GitHub Actions vs GitLab CI vs Jenkins: Choosing a CI/CD Pipeline for Your Web App in 2026

Choosing a CI/CD pipeline affects how quickly your team ships features, the reliability of your web application deployments and how much time your engineers spend managing infrastructure. For small- to medium-sized web development teams, GitHub Actions is the obvious choice if your code is in GitHub; GitLab CI/CD is a great choice if you are looking for an integrated development, security and operations platform; and Jenkins is a great choice if your team is looking for a highly customized and/or self-hosted solution.

However, price is not always an indicator of the best choice. The true cost of ownership takes into account runner infrastructure, security configurations, pipeline and system maintenance, and the reliability of the deployment system. Xcentric Services can help you plan and implement CI/CD workflows that support your application and release process. Explore our cloud and DevOps services to help you plan a pipeline tailored to your development team.

Comparison of GitHub Actions, GitLab CI and Jenkins

In general, GitHub Actions is a great choice if your code lives in GitHub, GitLab CI/CD is a great choice if you are looking for an integrated Development and Security platform, and Jenkins is a great choice if you are looking for a fully self-hosted/customized solution.

GitHub documents its workflow and runner model in its Actions documentation. GitLab documents its integrated CI/CD capabilities and plan differences in its pricing and feature comparison. Jenkins documents its pipeline model in the official Jenkins documentation.

For a web application built with React, Next.js, Node.js or similar, all three can automate dependency installation, testing, building and deploying.

What is GitHub Actions and Who Should Use It?

GitHub Actions is built into GitHub, so teams building and deploying web apps automatically via GitHub, and wanting integrated tests and pull request checks, should consider it.

YAML files define workflows in the .github/workflows/ directory. There are multiple event types that can trigger jobs, such as pull requests and pushes.

A good example of a GitHub workflow is with a startup that uses Next.js for the frontend and Node.js for the API. When a pull request is created for the front-end changes, we can run linting and unit tests, and build the frontend for production. A different workflow is used to deploy the app to staging. Once the application passes all the required validation and tests for production, we promote it to production using the same workflow.

GitHub Actions allows workflows to be defined at a granular level for a small engineering team, eliminating the need for a homegrown automation solution.

What are the Use Cases for GitHub Actions?

It is best used when the repositories are already on GitHub, code changes are implemented via pull requests, and CI/CD as well as code reviews need to be in one place.

Unless security and costs are properly configured, problems can arise due to unpinned third-party actions and large number of parallel jobs. A team needs to properly distinguish between a GitHub subscription and costs associated with GitHub runners.

For businesses embarking on a large-scale application modernization project, CI/CD should be reviewed as part of the changes as well. Our Docker vs Kubernetes guide covers container orchestration and application packaging.

What are GitLab CI/CD and GitHub Actions?

GitLab's automated testing and deployment, CI/CD, is contained within their development platform. Engineering teams can find value with GitLab as they provide repository management, merge requests, pipelines and security reporting within a single platform.

To configure pipelines, teams edit a .gitlab-ci.yml file. Jobs are grouped into stages, and GitLab Runners are responsible for their execution. Teams can leverage GitLab-hosted Runners or administer their own Runners for control over the build environment.

GitLab's integrated security workflow is available in all tiers. The Free tier does not offer much, if any, integration with scanning results. The Premium tier extends scanning results integration and management. In the Ultimate tier, scanning results integration and management are provided along with governance of advanced analyses and vulnerability management.

How do GitLab CI and GitHub Actions compare?

The main difference is integration with their respective platforms. GitHub Actions is event-driven and integrated with the GitHub platform via a marketplace of actions, while GitLab CI/CD is part of a broader integrated platform with repositories, pipelines, planning and security features.

GitLab CI/CD (GitLab) is used by companies to keep processes consistent when development teams work in a decentralised manner. GitLab includes many features and is a complete DevOps platform, compared to GitHub, which is better for its workflow integration.

