CAST AI
AI-driven Kubernetes cost and performance automation Category: Coding & Development.
- Large automatic Kubernetes cost reductions
- Broad multi-cloud and integration coverage
- Low-risk read-only evaluation before automation
- Automatic workload rightsizing from real usage
- Specialized only to Kubernetes environments
- Full automation requires trusting an external platform
- Results still need a quick human review for best quality
env0
env0 is an infrastructure-as-code management and governance platform: self-service templates with RBAC and policy-as-code guardrails, drift detection and remediation, cloud asset management, and a newer AI-era control plane that unifies declared and discovered cloud state.
- Governs fast deployment with guardrails
- Keeps code and cloud in sync via drift control
- Connects existing repos without code changes
- Consistent policy across teams and clouds
- Oversized for small, simple setups
- Autonomous control plane partly early access
- Value tied to having meaningful IaC
