About
Agent Substrate is an open-source runtime for operating isolated, stateful agent and code-execution sandboxes on Kubernetes. It coordinates actor and worker lifecycles, places active workloads on a shared pool of ready capacity, and can suspend idle environments while preserving memory and filesystem state for later resumption. Sandboxes use gVisor or Cloud Hypervisor microVM isolation, with per-actor identity and network controls. Agent Substrate is designed for platform and infrastructure teams building agent-hosting services, coding environments, and other workloads that execute untrusted or intermittent tasks. The core project is Kubernetes-portable; Google Cloud also provides GKE-optimized deployment tooling. Optional Filestore agent volumes can persist workspaces across suspend and resume cycles.

About
Phinite provides shared infrastructure for building, deploying, and governing AI agents across orchestration, security, observability, lifecycle management, and environment promotion — so engineering teams don't rebuild these layers for every new agent use case.
Core capabilities:
Orchestration for multi-agent systems (agent-to-agent, nested calls)
Deep session-level observability: execution timelines, decision variables, tool calls, latency/cost tracking
Private Agent Registry for skill discoverability
Eval suite for accuracy/safety benchmarking
Dev-to-Production workflow with environment promotion
Kubernetes-native deployment, VPC-internal deployability
SOC 2 Type 2 compliance
