what it is

Sandboxer gives AI agents and developers their own cloud Linux machine: a full Ubuntu 24.04 microVM with root, Docker and nested KVM, coding agents (Claude Code, Codex, OpenCode) preinstalled, an HTTPS URL for any port, and stop/resume that keeps running processes in memory. Drive it from a CLI, REST API, TypeScript and Python SDKs, or a hosted MCP server at sandboxer.com/mcp. Billed per second while running; nothing while paused. Not to be confused with the 'Sandboxer' Windows Sandbox app in the Microsoft Store.
