9 Best CI/CD Tools of 2026

1. 1

   GitHub Actions

   CI/CD built into GitHub that runs workflows on GitHub-hosted or self-hosted runners and bills hosted runners per minute.

   9.4overall

   CI/CD built into GitHub that runs workflows on GitHub-hosted or self-hosted runners and bills hosted runners per minute.

   Best forTeams that host code on GitHub and want the most widely used CI/CD service with low per-minute runner prices.

   Adoption data

   47%In JetBrains' State of CI/CD 2026 survey, 47% of developers said their organization uses GitHub Actions, the highest share of any CI/CD tool.

   JetBrains, The State of CI/CD 2026 (2026): “GitHub Actions leads organizational adoption, with 47% percent of respondents saying their organization uses it, followed by GitLab CI at 32% and Jenkins at 28%.”

   GitHub Actions is the most widely used CI/CD service in this list. JetBrains' State of CI/CD 2026 report finds 47 percent of respondents' organizations use it, up from 41 percent a year earlier, well ahead of GitLab CI at 32 percent. Pricing is easy to model because GitHub publishes a per-minute rate for every runner: $0.006 for a standard 2-core Linux runner, $0.010 for Windows and $0.062 for macOS, with larger Linux runners from $0.012 for 4 cores. Accounts get included compute as a dollar amount each month, $12 on Free, $18 on Team and $300 on Enterprise Cloud, which GitHub says covers 50,000 standard Linux minutes. Public repositories and self-hosted runners do not draw down that allowance. The trade-offs are the high macOS rate and the fact that Actions only makes sense if your code already lives on GitHub. We compared documented features and published prices rather than running benchmark builds.

   Strengths

   • +Highest organizational usage share in JetBrains' 2026 survey, up from 41% in 2025
   • +Standard 2-core Linux minutes cost $0.006, among the lowest hosted rates on this list
   • +Free plan and public repositories cover many open source projects at no cost

   Limitations

   • −macOS runners cost $0.062 a minute, about ten times the Linux rate
   • −Included compute is a dollar amount, so the minutes it buys depend on runner type
   • −Tied to GitHub as the code host

   SummaryGitHub Actions is the first tool to try for any team on GitHub. Watch macOS and larger runner minutes, which drive most bills.

2. 2

   GitLab CI/CD

   CI/CD built into GitLab's DevSecOps platform, with compute minutes included in every plan and self-managed runners.

   8.7overall

   CI/CD built into GitLab's DevSecOps platform, with compute minutes included in every plan and self-managed runners.

   Best forTeams that want source control, pipelines and security scanning in one product, on GitLab.com or self-managed.

   Adoption data

   32%In JetBrains' State of CI/CD 2026 survey, 32% of developers said their organization uses GitLab CI, the second highest share.

   JetBrains, The State of CI/CD 2026 (2026): “GitHub Actions leads organizational adoption, with 47% percent of respondents saying their organization uses it, followed by GitLab CI at 32% and Jenkins at 28%.”

   GitLab CI/CD is the main alternative for teams that want one platform for code, pipelines and security. JetBrains' 2026 survey puts it in 32 percent of respondents' organizations, second only to GitHub Actions, though slightly down from 34 percent in 2025. Pipelines are part of every GitLab plan. Free includes 400 compute minutes a month for up to 5 users per top-level group, Premium costs $29 per user per month billed annually with 10,000 minutes, and Ultimate includes 50,000 minutes at a custom price. Extra minutes cost $10 per 1,000, which works out to $0.01 a minute, and teams can bring their own runners on any plan to avoid minute charges. Static application security testing is included even on Free, and Ultimate adds supply chain security and vulnerability management. The catch is seat cost: a 20-person team on Premium pays $580 a month before any extra minutes. We compared documented features and published prices only.

   Strengths

   • +Second highest organizational usage share in JetBrains' 2026 survey
   • +Code, CI/CD and security scanning live in one product
   • +Generous included minutes on paid plans: 10,000 a month on Premium

   Limitations

   • −Premium costs $29 per user per month, the highest seat price among hosted code platforms here
   • −Free plan is limited to 5 users per top-level group
   • −Ultimate pricing is not published

   SummaryGitLab CI/CD is the best pick when you want code, CI and security in one place. Budget for the $29 Premium seat, since Free is capped at five users.

3. 3

   Jenkins

   A free, open source automation server that teams install and run themselves, extended through community plugins.