Security workflow Depending on the plan Features vary by tier

Runner management GitHub-hosted or self-hosted GitLab-hosted or self-managed

Main decision factor Existing GitHub workflow Integrated DevSecOps platform

GitHub Actions, on the other hand, is simpler to implement when teams are transitioning from a completely manual software delivery process. That's because GitHub Actions works with GitHub repositories.

GitLab and GitHub have features that assist teams with security, but that doesn't make applications secure. In both cases, teams need to control access, manage their dependencies, create and implement review processes and deploy applications within the scope of permissions.

What is Jenkins and is Jenkins still relevant in 2026?

In 2026, Jenkins is still suitable for organizations with specialised build environments and instrumentation that is tightly integrated with existing infrastructure. In general, however, Jenkins is not the best choice for teams looking for a simple automation service.

Jenkins is an automation server. It provides a tool to create pipelines, and teams implement Jenkins Pipelines in a variety of ways, using either Declarative or Scripted Pipeline syntax. Jenkins supports a variety of source control systems, testing and deployment tools.

Jenkins is free, but teams need to manage the controller, agents and plugins, as well as perform backups, upgrades and monitor the service.

For a business with an established automation and private build infrastructure, or with special hardware and strict network isolation requirements, Jenkins may be a good choice. Replacing a mature Jenkins installation with a different CI/CD tool carries migration risk.

Jenkins support policy states that the supported runtime versions of Jenkins may change. Supported releases of those runtime versions of Jenkins may also change. Plugin support policies state that plugin versions may change with Jenkins versions. So, to upgrade to a newer version of Jenkins, teams may also need to plan for a corresponding upgrade of Java (if the support policy for Java indicates an upgrade is needed).

For a small SaaS company, GitHub Actions would likely need less infrastructure administration compared to Jenkins. But if the control and flexibility of Jenkins helps address a key operational issue, then Jenkins may be the better choice.

Jenkins vs GitHub Actions: How Much Does Each CI/CD Tool Cost Per Month?

For 10 developers on a web team, running approximately 3,000 build minutes per month on Linux, GitHub Actions and GitLab Premium have predictable, relatively low-cost subscription options. Each option has a lower, predictable cost compared to Jenkins. Estimates assume October 2026 pricing, when available, from the vendors. See GitHub pricing page, GitHub Runner pricing and GitLab pricing page.

Pricing source and date: Official vendor pages checked 19 October 2026. This comparison assumes eligible standard Linux runner usage within allowances. Taxes, storage overages, add-ons, larger runners and separately billed cloud resources are excluded. Check current pricing before purchasing.

For Jenkins, a responsible budget should include the server, backups and monitoring, as well as engineering time. There is no defensible monthly total without understanding infrastructure specs and maintenance rate.

The Jenkins vs. GitHub Actions cost comparison highlights that pricing a subscription service solely on a per-unit basis is insufficient. A managed service may cost more with licensing, but give time back to engineers that would be spent managing the service.

While GitLab Premium’s per-user costs may seem high, it can be justified if a team can benefit from GitLab’s collaboration, support and enhanced CI/CD features. Additional security features, like advanced reporting and vulnerability management, can be found in GitLab’s Ultimate plan. Features in Ultimate should not be assumed to be included in Premium.

Before a decision on a platform can be made, various metrics relating to the DevOps pipeline must be measured. These include the number of build minutes, the average pipeline duration, concurrency, available storage, runner size and the time spent investigating and resolving failed deployments. Xcentric Services can assist customers with these measurements.

GitHub Actions vs Jenkins: Security, Secrets and Supply-Chain Risk

GitLab CI/CD and Jenkins, as well as GitHub Actions, can all be configured to support the secure delivery of web applications. Additional controls such as short-lived credentials, restricted deployment roles and controlled access to production can help secure application deployments to AWS.

How do you Deploy to AWS Using OIDC Instead of Access Keys?

With CI/CD and OpenID Connect (OIDC), a trusted identity token can be used to request temporary AWS credentials, thereby eliminating the need to use long-lived AWS access keys, which are stored in repository secrets. This can help reduce the risk of credential leaks or losses.

