10 Best CI/CD Tools of 2026

GitHub Actions ranks first because it removes the integration step that every other CI tool needs: workflows live in the repository and trigger on pushes, pull requests, issues and schedules. The Free plan includes 2,000 minutes a month for private repositories, Team adds 3,000 minutes at $4 per user per month, and Enterprise includes 50,000 minutes at $21 per user per month. Standard hosted runners are free for public repositories. Hosted runners cover Linux, macOS, Windows, ARM, GPU and containers, matrix builds test several versions in parallel, and secrets can be scoped to a repository, environment or organization. Usage past the allowance is billed per minute, with GitHub documenting $0.006 per minute for a 2-core Linux runner and $0.010 for 2-core Windows. The limits are clear: it only builds code hosted on GitHub, and teams with heavy macOS or long integration suites should model their minutes before they commit, since those costs climb faster than seat prices.

CircleCI is the most flexible standalone CI service on this list. The Free plan gives up to 6,000 build minutes on a small Docker resource class, up to 5 active users and 30x concurrency across Docker, Windows, Linux, Arm, macOS and self-hosted runners. The Performance plan starts at $15 per month, includes 30,000 free credits, raises concurrency to 80x and sells more credits at $15 per 25,000, with paid credits rolling over for up to a year. Bulk purchases start at 1 million credits for $600. Orbs package common configuration so teams can reuse deployment steps, and the docs include migration guides from Jenkins, GitHub Actions, GitLab and Travis CI. The trade-off is forecasting: machine size, users, network, storage and Docker layer caching all draw on the same credit balance, so a growing team needs to watch usage. GPU machines and the largest classes sit on the annual Scale plan.

GitLab CI/CD is the strongest choice for teams that want one platform rather than a chain of tools. Pipelines live in a .gitlab-ci.yml file at the root of the project, where stages set the order and jobs hold the scripts, and GitLab creates a pipeline on commits, merge requests, schedules or manual runs. Runners can be GitLab-hosted or your own machines, and jobs can run inside a container image you name. The Free tier covers 5 users per top-level group with 400 compute minutes and 10 GiB of storage, and already includes static application security testing. Premium costs $29 per user per month billed annually and raises compute to 10,000 minutes with 500 GiB of storage, plus $12 of GitLab Credits per user for AI features. Ultimate adds application security testing and 50,000 minutes at a custom price. The drawback is the jump from free to $29 per seat, which is steep for teams that only need pipelines.

Azure Pipelines prices capacity differently from most CI tools: instead of metering minutes, you buy parallel jobs. Every organization gets 1 Microsoft-hosted parallel job with 1,800 minutes a month and 1 self-hosted parallel job with unlimited minutes. Each additional Microsoft-hosted job costs $40 per month with unlimited minutes, and each extra self-hosted job costs $15. That model is easy to budget for a team that runs builds all day, since a busy agent costs the same as an idle one. Hosted agents cover Linux, macOS and Windows, and pipelines can build web, desktop and mobile apps and deploy to any cloud or on premises. It sits inside Azure DevOps, where the first 5 Basic users are free and more cost $6 per user per month. The downside is complexity: Azure DevOps has many services and settings, and teams on GitHub may find GitHub Actions simpler for the same work.

Buildkite is built for teams whose CI load has outgrown shared hosted runners. Pipelines run on agents you connect, with no limit on parallel builds, or on Buildkite hosted agents billed per vCPU minute at $0.004 on Linux and $0.02 on Mac, metered to the second. Dynamic pipelines can generate their own steps at runtime, which helps large monorepos build only what changed. The Free plan covers up to 5 active users, up to 10 concurrent jobs and up to 2,000 Linux vCPU minutes. Pro costs $30 per active user per month, supports up to 50 users, includes 10 self-hosted agents and charges $3.50 per extra agent, and includes 1 million test executions a month for flaky test detection. The weaknesses are price and effort: it is the most expensive seat here, and running your own agent fleet takes engineering time. For smaller teams the free plan or a built-in CI is usually enough.

