Gitlab vs Jenkins has been a popular debate among developers for a long time. While most of the coders like Jenkins, developers cast their votes for Gitlab. Both Jenkins vs Gitlab CI/CD tools have certain strengths and weaknesses. Let’s dive into the ultimate comparison of Gitlab and Jenkins without further ado.
Jenkins is a popular open-source automation tool that enables businesses of all sizes to seamlessly build and manage Continuous Integration and Continuous Delivery (CI/CD) pipelines by allowing you to add multiple programming languages, repositories, and pipelines, Jenkins makes it possible to integrate every type of automation solution.
Before receiving the name we all know today, Jenkins was actually called Hudson. Its creator, Kohsuke Kawaguchi was working in Sun MicroSystems as a software developer. Hudson was the result of a constant struggle that Kohsuke faced when he was creating and breaking builds. To make his work easier, he wanted to see if the build works before committing it to the repository. The outcome was Hudson, an automation tool for Java that allows developers to identify and resolve integration problems early in the development process instead of later when they are more difficult to resolve. Initially, it was written for Sun MicroSystems but it was later offered as open-source for other companies.
When Oracle acquired Sun, a dispute arose about the management of Hudson. The result was a new fork of Hudson formed by the Hudson open-source community called Jenkins. While both forks existed for some time, Hudson was closed in early 2020. Jenkins joined the Continuous Delivery Foundation (CDF), an open-source foundation and a part of the Linux Foundation that includes companies such as Google.

Gitlab is an open-source code management and CI/CD tool. It was initially designed to manage code repositories. Later, it was extended to support a complete DevOps platform, providing end-to-end DevOps capabilities. It enables organizations to seamlessly collaborate with members across teams working on all project-related tasks such as project planning, code repository management, monitoring, and security. By allowing administrators to set permission at one time and then access all resources, Gitlab enables them to easily integrate various solutions and works as a team to build better software. It can be termed as a full-fledged tool to manage the complete DevOps ecosystem.
The Gitlab software was created by Valery Sizov and Dmytro Zaporozhets in 2013. The software was written in Ruby, and Go was used to rewrite some parts later on. The current tool involves Ruby on Rails, Go, and Vue.js programming languages. GitLab Inc. was launched in 2014 with San Francisco as its headquarters. Initially, it was free and open-source. In 2013, it was split into two versions; Enterprise and Community Editions. In 2017, the company announced that Gitlab would be offered as an open-source tool under an MIT license. Today, GitLab is available in three editions; Free, Premium and Ultimate. The company operates in 65 countries with 1630 employees.
When it comes to pricing models in the jenkins vs gitlab CI/CD battle, Jenkins is open-source and accessible for all users. So, you can save significant investment on licensing costs. The only price you’ll need to manage would be the hosting expense of the server to update and maintain it.
As mentioned before, GitLab was initially offered for free and open-source under the MIT license. Currently, the company offers three packages. The first one is the free version that offers 400 CI/CD minutes per month. It includes 5 GiB storage and 10 GiB data transfer per month. The premium version charge is $29 per user per month, billed annually, and offers 10,000 CI/CD minutes per month along with 50 GiB storage and 100 GiB data transfer per month. It includes additional features such as project management, ops insights, release controls, etc.
The Ultimate version contains 50,000 CI/CD minutes per month, 250 GiB storage and 500 GiB transfer per month. In addition to all the features of the Premium edition, the Ultimate edition provides you with advanced features such as portfolio management, compliance or value stream management, advanced security controls and some other extras. The plan includes unlimited free guest users and comes with a custom pricing model.
When it comes to installation, Jenkins is an easy tool to set up. All you need is JRE installed on your machine. It supports Windows, Unix, and Mac platforms. You can run it as a java servlet in GlassFish, Apache Tomcat, or any other Java container; it also works with Docker. You just need to download the file and run the normal installation process. Jenkins War file comes bundled with a Jetty servlet container wrapper called Winstone that runs on any Java-supported platform or OS. Jenkins is self-hosted and available on-premise too. The configuration of the tool is pretty simple. You can easily configure it using the web interface. The upgrade process is also a no brainer. Extensive documentation is available for every task.
The GitLab installation process is pretty straight forward. However, it only supports Unix-based platforms such as CentOS, Linux, OpenSUSE, RedHat Linux, Debian, Ubuntu, etc. It doesn’t support Mac or Windows platforms. To run GitLab on these platforms, you need to go through a round-about process.
Updating GitLab is straightforward. GitLab offers extensive documentation to walk you through this process. However, the process and complexity might increase depending on the installation method used like Docker, Linux packages (Omnibus), Helm chart (Kubernetes) or self-compiled (source). GitLab is available as self-hosted and on-premises.
As for the Gitlab vs Jenkins plugin support, Jenkins offers an extensive bundle of plugins for every type of CI/CD task. There are more than 1700 plugins available for users that can be easily customized. The plugins are regularly updated. You can integrate these plugins with other DevOps tools as well. Jenkins is significantly extensible owing to its huge plugin portfolio. Whether you want to perform a single task of integrating build processes or manage the entire product development lifecycle, Jenkins makes it easy.