   8.6overall

   A free, open source automation server that teams install and run themselves, extended through community plugins.

   Best forTeams that want full control over a self-hosted CI server and have the staff to maintain it.

   Adoption data

   28%In JetBrains' State of CI/CD 2026 survey, 28% of developers said their organization uses Jenkins, the third highest share.

   JetBrains, The State of CI/CD 2026 (2026): “GitHub Actions leads organizational adoption, with 47% percent of respondents saying their organization uses it, followed by GitLab CI at 32% and Jenkins at 28%.”

   Jenkins is the long-running open source option, and it is still common. JetBrains' 2026 survey finds 28 percent of respondents' organizations use it, down from 31 percent in 2025 but ahead of every commercial tool except GitHub Actions and GitLab CI. The project describes Jenkins as the leading open source automation server, with more than 2,300 community contributed plugins that connect it to practically every tool in a CI/CD toolchain. It runs as a self-contained Java program on Windows, Linux and macOS, is configured through a web interface, and can distribute work across many machines. There is no license fee, so the cost is your own servers and the engineers who keep them patched. That is also the main weakness: Jenkins has no hosted service from the project, and teams that rely on many plugins often find upgrades slow. It scores well on value and adoption but lower on features than hosted platforms with built-in runners. We compared documented features only.

   Strengths

   • +No license fee at any scale
   • +Still used in 28% of organizations in JetBrains' 2026 survey
   • +Largest plugin catalog in this list, at more than 2,300 plugins

   Limitations

   • −You run, patch and scale the servers and agents yourself
   • −Plugin sprawl can make upgrades slow
   • −No hosted option from the project itself

   SummaryJenkins is the right choice when you need a free, fully self-hosted CI server and have people to run it. Teams without that capacity should start with a hosted service.

4. 4

   Azure Pipelines

   Microsoft's CI/CD service in Azure DevOps, priced by parallel job with unlimited minutes rather than per minute.

   8.3overall

   Microsoft's CI/CD service in Azure DevOps, priced by parallel job with unlimited minutes rather than per minute.

   Best forMicrosoft and Azure teams that want flat, predictable CI pricing per parallel job.

   Adoption data

   15%In JetBrains' State of CI/CD 2026 survey, 15% of developers said their organization uses Azure DevOps Server, Microsoft's self-hosted edition of the Azure DevOps toolset that includes Pipelines.

   JetBrains, The State of CI/CD 2026 (2026): “Azure DevOps Server stands at 15%, while AWS CodePipeline, custom tools, and Bitbucket Pipelines comprise the next tier.”

   Azure Pipelines takes a different approach to pricing from the rest of this list. Instead of charging per minute, Microsoft sells parallel jobs with unlimited minutes: every organization gets one Microsoft-hosted job with 1,800 minutes a month and one self-hosted job for free, then pays $40 a month for each extra hosted job or $15 for each extra self-hosted job. For a team that keeps one or two pipelines busy all day, that flat rate can cost less than per-minute billing. Pipelines sits inside Azure DevOps with Repos, Boards and Artifacts, and the first five Basic users are free, then $6 per user. JetBrains' 2026 survey reports 15 percent of organizations use Azure DevOps Server, the self-hosted edition, so the figure does not cover the cloud service on its own and we score adoption with that caveat. Microsoft guarantees 99.9 percent availability for paid pipelines. We compared documented features and published prices only.

   Strengths

   • +Flat per-job pricing makes busy pipelines predictable
   • +A self-hosted parallel job costs $15 a month with unlimited minutes
   • +Microsoft guarantees at least 99.9% availability for paid Azure Pipelines

   Limitations

   • −The survey figure covers Azure DevOps Server, not the cloud service alone
   • −Hosted parallel jobs at $40 each add up for large teams
   • −Most useful inside the wider Microsoft and Azure toolchain

   SummaryAzure Pipelines is the best value for teams that run pipelines all day, thanks to flat parallel-job pricing. It fits best when the rest of the stack is already on Microsoft tools.

5. 5

   Bitbucket Pipelines

   Atlassian's CI/CD built into Bitbucket Cloud, with build minutes shared across a workspace.

   7.9overall

   Atlassian's CI/CD built into Bitbucket Cloud, with build minutes shared across a workspace.

   Best forSmall and mid-size teams that already use Jira and Bitbucket and want low-cost hosted CI.

   Adoption data

   15 millionAtlassian says 15 million developers build on Bitbucket, a figure for the whole code hosting product rather than Pipelines alone.