Bitbucket Pipelines is the low-cost choice for teams that already use Jira. It is built into Bitbucket Cloud, so there are no plugins to install, and deployments link back to Jira tickets so product managers can see what shipped. Pipelines can run on Atlassian's hosted runners or on your own runners behind a firewall, and Atlassian says builds work with any language and on Linux, Windows and macOS for x86 and ARM. Pipes provide ready-made integrations, and workflows can change at runtime based on code changes. The Free plan covers up to 5 users with 50 build minutes to get started. Standard costs $3.65 per user per month and Premium $8, and extra capacity costs $10 for 1,000 minutes. Note that a step on a 2x runner counts double, so larger machines drain the allowance faster. Teams outside the Atlassian ecosystem get less from it than from the CI built into their own Git host.

Semaphore is the simplest pricing model here: there are no per-seat fees, every organization gets $15 of free usage each month, and after that you pay per minute for the machines you use. Ubuntu x64 costs $0.0075 per minute on 2 vCPU, Ubuntu ARM $0.003, macOS $0.09 on 4 vCPU, and self-hosted agents $0.0025 per minute on any machine. Artifacts are free up to 20 GB of egress and 100 GB of storage a month, each project gets 9.6 GB of cache, and 20 concurrent jobs are included by default. Semaphore also offers an open source Community Edition, monorepo support, test reports and an MCP server that lets coding agents configure and run pipelines. The catch is that support is unbundled: free support covers setup and Git integration, while advanced troubleshooting starts with a Basic plan at $50 a month. Its integration catalog is also smaller than the big platforms.

Jenkins is the free option on this list and still the most extensible. It is a self-contained Java program with packages for Windows, Linux, macOS and other Unix-like systems, configured through a web interface with on-the-fly error checks. More than 2,300 community plugins connect it to practically every tool in the CI/CD toolchain, and builds can be spread across multiple machines to run tests and deployments in parallel. Because the software costs nothing, it scores well on value, and it works in places hosted CI cannot reach, such as air-gapped networks. The real cost is people: someone has to provision the controller and agents, apply security updates, back up configuration and test plugin upgrades. That is why its ease of use score is the lowest here. Teams without that capacity usually spend less overall on a hosted service, even after minute charges.

TeamCity is the polished alternative to Jenkins for teams that want to run CI on their own servers. The on-premises Professional edition is free forever with unlimited users, 3 build agents and up to 100 build configurations, and the Enterprise edition removes the configuration limit and adds standard support. Extra build agents can be bought for more parallel builds on either server. If you would rather not run servers, TeamCity Cloud is hosted by JetBrains, priced per committer with a minimum of 3, and includes build credits, storage and data transfer, with a 14-day free trial. JetBrains lists configuration as code, test automation, metrics and security among its features. We could only see TeamCity prices in euros from our location, so we have not quoted a USD price here; check the buy page for your currency. Its main limit is the free edition's cap of 100 build configurations, which larger organizations reach quickly.

Harness approaches CI as one part of a full delivery platform. Its CI module includes Build Intelligence, which caches unchanged compilation outputs, one-click Docker layer caching for Maven, npm, Gradle and pip, and Test Intelligence, which runs only the tests that matter for a change and quarantines flaky tests. Harness Cloud provides managed Mac, Linux and Windows build machines, and templates plus OPA policies let platform teams enforce standards on every build. AI features draft pipelines and analyze failed builds. The Free plan includes Harness Open Source and community support. The Essentials plan bundles continuous delivery and GitOps, CI, infrastructure as code management and security testing orchestration, and Enterprise lets you choose modules, but both are priced through sales. That lack of published prices, plus the breadth of the platform, is why Harness scores lowest on value here. It makes most sense for organizations standardizing delivery across many teams.
