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

KERNEL is a cloud browser infrastructure platform for developers building AI agents and browser-based automation. It provides managed browser sessions that agents can use to navigate websites, interact with page content, and perform tasks through code rather than relying on a local browser setup. The service is designed for production workloads, with persistent browser profiles, live browser viewing, session recording and replay, and controls for managing browser access. Teams can connect agent workflows through KERNEL's APIs, SDKs, and hosted MCP server, and use the platform for web research, data gathering, and other tasks that require interacting with websites. Plans for individual developers, startups, and enterprise teams include different browser concurrency, usage credits, and access to capabilities such as managed authentication, stealth mode, and regional browsers.
