AgentOS SDK

AgentOS SDK: Virtual operating system library providing files, processes, shell, and networking for AI agents.

AgentOS SDK is a virtual operating system library designed to give AI agents their own files, processes, shell, and networking. It runs as a single package utilizing WebAssembly and V8 isolates instead of relying on a separate microVM fleet. The system provides Linux-compatible POSIX files, process management, and networking with direct function calls and scoped host function access. It targets developers building AI agents and agent frameworks who need lightweight isolation and fast cold starts. Supported software and packages include Node.js, Python, Bash, SQLite3, DuckDB, curl, and git, with persistent POSIX filesystem mounting for S3, Google Drive, or host directories.
