Sandboxes

AgentBox

Run multiple agents in parallel sandboxed VMs, with a single command, on your PC or in the cloud

agentOS

A virtual operating system for agents, with filesystem, execution, and orchestration in one lightweight library.

Amika

Run any agent in a sandbox you control, on the cloud or your own machines. Use the sandbox as a human-in-the-loop devbox, or build autonomous agentic workflows.

Box by ASCII

The cheapest, most powerful sandboxes for building profitable long-running agents as a service. Persistent Linux VMs with SSH, Docker inside, and IPv4 per machine. One command: `box new`. $20 = 555 hours of 4 vCPU / 8 GB. Bring any agent: Claude Code, Codex, OpenCode. Cheaper than E2B, Codespaces, or Daytona.

Cloudflare Computer

Give your agent a computer 👾

Daytona

Secure Infrastructure for Running AI-Generated Code. Sub 90ms sandbox creation from code to execution.

hotcell

Self-hostable sandbox SDK inspired by Cloudflare Sandbox SDK. works on any device

hypeman

A multi-hypervisor VM runtime for OCI images, supporting Cloud Hypervisor, Firecracker, QEMU, and Apple Virtualization.framework.

Prime Intellect

Train, deploy, and continuously improve your own models on an integrated compute, training, inference, and sandbox stack.

Orchestrate sandboxed coding agents in TypeScript with sandcastle.run()

Sandlock

The lightest AI sandbox. A process-based sandbox for Linux, no container, no VM, no privilege, no prompt injection

Sprites

Sprites are stateful sandbox environments with checkpoint & restore. A hardware-isolated Linux computer for arbitrary code — the simplest answer for 'where should I run a blob of code'.