When compared with Jenkins, Gitlab plugin support is limited. However, it offers the necessary plugins to support you at every stage of DevOps.
Jenkins doesn’t offer a built-in CI feature, but it provides an easy way to set up continuous integration and continuous deployment for various code repositories and languages using pipelines. It allows you to integrate the entire development technology stack to deliver products faster and better.
Gitlab comes with a built-in CI/CD feature that helps you quickly set up CI/CD pipelines. Auto DevOps is another powerful feature of Gitlab that makes software delivery easy, efficient, and automated. It uses predefined default CI/CD templates that scan your code language and automatically build, test and deploy tasks. It also includes vulnerability testing and secure auditing that proactively scans the project for vulnerabilities, licensing issues, security flaws, etc. Auto DevOps can be applied at project level, group level, or instance level. Gitlab gets an edge here in the GitLab vs Jenkins CI/CD battle.
GitLab Runner Autoscaler is a handy feature of GitLab that allows you to configure Auto-scaling for CI runners and save 90% of EC2 instance costs. This feature can be applied across the repositories at a project or organizational level. It supports AWS EC2 instances, Google Compute Engine and Microsoft Azure Virtual Machines. When it comes to platforms, the instance executor supports Linux, Windows and macOS. The Docker auto scaler executor does not support macOS.
When it comes to Jenkins, the auto-scale option is rather complicated to make changes to the Jenkins architecture workflow. A script is required to install a software on Jenkins runners to provide an automated way to register with Jenkins Primary and then disconnect before termination. In addition, it is important to set up and monitor auto-scale triggering events using a tool like CloudWatch.
One of the key reasons for the success of Jenkins is its community support. Right from installation to usage, the Jenkins community is ready to offer support for any type of task. On the other hand, I must mention that while documentation is available, there is no dedicated technical support team.
When it comes to Gitlab, dedicated technical support is offered for paid users 24×5, while for free users, extensive documentation is available, and a great support is enhanced by its community.
By allowing you to concurrently run multiple builds across multiple virtual machines, Jenkins makes it easy for developers to continuously and quickly test their code. Gitlab also facilitates parallel execution. It clones the job and runs it in parallel in the background.
Jenkins REST API supports XML, Python, and JSON with JSONP support, enabling you to extend its functionality. Gitlab offers a REST API for projects, groups, and standalone ones. Currently, API version v4 is only available. You should include the API and the version number while making an API request.
Jenkins makes it easy for you to perform CI/CD tasks as you can distribute workloads such as builds, tests, and deployments across multiple machines, platforms, and regions. With distributed workloads and parallel execution, it has faster lifecycles with reduced time frames.
Gitlab allows you to configure parallel execution in the YAML file. Based on the availability of runners, it performs similar operations. Gitlab also supports distributed scaling, so you can scale out builds on different devices.

Take a look at our slideshow to have an overview of the debate between Gitlab vs Jenkins.
Build, test and deploy are the three important components of a software development project. And in the Jenkins vs GitLab CI/CD debate, they offer sufficient support to accomplish these tasks. Jenkins is heavily focused on continuous integration. It is open-source and completely free. It comes as self-hosted and on-premise, a good bet for startups and medium-sized businesses that lack the required budget and expert staff. With Jenkins, you can take advantage of costs. It is easy to learn and work with. The web UI allows you to easily manage processes, orchestrate and automate jobs.
Gitlab outperforms Jenkins when it comes to version control and code collaboration. It enables the user to easily monitor the entire code repository along with all branches. With Jenkins, you can only monitor some branches. When your development teams are spread across multiple geo-locations, Gitlab serves a good purpose. The second consideration is the price. While Jenkins is free, to use all features of Gitlab, you need to have a subscription
In Gitlab, every branch contains the GitLab-ci.yml code which means you can easily modify the workflows. For instance, if you want to run unit tests on one branch and perform functional testing on another branch, you can simply modify the yml configuration for CI/CD steps, and the Runner will perform the job for you.
Nvidia, Goldman Sachs, Siemens, and Thomson Reuters are a few notable companies that use Gitlab. Amazon, Facebook, Google, Infosys Ltd, and Fujitsu Ltd. are a few popular companies that use Jenkins.

Jenkins uses a Master-Slave architecture. The core components of this architecture are the Jenkins Server that acts as a Master, Jenkins Slave machine, and a remote code repository machine. The master controls build operations, checks the code repository and pulls the code when it detects a commit. Then it distributes this workload to slave machines which will run the builds and tests to generate the reports. A great advantage of the Jenkins architecture is that it allows you to use various builds running on multiple machines and on different platforms simultaneously.
