- Built-in policy-as-code and governance
- Feature flag management and progressive delivery
- Cost optimization and auto-stopping idle infrastructure
Why Choose Harness:
- Focuses on reliability, automation, and cost efficiency
- Offers a highly governed CI/CD pipeline model
- Scales well in enterprise and hybrid cloud environments
4. Garden
Best for: Kubernetes development workflows and fast inner-loop automation.
Garden helps streamline development, testing, and deployment for Kubernetes-based applications. It enables fast feedback loops with caching, hot reloading, and dev/test environment automation.
Key Features:
- Developer-first CLI for building, testing, and deploying microservices
- Automates dev/test workflows across Kubernetes clusters
- Task orchestration, logs, hot reloading
