agentOS reimagines how AI coding agents are deployed by replacing heavy sandbox environments with lightweight WebAssembly and V8 isolates that run directly inside your application process. Traditional agent sandboxes spin up full containers or VMs, adding seconds of cold-start latency and significant compute cost. agentOS achieves approximately six-millisecond cold starts while being roughly thirty-two times cheaper, using the same isolation technology that powers Google Chrome's security model.
The system integrates agents into existing backend infrastructure through a host-tools architecture where the host application controls what each agent can access. File systems, databases, S3 buckets, and GitHub repositories are exposed through scoped permissions rather than per-agent credentials, maintaining security without complex credential management. Agents like Claude Code get full tool access including file editing and shell execution, while the host retains granular control over resource boundaries and access policies.
Distributed as a standard npm package, agentOS requires no specialized infrastructure, orchestration layers, or vendor lock-in. It runs anywhere Node.js runs, from local development machines to cloud servers, with the same consistent behavior. The open-source Apache 2.0 license and growing registry of supported agents and tools make it a practical choice for teams that need to embed autonomous coding agents into their platforms while keeping operational costs low and startup times nearly instantaneous.
