Agent-Sandbox vs zeroboot
AI-agent code sandboxes compared
Agent-Sandbox and zeroboot both isolate code generated by AI agents. Agent-Sandbox provides a Kubernetes-based platform with REST and MCP interfaces, while zeroboot creates code-execution sandboxes by forking Firecracker VM snapshots.

Agent-Sandbox: Kubernetes Sandboxes for AI Agents
Agent-Sandbox wraps the Kubernetes-based AIO Sandbox foundation in a REST API and MCP server for running untrusted agent code and browser or computer tasks. It is self-hosted and E2B-compatible, aimed at teams that want sandbox management without working directly with kubectl.

zeroboot: Create Fast VM Sandboxes for AI Agents
Zeroboot uses copy-on-write forks of Firecracker VM snapshots to create isolated sandboxes quickly for code execution. It is aimed at teams running agent-generated code that need VM-level isolation and can accept a working-prototype maturity level.

Key differences
- Agent-Sandbox covers code, browser, and computer-use sandboxes; zeroboot focuses on isolated code execution.
- Agent-Sandbox runs on a compatible Kubernetes cluster; self-hosted zeroboot requires Linux with KVM, and it also offers a managed API.
- Agent-Sandbox is written in Go, while zeroboot is written in Rust; both use the Apache-2.0 license.
- Agent-Sandbox offers a REST API, MCP server, and built-in UI; zeroboot provides an HTTP API and Python and TypeScript SDKs.
- Agent-Sandbox includes lifecycle options such as pause and resume, snapshots, and sandbox pools; zeroboot forks instances from prepared VM snapshots using copy-on-write memory.
- Zeroboot is described as a working prototype, while Agent-Sandbox lists operational considerations including limited recent issue closure activity and no reported test suite in its requirements metadata.
Choose Agent-Sandbox if you…
- need managed sandbox lifecycle for code, browser, or computer-use tasks on Kubernetes.
- want REST and MCP interfaces, a built-in UI, or E2B compatibility.
- need per-agent or per-user isolation and options such as sandbox pools or pause and resume.
Choose zeroboot if you…
- need VM-based isolation for code execution and can provide Linux hosts with KVM when self-hosting.
- want to create execution environments by forking prepared Firecracker VM snapshots.
- prefer an HTTP API with Python or TypeScript SDKs, or want to try a managed code-execution API.