   Atlassian, Bitbucket (2026): “15 million developers build on Bitbucket”

   Bitbucket Pipelines is the low-cost hosted option for teams already on Atlassian tools. CI/CD is included with Bitbucket Cloud: the Free plan covers up to 5 users with 50 build minutes, Standard costs $3.65 per user per month and Premium $8, and any workspace can buy 1,000 more minutes for $10 a month, or $0.01 a minute. Minutes are measured on Atlassian cloud runners and scale with runner size, so a 5-minute step on a 2x runner counts as 10 minutes. Premium adds controls such as enforced merge checks, IP allowlisting and deployment permissions. Atlassian says 15 million developers build on Bitbucket, but that covers code hosting as a whole, and JetBrains' 2026 survey places Bitbucket Pipelines in the tier below Azure DevOps Server without a headline share, so we score adoption below the leaders. Feature depth is narrower than GitHub Actions or GitLab. We compared documented features and published prices only.

   Strengths

   • +Cheapest paid seat on this list at $3.65 per user per month
   • +Free plan for up to 5 users with unlimited private repositories
   • +Tight Jira integration for teams already on Atlassian

   Limitations

   • −Free plan includes only 50 build minutes
   • −Larger runners multiply minute usage, so a 2x runner counts double
   • −The adoption figure covers Bitbucket overall, not Pipelines

   SummaryBitbucket Pipelines is the cheapest way to add hosted CI for a Jira and Bitbucket team. Buy extra minutes early, since the free allowance is small.

6. 6

   CircleCI

   A usage-based CI/CD service that bills credits for compute, users and premium features, in the cloud or on your own servers.

   7.8overall

   A usage-based CI/CD service that bills credits for compute, users and premium features, in the cloud or on your own servers.

   Best forTeams that want a dedicated hosted CI service with a large free allowance and many machine types.

   CircleCI is a dedicated CI/CD service rather than a feature of a code host, and it supports GitHub, GitLab and Bitbucket. Its Free plan is the most generous hosted allowance here: up to 6,000 build minutes a month on a small Docker resource class, 5 active users and 30x concurrency, with Docker, Windows, Linux, Arm, macOS and self-hosted runners all available. Paid use runs on credits. Performance starts at $15 a month with 30,000 credits included, extra credits cost $15 per 25,000, and each user beyond five costs $15 a month. Bulk purchases start at 1 million credits for $600, with discounts from 5 million credits for $3,000. Credit pricing is flexible but harder to compare with a plain per-minute rate. CircleCI does not publish a customer count or survey share we could cite, and JetBrains' 2026 report does not give it a headline figure, so we score its adoption conservatively. We compared documented features and published prices only.

   Strengths

   • +Largest free hosted allowance on this list, at up to 6,000 build minutes
   • +Wide choice of machine types, including macOS and Arm
   • +Bulk credit discounts start at 5 million credits for $3,000

   Limitations

   • −Credit pricing takes work to translate into a cost per minute
   • −Each extra active user costs $15 a month on Performance
   • −No citable survey share or customer count, so adoption is scored conservatively

   SummaryCircleCI suits teams that want a code-host-neutral CI service with a big free tier. Model your credit use before moving large workloads.

7. 7

   Buildkite

   A CI/CD platform that orchestrates pipelines on your own agents or Buildkite hosted agents, built for large scale.

   7.7overall

   A CI/CD platform that orchestrates pipelines on your own agents or Buildkite hosted agents, built for large scale.

   Best forLarge engineering organizations and monorepo teams that want to run CI on their own infrastructure at high concurrency.

   Adoption data

   82.63MBuildkite reports that customers finished an average of 82.63 million CI jobs per day in October 2026, up from 19.73 million in January.

   Buildkite, About Buildkite (2026): “Jobs per day 82.63M Finished CI jobs per day, averaged by month.”

   Buildkite is built for teams with very large build volumes. It orchestrates pipelines while the work runs on your own agents or on Buildkite hosted agents, and dynamic pipelines let each build generate its own steps at runtime. Buildkite says hundreds of thousands of developers rely on it every day, and its about page reports customers finished an average of 82.63 million CI jobs a day in October 2026, up from 19.73 million in January. The Free plan covers up to 5 users, 10 concurrent jobs and 2,000 Linux vCPU minutes a month. Pro costs $30 per active user per month with 10 agents included, then $3.50 per agent, and hosted Linux agents cost $0.004 per vCPU minute, or $0.008 a minute for a 2 vCPU machine. That seat price is high for small teams, and Buildkite publishes usage rather than a survey share, so we score adoption below the survey leaders. We compared documented features and published prices only.

