Create free account at app.harness.io without credit card requirement — includes CI/CD for up to 5 services, feature flags for 25K MAUs, and basic cloud cost visibility Install Harness Delegate in your Kubernetes cluster or VM environment as lightweight agent for secure communication between Harness SaaS and your infrastructure Connect source code repositories and container registries using Harness Connectors, supporting GitHub, GitLab, Bitbucket, DockerHub, ECR, GCR, and ACR Link AWS, Azure, or GCP cloud accounts to Cloud Cost Management for immediate infrastructure cost visibility and savings recommendations Build canary deployment pipeline with automated rollback using existing monitoring integrations for Prometheus, Datadog, or New Relic verification
💡 Quick Start: Follow these 1 steps in order to get up and running with Harness quickly.
Explore the key features that make Harness powerful for deployment & hosting workflows.
Machine learning algorithms establish behavioral baselines for each service using metrics, logs, and traces from connected monitoring tools. During deployments, the system compares real-time data against baselines and automatically triggers rollback when anomalies exceed configured thresholds.
Direct integration with AWS, Azure, and GCP billing APIs provides real-time cost visibility, idle resource detection, right-sizing recommendations, and workload autostopping to reduce cloud spend without manual analysis.
Native canary, blue-green, and rolling deployment strategies with automated traffic shifting tied to verification results. Supports percentage-based rollouts with automatic promotion or rollback based on health metrics.
Deploy code with feature flags to production, then control exposure by user segment, percentage, or targeting rules. Supports boolean, multivariate, and JSON flags with real-time evaluation and analytics.
Built on LitmusChaos, embeds resilience testing directly into deployment pipelines. Run chaos experiments against services to validate fault tolerance before promoting releases to production traffic.
Launched in 2025-2026, provides automated root cause analysis that correlates deployment events, infrastructure changes, and monitoring data to accelerate incident resolution and reduce mean time to recovery.
Harness is a unified AI-native platform rather than a single CI engine. It combines CI/CD, feature flags, cloud cost management, chaos engineering, security testing, and an internal developer portal in one console. Its AI-powered Continuous Verification automatically detects deployment anomalies and triggers rollbacks, which standalone CI tools do not offer natively.
During and after a deployment, Harness pulls metrics, logs, and traces from connected monitoring tools like Prometheus, Datadog, or Splunk. ML algorithms compare current behavior against established baselines and flag anomalies. If deviations exceed configured thresholds, the platform automatically rolls back to the last known good version without manual intervention.
Yes, Harness offers a free tier that includes CI/CD for up to 5 services with 2,000 build minutes per month, feature flags for up to 25K monthly active users, basic cloud cost visibility for one cloud account, and community support. It is suitable for small teams evaluating the platform or running lightweight workloads. No credit card is required to sign up.
AIDA is the Harness AI Development Assistant. It generates pipeline YAML from natural language descriptions, diagnoses build and deployment failures with root cause suggestions, recommends cloud cost optimizations, and assists with policy creation. AIDA is integrated across modules to reduce manual configuration and troubleshooting time.
Harness is primarily delivered as SaaS but offers a self-managed enterprise option for organizations with strict data residency or air-gapped environment requirements. The self-managed version supports deployment on Kubernetes clusters and provides the same feature set as the SaaS offering, though it requires customer-managed infrastructure for hosting and upgrades.
Now that you know how to use Harness, it's time to put this knowledge into practice.
