Why teams switch

CI built for how AI teams ship

Why teams choose Harness Software Delivery Agent for continuous integration and builds.

Speed of Builds

AI writes code faster than legacy CI can build it

Build Intelligence, Docker Layer Caching, and Harness Cloud cut build time at every layer.

Fast and Reliable Tests

Full test suites, regressions, and flaky tests block every PR

Test Intelligence runs only what matters, flaky tests are quarantined automatically, and coverage gates catch regressions.

Governance

1,000 pipelines, 1,000 different standards. AI isn't governed

Golden templates + OPA policies enforced at every build. AI is governed

Harness CI

Fast, scalable, and safe builds

Move fast. Stay compliant. Every build, every time.

Pipeline AI

Build fast. Debug instantly.

Harness Software Delivery Agent is powered by a Knowledge Graph across your continuous integration pipelines, test history, and code changes. AI that acts on context, not guesses.

Pipeline Authoring. Describe your stack. Get a production-ready pipeline with caching, tests, and security scanning already configured.

Error Analyzer. Build breaks? AI cross-references your commits, deps, and test history to pinpoint root cause in seconds.

Worker Agents for CI. Autonomous pipeline agents (such as Code Review, Autofix) that execute specialized software delivery tasks within governed workflows.

Build Insights. Track build minutes and compute waste across every team. AI surfaces what to fix and where credits go.

Use AI where necessary
Speed of Builds

CI built for the code volume AI generates

AI writes code faster than legacy CI can build and test it. Close that gap at every layer of the build.

Build Intelligence. Incremental builds cache unchanged compilation outputs. If a module didn't change, it doesn't rebuild.

Docker Layer Caching. 1-click caching for Docker layers and package manager dependencies: Maven, npm, Gradle, pip, and more. No YAML required.

Harness Cloud. Fully managed, isolated build machines for Mac, Linux, and Windows. No noisy neighbors. No infrastructure to maintain.

Speed up your builds
Fast and Reliable Tests

Faster CI feedback, without losing signal

Fast builds mean nothing if you're waiting on tests. Get faster feedback without cutting corners.

Test Intelligence. AI analyzes your codebase and selects only the tests impacted by a code change.

Flaky Test Detection and Quarantine. Automatically detects and quarantines non-deterministic tests.

Code coverage. Set a coverage threshold. If a PR drops below it, the pipeline blocks.

Make your tests fast and reliable
Built for every role

Works for your whole team

Build the fastest path to production

Golden pipeline templates teams actually adopt: no drift, no guesswork

Enforce standards with OPA policies, not tribal knowledge

Builds and tests run as fast as possible, unblocking the CI bottleneck

Customer Success

Engineering teams ship faster with Harness CI

22 min → under 5 min
Prior to Harness, a CI pipeline build for an airport operation application took nearly 22 minutes. Now, it's done in under 5 minutes for the exact same code.

5x faster builds
50 templates replaced 36,000 scripted pipelines. Builds went from hours to minutes. If another Log4j hit, we could respond in minutes - not weeks.

40% faster builds
We achieved 40% faster builds and 90% faster deployments using Harness CI/CD.

Integrations

Connects to your stack on day one

Harness CI plugs into your SCM, build tools, test frameworks, artifact registries, cloud providers, and observability stack: no rip-and-replace.

Frequently asked questions

Harness CI is a continuous integration platform that securely accelerates build and test execution times by almost 8x. It uses AI-powered features, including organization-specific pipeline generation, build troubleshooting, and Test Intelligence, along with Docker Layer Caching and hyper-optimized infrastructure to help teams build and test code faster. The Harness Code Repository (Git-based SCM) comes free as part of Harness CI.

Harness's Build Intelligence and Docker Layer Caching features use smart caching at every step of the build process, caching build outputs from Gradle, Bazel, and Maven, as well as Docker layers and package manager dependencies. This significantly reduces build times and improves efficiency.

Test Intelligence uses AI to identify and run only the tests that matter based on your code changes, accelerating test cycles by up to 80% and significantly reducing developer wait time.

Harness Cloud is Harness's hosted build infrastructure. It provides lightning-fast builds on optimized virtual machines while ensuring tamper-proof, SLSA Level 3-compliant builds through robust security features: no infrastructure to manage on your end.

Yes. Harness CI supports first-class integrations with GitHub Actions, Bitrise Workflow Steps, Drone Plugins, and all major git-based SCM providers.

Yes. Harness provides a Migration Utility (https://harness.io/jenkins) that automates the conversion of pipelines from Jenkins, GitHub Actions, CircleCI, and other CI systems into Harness CI. It translates your existing pipeline definitions, preserving stages, steps, and environment variables, so teams can migrate without rewriting everything from scratch. For complex pipelines, the AI-powered authoring in Pipeline AI can generate an equivalent Harness pipeline from a plain-language description of your stack.
