosted infrastructure. The trade-off is that you are responsible for managing installation and upgrades to the CI server and your build agents. With on-premises deployments, you also need to consider scaling and availability of the server and agents.


A CI/CD pipeline touches every stage of the software development process. As such, your CI/CD platform needs to be able to integrate with each element in your toolchain, including your VCS system, issue trackers, team messaging platforms, and deployment environments hosted in the cloud or on-premises.

The integrations available vary by CI tool. Some CI systems are part of an existing ecosystem or are restricted to particular source control systems or VCS hosting services. Others offer the flexibility to integrate with tools from multiple providers and give you the option to extend the platform with plugins or APIs.


Configuring your automated CI/CD pipelines includes everything from specifying the trigger that will initiate each pipeline run to determining the behavior in the event of a failed build or test. These settings may be configured using scripts or from a UI.

While using the UI can be easier for those new to CI/CD and for non-developers, scripts allow you to adopt a configuration-as-code approach with the logic stored in version control. Some tools also give you the option to generate scripts from the UI, giving you the best of both worlds.

How to choose a CI/CD software tool for your pipeline

When choosing a CI/CD platform, consider both your current requirements and how your project is likely to evolve in the future.

Support for your chosen VCS system, programming languages, build platforms, and testing frameworks is a must. However, also bear in mind any plans you may have to migrate to other options in future. Can you combine source code from multiple repos across different version control systems? If you move to a new framework or extend your suite of automated tests, is the CI tool likely to support it? How much freedom is there to customize your pipelines to your workflow or extend the platform’s functionality?

We asked some of our developers at JetBrains how they suggest choosing a CI/CD tool. This response sums up what they had to say:

Choosing a CI/CD platform can depend on many variables.

Are you using a big monorepo but want to make sure your CI/CD only starts for changes in a specific directory?

Which version control systems are in use, and does the tool support them all?

Does the tool quickly support newer technologies, or does it at least let you “shell out” (run a custom CLI tool) to handle your requirements in such a situation?

Having a maintainable CI/CD definition is also important. CI/CD as code is my personal preference, where the definition can be scripted using a programming language like Kotlin instead of a declarative format like YAML.

With CI/CD as code, you can use development tools to refactor and debug build definitions, making it easy to troubleshoot.

Ultimately, choosing a CI/CD platform should be done based on your current and anticipated future needs.

Why do organizations choose custom CI tools?

Building an in-house CI/CD platform allows you to create a solution tailored to your requirements, and 9% of developers reported using a custom CI tool in 2022.

There are several reasons why some teams decide to create their own solution instead of relying on tools available on the market. One is that an in-house tool can be tailored to the team’s specific needs, processes, and workflows more intimately than any other. It can also be designed to be better integrated into complex systems or meet specific requirements.

However, developing your own CI tool entails ongoing development support and updates in the long term. Additionally, the time required for developers to build and maintain the custom platform needs to be factored in.

How can you improve your CI/CD process using CI tools?

Using a CI/CD platform makes it much easier for development teams to automate their CI/CD process so that builds, tests, and other tasks take place automatically, either based on activity in the VCS or following a regular schedule. CI tools provide configuration and integration options so you can build an automated pipeline much more quickly than if you tried to script everything from scratch.

Furthermore, a CI tool should collect the results of every pipeline run, making it easy to monitor the health of your codebase and measure the impact that a regular build and test process has on code quality.

As your team and codebase grow, a CI tool will allow you to scale your build capacity and run jobs in parallel to ensure continued rapid feedback on the latest code changes. CI tools integrated with other developer tools can be invaluable in helping you deliver quality software. 

If you’re looking for ways to get stable builds and improve code quality, JetBrains offers a complete and well-integrated flow with a unified UI – the Space Git flow integrated with TeamCity. Space provides you with Git hosting, code reviews, and quality gates, while TeamCity offers a CI/CD pipeline. Read this article to learn more.


An automated CI/CD process has the potential to improve your software development process dramatically. By providing teams with rapid feedback on their latest work, a CI/CD platform helps you improve code quality while accelerating delivery.

When choosing the best CI/CD tools for your team or organization, looking at the most popular options on the market is a good place to start. However, it’s essential to compare functionality against your own requirements and consider how your projects are likely to evolve in future.

When choosing a CI/CD solution, parameters like language and framework support, performance, and breadth of integrations – from version control systems and cloud infrastructure to issue trackers and messaging platforms – are all vital to consider.