Gitlab architecture comprises two essential components, namely Gitlab CI/CD and Gitlab Runner. The Gitlab CI/CD tool is a web interface that enables you to manage builds. The Gitlab runner executes codes to run your builds. Both tools work together to manage and run builds. Gitlab Runner takes the script from the GitLab-ci.yml file via APIs and runs the script. The good thing with Gitlab is that it works with repositories such as GitHub, BitBucket, etc.
Here is a basic Jenkins pipeline:
Here is how Gitlab works:
The GitLab vs Jenkins CI/CD debate is an evergreen topic because both tools offer useful features. Jenkins supports multiple languages and offers a large plugin library. The tool comes with an intuitive interface making it easy to perform tasks such as setting up nodes, debugging runners, or deploying code. It is feature-rich and is flexible to use and edit configurations. Being self-hosted, Jenkins gives you more control over workspaces. Credential management is easy.
On the downside, the lack of pipeline-tracking analytics is a concern. Another challenge is configuring plugin integration and setting up the tool which ultimately increases the overhead for this task.
Gitlab is a complete DevOps tool that takes care of all development tasks. Git version control system comes built-in with this tool. Therefore, the integration with other solutions, addressing ticketing, etc., becomes easier.
Business insights are a crucial feature of Gitlab that allows you to gain clear insights into the impact of changes on the product’s performance. User statistics help you to track resource usage and optimize processes. However, this feature is only available for paid users. Another vital feature is issue tracking. With the help of features like thread discussion, labels, Task Lists, etc., you can easily track and assign issues to quickly resolve them. Moreover, you can import issues from JIRA. Merge management helps you to collaborate and version control projects easily.
Gitlab enables parallel execution with phases which makes it easy to scale runners. Adding jobs and managing conflict issues is easy. The project is more secure with the right privacy policies. The tool easily integrates with Docker. Request integration can be easily merged.
On the downside, it increases the complexity and effort as you need to define and upload/download artifacts for each job. The actual merge should happen before you can test a branch’s merged state.
As the GitLab vs Jenkins CI/CD battle continues, several other CI tools enter the fray.
Bamboo CI is a popular CI/CD server offered by Atlassian. It helps you create different stages of product development to create and deploy quality and bug-free products faster. For instance, you can set up triggers for each commit in a build. It means when a commit is made, it automatically triggers test suites, enabling you to easily catch bugs and resolve issues at the earliest stage. The striking feature of the Bamboo CI server is that it comes from Atlassian, which offers some well-known software development products such as JIRA, BitBucket, FishEye, etc., As such, Bamboo CI makes it easy to integrate with issue tracking and repository tools to seamlessly work on development projects.
CircleCI is a popular CI server that lets you run everything in the cloud, which means you don’t need a dedicated server. It also eliminates maintenance costs. Alternatively, you can also self-host the CI server for better control. Almost 30,000 organizations use CircleCI, and it runs about 1 million tasks every day. It helps you automate parallel execution to deliver quality products faster. It is easy to set up and use. You can store all settings in a single YAML document. Debugging is easy. The UI is intuitive and easy to navigate. Built-in support for Docker workflow is available.
TeamCity is another popular CI server coming from JetBrains. It supports all major platforms such as Windows, Linux, macOS, FreeBSD, Solaris, etc.. TeamCity runs in a Java environment and is easy to install and configure. It can be easily integrated with Visual Studio and other IDEs. GitLab and Bitbucket server pull requests are supported and native GitLab integration is available. Initially, the tool was offered as an on-premise service. The company introduced TeamCity Cloud, a managed CI/CD service in 2021. While it offers a free version, the licensing cost for build agents is around $359 per year.

Gitlab and Jenkins are the two most popular CI/CD tools available in the market due to the features they offer to users. Both the tools were designed to automate CI/CD processes and are separated by just a thin line in the DevOps race. Both tools come with their pros and cons. While Gitlab gets an edge in code collaboration and version control, Jenkins fares well in continuous integration. As such, you cannot rate one tool over the other in the Gitlab vs Jenkins CI/CD battle.
While choosing a CI/CD tool, you need to consider your budget, technology stack, project requirements and in-house proficiency.
Whatever tool you choose, we’re here to help you with your DevOps projects, just reach us at clickittech.com!
Both Jenkins and Gitlab are designed to serve different requirements. While Jenkins boasts of a large plugin shelf, Gitlab is a comprehensive DevOps tool. While multiple plugins do your job efficiently, integration and management of these plugins might become a challenge when the project scales up. Gitlab offers SLA support. However, the initial costs and configuration complexity can also become an issue. It all comes down to your project requirements, in-house proficiency, budgets, etc.
Top 5 Continuous Integration Tools are Jenkins, Gitlab, CircleCI, Bamboo and Teamcity. As each CI tool comes with its pros and cons, you cannot rank them for a single metric. However, Gitlab and Jenkins are the most popular CI tools available in the market.
Jenkins doesn’t offer issue tracking out-of-the-box. Gitlab provides a Gitlab Issues Board that helps you to track and resolve issues.
Gitlab tracking board can be used in 4 ways:
Workflow Tracking
Milestone Planning
Cross-functional Planning