AWS outlines this approach in its IAM OIDC Federation document. Other resources detail the restricted trust policy to be used by the IAM role. The CI/CD pipeline controls the resources to be deployed and the permission required to do so.

Jenkins, as well as GitLab CI/CD, can be configured to make use of OIDC identity federation with AWS, if the required integration and configuration can be done. Use the documented authentication methods and deployment credentials for Vercel. Limit access to deployment environments and do not log credentials. Refer to the Vercel documentation to decide which integration to use for deployment.

If you are assessing application-level controls, Xcentric's best practices for securing APIs are relevant.

How do Third-Party Actions and Jenkins Plugins Affect Supply-Chain Risk?

Plugins or components implemented in a pipeline increase its functionality; however, they also create dependencies. Compromised components or plugins can expose repository secrets and/or deployment permissions.

The following controls can be applied:

• Pin third-party actions to verified commits and review changes before using them.

• Do not implement unused plugins; monitor and review updates.

• Avoid giving pull request workflows deployment permissions.

• Secure the process that promotes builds to production.

• Do not use the same credentials for testing and deployment.

Protect the application artefacts produced by the pipeline. Where the architecture of the application permits, build once, and promote the same versioned artefact through all stages, including production.

For Next.js projects deployed on Vercel, the deployment stage can make use of the supported integrations. Teams evaluating frameworks can also refer to Next.js vs. Nuxt.js for SEO.

GitHub Actions Alternatives: What Should You Expect When Migrating from Jenkins?

Migrating from Jenkins to GitHub Actions or GitLab CI/CD means converting a Jenkinsfile to YAML and migrating credentials, runner configuration, shared libraries, deployment policies, artifacts, and environment monitoring.

The more embedded business logic in the Jenkins configuration, the more effort the migration will take. Embedding a lot of business logic in a continuous integration (CI) configuration can lead to a brittle and hard-to-maintain system. This is amplified when dealing with Jenkins due to its distributed nature.

Migrating Jenkins jobs to a different CI system usually follows the same process. Start with an inventory of jobs, plugins, credentials and deployment targets, and migrate one job at a time, starting with an easy case to gain confidence and understand potential issues. Validate migration by verifying build and test outputs, privilege/security level permissions, artifacts and rollbacks.

Pipeline logic: Groovy scripts, shared libraries and conditions

Credentials: Stored secrets and service accounts

Build agents: OS, tools and hardware

Artefacts: Build outputs and containers

Releases: Approvals, rollbacks and access to production

Stay away from migration for the sake of migration. If your current implementation of Jenkins works for your company, then improving your pipelines can be more cost-effective than migrating to a different platform. If your engineering team is spending a great deal of time and effort simply maintaining the system, it may be worth it to look at a more fully managed solution.

Xcentric's cloud migration strategy guide may help frame the surrounding application and hosting decisions for more widespread infrastructure planning.

Jenkins vs GitLab CI: Which CI/CD tool should your business choose?

For small- to medium-sized web development teams, the right CI/CD tool is the one that integrates with your deployment, security, and operational needs, and creates the least amount of maintenance burden. GitLab CI/CD is the right choice for teams looking for an integrated DevSecOps solution, and Jenkins is the right choice for teams that need a great deal of control and customization.

Choose GitLab CI if you need pull request automation and integrated security and scanning features.

When your team is ready to incorporate code management, pipelines, planning, and security into a single platform, consider GitLab CI/CD. Compare the various tiers to see what options are available for your security reporting and vulnerability management needs.

Jenkins is a great choice when your team must work in an air-gapped environment, require special build agents, or seek a significant amount of control and flexibility over the execution environment with established plugin integrations.

The final decision should consider the opportunity cost of developer time as well as the cost of vendor services. A pipeline that reduces the cost of a developer service subscription by a few hundred dollars may actually cost more over a year, due to the time required for manual intervention.