   Strengths

   • +Built for very high concurrency on your own infrastructure
   • +Published per-vCPU rates for hosted Linux and Mac agents
   • +30-day all-access trial with no credit card

   Limitations

   • −Pro costs $30 per active user per month, plus $3.50 per agent beyond 10
   • −Free plan is limited to 5 users and 10 concurrent jobs
   • −Adoption figure is a usage count from the vendor, not a survey share

   SummaryBuildkite is the pick for large organizations that need CI to keep up with huge monorepos on their own hardware. Smaller teams will find the $30 seat hard to justify.

8. 8

   TeamCity

   JetBrains' CI/CD server, sold as a free or licensed on-premises edition and as a managed cloud service.

   7.7overall

   JetBrains' CI/CD server, sold as a free or licensed on-premises edition and as a managed cloud service.

   Best forJVM, .NET and game development teams that want a polished self-hosted CI server or a managed JetBrains cloud.

   Adoption data

   10%In JetBrains' State of CI/CD 2026 survey, 10% of developers said their organization uses TeamCity. JetBrains makes TeamCity and ran the survey.

   JetBrains, The State of CI/CD 2026 (2026): “TeamCity is used in 10% of respondents' organizations.”

   TeamCity is JetBrains' CI/CD server, and it comes in two shapes. The On-Premises Professional edition is free forever with unlimited users, 3 build agents and 100 build configurations, while the Enterprise edition removes the configuration limit and adds standard support, with more agents sold per agent per year. TeamCity Cloud is fully managed by JetBrains and priced per committer, with build credits, 120 GB of storage and data transfer included, and a 14-day trial. Teams can also run a hybrid setup, with the server on premises and agents in the cloud or the other way round. JetBrains' 2026 survey says 10 percent of organizations use TeamCity, up from 7 percent, but JetBrains sells TeamCity and runs the survey, so we score adoption cautiously. Prices on the buy page appear in euros from our location, so we mark the USD price as pending. We compared documented features only.

   Strengths

   • +Free self-hosted Professional server with unlimited users
   • +Usage rose from 7% to 10% of organizations in JetBrains' survey
   • +Choice of on-premises, cloud or hybrid deployment

   Limitations

   • −Prices show in EUR from our location, so the USD check is pending
   • −The survey is run by TeamCity's own vendor
   • −Free edition limits build agents to 3

   SummaryTeamCity is a strong self-hosted choice, and its free edition is enough for small teams. Confirm US pricing for Cloud and Enterprise before you commit.

9. 9

   Harness CI

   The continuous integration module of Harness's software delivery platform, sold alone or in bundles through sales.

   7.3overall

   The continuous integration module of Harness's software delivery platform, sold alone or in bundles through sales.

   Best forEnterprises that want CI, CD, infrastructure as code and security testing from one platform with governance controls.

   Adoption data

   1,000+Harness says it has more than 1,000 enterprise customers, a company-wide figure that covers all of its products, not CI alone.

   Harness, About Harness (2026): “1,000+ Enterprise customers”

   Harness CI is one module of a broader software delivery platform that also covers continuous delivery, GitOps, infrastructure as code, feature management and security testing. There is a free plan for individual developers and small teams that includes Harness Open Source, and two paid tiers. DevOps Essentials bundles CI, CD, a code repository, security test orchestration and infrastructure as code for up to 500 users, with up to 60 concurrent pipeline executions and 60 self-hosted runners. Enterprise lets buyers pick modules and removes those limits. Neither paid plan has a public price, so we mark pricing as pending and score value lower than tools with published rates. Harness says it has more than 1,000 enterprise customers, but that figure covers all of its products, so adoption is scored conservatively. Essentials cannot be deployed on premises. We compared documented features only.

   Strengths

   • +CI, CD and security testing in one governed platform
   • +Enterprise plan lets buyers pick only the modules they need
   • +Free plan for individuals and small teams

   Limitations

   • −No published prices for paid plans
   • −DevOps Essentials cannot be deployed on premises
   • −The customer count covers the whole company, not CI

   SummaryHarness CI fits enterprises buying a full delivery platform with policy controls. Teams that only need CI will get clearer pricing elsewhere.
