Agent Substrate: the core system

★ 2.8K371 forksGoApache-2.0agent-substrate

Agent Substrate is a Go/Kubernetes runtime for high-density agent execution: it multiplexes stateful agent actors onto a small worker pool with sub-500ms suspend/resume, zero-trust kernel and network isolation, and support for microVM/gVisor sandboxes plus ADK, LangChain, MCP and coding agents.

Use Cases

Running millions of high-density agent sandboxesSub-second suspend/resume of stateful agentsPersisting filesystem and memory state across agent sessionsSandboxing MCP servers as durable toolsHosting high-density stateful coding agent sessions (Claude Code, Codex)Zero-trust multi-tenant agent isolationRL rollout infrastructure spanning agent, inference and trainingRouting traffic to idle-on-demand agentsDeploying gVisor or microVM isolated workloads on KubernetesOversubscribing physical pods 30x for agent workloads
