Short answer: Choose E2B or Daytona if you are building an agent product and want sandboxes you control from code. Daytona is the pick if you also need Windows, macOS or GPUs. Choose Orgo if you want always-on desktops, one-click agent templates or a computer per client. Choose Simular Box if you want Claude, ChatGPT, Codex and your other agents to share one cloud computer through one MCP link, with the same files and logins.
Definition. A cloud computer for AI agents is a remote machine with a real desktop, browser, file system and shell that a model controls through screenshots, clicks, keystrokes and commands, instead of a person sitting at it.
All four products in this guide give an agent such a computer. They differ in who sets it up, how the agent reaches it, and what happens to its state between tasks.
We looked at what an agent actually needs to finish a task on a computer: a full desktop, a way to connect the agent you already use, state that survives between tasks, tools that make desktop work reliable, and a way for a person to watch and step in. We did not run a shared benchmark across the four products, so this guide does not rank them on speed or cost per task. Facts were checked against each vendor's docs and pricing pages on 6–11 November 2026. Product features change often, so check the linked sources before you commit.
| Simular Box | Orgo | E2B Desktop | Daytona | |
|---|---|---|---|---|
| What it is | One cloud computer that every agent you use shares | Always-on cloud desktops for agents | Code sandboxes with a desktop template | Sandboxes for agents, evals and training |
| Operating systems | Linux (Ubuntu desktop) | Linux; Windows on Scale or as an add-on; Mac and iPhone by request | Linux (Ubuntu + XFCE) | Linux; Windows VM on Tier 3+ on request; macOS through a partner |
| How your agent connects | One hosted MCP link with sign-in; install line for coding agents; custom connector in Claude, ChatGPT and Gemini | Hosted MCP, CLI, REST API, Python and TypeScript SDKs | Python and JS SDKs; no hosted MCP to drive a sandbox | SDKs, REST API, local MCP via the CLI |
| Several agents on one computer | Yes. Agents share one box and pick up each other's work | Marketed as one agent per computer; up to 4 screens per Linux computer | You wire each agent to a sandbox in code | You wire each agent to a sandbox in code |
| State between tasks | Keeps programs, files and logins. The Medium plan's box never sleeps; on other plans the box sleeps when idle and wakes with everything kept | Paid computers always on; daily backups kept 7 days | Pause keeps disk and memory; a run lasts at most 1 h (Hobby) or 24 h (Pro) | Persistent by default; stopping keeps the disk |
| Computer-use tools | Shell, files and browser first, screenshots last; GUI plans and scripts; saved tasks replay without model calls | Screenshot, click, type, shell commands; hosted orgo-agent model | Click, type, screenshot and window tools | Click, type, screenshot, accessibility tree, screen recording |
| Watch and take over | Live view, take control, hand back; time-limited share link | Live screens, take over, 30-minute guest links | noVNC stream, interactive by default | Browser VNC with takeover; recordings |
| Price to start | $5 free credit; from $0.10/hour; plans $19 and $39/month | $5 free credit; Starter $29/month; $0.055/hour hourly | Hobby free with one-time $100 credit; Pro $150/month + usage | Pay as you go; $200 free compute |
| Best for | Using the agents you already pay for, together, on one computer | Always-on agents, agencies, Windows or Mac desktops | Developers building agent products on SDKs | Agent infrastructure that needs many sandboxes, Windows, macOS or GPUs |

Simular Box (box by Simular) is a cloud computer that your existing agents share. It runs a Linux desktop with Chrome, files and a terminal, and every agent reaches it through one remote MCP server at https://mcp.box.simular.ai/mcp. You sign in once with OAuth; there is no key to copy unless your client cannot sign in.

Claude, ChatGPT and the Gemini app add Simular Box as a custom connector, and DeepSeek Harness uses the box plugin.Best for: developers and power users who already run Claude, ChatGPT, Codex or Cursor and want them to share one cloud computer that stays signed in.

Orgo sells cloud desktops that stay on. Each agent gets its own virtual machine with a desktop, browser and terminal. Linux is on every plan, Windows on Scale or as a paid add-on, and Mac and iPhone by request. Orgo says it is used by more than 1,000 teams (own claim).
Best for: teams that want always-on desktops, Windows or Mac machines, agencies running an agent per client, and anyone who wants a one-click Hermes or OpenClaw setup.

E2B is a sandbox platform that developers build on through SDKs. Each sandbox is a Firecracker microVM with its own kernel. The Desktop template adds an Ubuntu XFCE desktop with LibreOffice, a browser and a file manager.
Best for: developers building their own agent product who want many short-lived, isolated machines controlled from code.

Daytona runs sandboxes for agents, evals and training. It offers containers and VMs, Linux by default, Windows VMs on higher tiers on request, macOS through a partner, and GPUs from RTX 4090 to B300.

All four give the agent a full graphical desktop. Orgo has the widest OS range for a hosted desktop (Linux, Windows, Mac and iPhone). Daytona is close, adding GPUs. E2B Desktop and Simular Box run Linux only.
This is the biggest practical difference.
Only Simular Box is built around several agents sharing one computer and handing work to each other. On Orgo you can give several agents their own screens on one Linux computer. On E2B and Daytona you build the sharing yourself.
Fewer screenshots and model calls usually mean fewer steps per task.
All four let a person see the screen and take control:
Which keeps an agent's logins between sessions? Orgo's always-on computers and Daytona's persistent sandboxes keep state. E2B keeps state while paused. Simular Box keeps signed-in sessions in Chrome on the box, never sending passwords to the AI.
How much do Orgo, E2B and Daytona cost? Orgo Starter is $29/month ($23/month billed yearly) for one always-on computer, and hourly computers cost $0.055/hour. E2B and Daytona charge for usage, about $0.33/hour at 4 vCPU and 8 GB; E2B Hobby includes a one-time $100 credit and Daytona $200 of free compute. Simular Box gives $5 of free credit, then pay as you go from $0.10/hour for a 2 vCPU / 4 GB box, or plans at $19 and $39 a month.
