Google announced on November 5, 2026, that it would donate Agent Substrate, gVisor and OpenRL to the Cloud Native Computing Foundation (CNCF). Google said the three projects had entered the CNCF Sandbox the previous month. Alongside the donation, Agent Substrate reached version 1.0 and became generally available on Google Kubernetes Engine (GKE). 5
The projects point toward a common goal: open-source infrastructure for running AI agents and their workloads in isolated environments. The announcement confirms their donation, but the available sources do not establish that they form a single integrated stack or spell out OpenRL’s technical role.
How Agent Substrate handles idle agents
Agent Substrate adds an actor-based control and data plane on top of Kubernetes. Its design separates an agent session, called an Actor, from the sandbox compute it uses. GKE documentation describes a Worker as a sandbox where an active Actor runs. 1

When an agent is suspended, the system snapshots its active memory and local files. When it needs to run again, its state is restored onto an available sandbox. Google’s GKE documentation says restoration takes less than a second; Google’s product announcement separately claims resume operations below 500 milliseconds. 1

Google also advertises a target of 10 times the density of standard container runtimes and more than 500 suspend-and-resume activations per second. These are Google’s published performance claims, not independent benchmark results. The architecture documentation also cautions that much of its described architecture is aspirational and not yet implemented, so the claims should not be read as confirmation that every planned capability is present in version 1.0. 2

Where gVisor fits—and what OpenRL adds
Agent Substrate can use gVisor or Cloud Hypervisor to run workloads in sandboxes that isolate application code from the host kernel, according to the GKE documentation. 1 Google’s announcement also identifies gVisor’s
runsc as an open-source application kernel. 4 Together, the sources support gVisor’s role as an isolation option for workloads managed through Agent Substrate; they do not provide a full technical account of its isolation mechanism or a list of its users.
OpenRL is part of the donation, but the available announcement excerpts do not explain how it works or how it might connect technically to Agent Substrate or gVisor. It would therefore be premature to describe the three projects as a complete, tightly integrated agent platform based on these sources alone. 5
What the CNCF donation establishes
The announcement gives all three projects a shared CNCF home after their Sandbox acceptance. That is a meaningful move toward community stewardship, but a donation by itself does not prove how future governance will work or guarantee equal influence among contributors. Google describes the projects as open source and says they originated at Google; the available excerpts do not substantiate specific maintainer changes or the governance arrangements raised in broader discussion. 5
CNCF lists Agent Substrate at the Sandbox maturity level. Its project page reports 851 total contributors, but that figure does not establish a contributor count for the November 5 announcement or a breakdown by employer. 29
The main practical takeaway is clearer than the governance details: Agent Substrate 1.0 is available on GKE, and Google presents it as a way to run isolated agent workloads while returning compute to a pool when agents are idle. Its performance figures are vendor claims, and the supplied sources do not verify the more specific claim that a particular October 20 event marked its approval. 1

8 The CNCF lists KubeCon + CloudNativeCon North America for November 9–12 in Salt Lake City, but the available sources do not specify Google’s planned demonstrations or sessions.
