Sandboxer vs Google Agent Platform Sandboxes

Google's Gemini Enterprise Agent Platform offers managed sandboxes for code execution, browser-based computer use, shell and custom containers, with TTLs of 7 to 14 days and idle pause/resume. They use container sandboxing inside Google Cloud governance (VPC Service Controls, CMEK). Pick Google if you are already on Google Cloud and need those controls.

Google ties sandboxes to Google Cloud projects and the Agent Platform; Sandboxer is a standalone API, CLI and SDKs.

Pick Sandboxer if

Each Sandboxer sandbox is a full Ubuntu 24.04 VM with its own kernel, root/sudo, systemd and Docker preinstalled.
Stopping saves memory and disk and resume brings running processes back; stopped sandboxes cost nothing.
Coding agents (Claude Code, Codex, OpenCode and others) are preinstalled and driven through a prompt API, with an MCP server, REST API, CLI and TypeScript and Python SDKs.
