Use Cases & Benefits
- Provides a lightweight in-process operating system for AI agents using WebAssembly and V8 isolates.
- Enables near-instant agent startup with minimal memory and cost, avoiding full VM or container overhead.
- Use for embedding AI agents directly into backend services with secure, deny-by-default permissions.
- Use for orchestrating multi-agent workflows with real-time collaboration and agent-to-agent delegation.
- Use for running isolated Node.js and shell scripts inside a sandboxed environment without network hops.

General guidance from repository metadata, not legal advice. How we score
From the README
A portable open-source operating system for AI agents. Near-zero cold starts (~6 ms), up to 32x cheaper than sandboxes. Powered by WebAssembly and V8 isolates.
Supports Pi, Claude Code*, Codex*, Amp*, and OpenCode*
agentOS is a lightweight VM that runs inside your process. Sandboxes are full Linux environments. agentOS integrates agents into your backend with host tools and granular permissions. Sandboxes give you a full OS for browsers, native binaries, and dev servers.
You don't have to choose: agentOS works with sandboxes through the sandbox extension, spinning up a full sandbox on demand and mounting the sandbox's file system when the workload needs it.
