Significantly lower cost and memory footprint than traditional sandboxes.

Granular security with V8 isolates and deny-by-default permissions.

Embeddable in backend processes, enabling direct function calls without network overhead.

Supports multiple AI agents (Pi, Claude Code, etc.) with unified API and automatic persistence.

Quick Start

npm install @rivet-dev/agent-os @rivet-dev/agent-os-common @rivet-dev/agent-os-pi

Detailed Introduction

agentOS is an innovative open-source operating system specifically designed for AI agents, leveraging WebAssembly and V8 isolates to deliver unparalleled performance and cost efficiency. Unlike traditional heavy sandboxes, agentOS runs directly within your process, eliminating cold start delays (as low as ~6 ms) and drastically reducing memory consumption by up to 47x. It provides a secure, isolated environment with granular, deny-by-default permissions, allowing agents to interact with your backend functions directly without network hops. This portability and efficiency make it ideal for deploying AI agents across various platforms, from local development to cloud environments, offering a significantly faster and cheaper alternative for agent execution.
