AX – Google’s Open Agentic Orchestrator

Google’s AX is an open, Kubernetes-native runtime for running agents as durable, resumable tasks with policy-controlled execution, auditing, and observability.

The runtime is deliberately below the model and harness layer: it provides scheduling, recovery, coordination, resource limits, network egress allowlists, and protocol support for MCP and A2A while letting users bring their own model and planning logic. The trade-off is substantial operational weight—the quickstart requires Kubernetes, a registry, and the Agent Substrate control plane—and the project is early enough that its long-term scope and support are uncertain.

HN’s 545-point, 245-comment discussion split between people interested in secure, scalable multi-agent workloads and criticism that this is “Kubernetes for agents,” overbuilt for local development, and hard to evaluate without clearer benchmarks. Several commenters highlighted the distinction between the infra-layer runtime and application-layer workflow frameworks, plus the importance of gVisor/microVM isolation, resumability, and zero-trust permissions.
