Simular Launches box, a Shared Cloud Computer That ChatGPT, Claude, Codex and Other Agents Can Operate
2,000,000,000 PCs sit on people's desks today. The next billion computers? They’ll be autonomous computers, driven by agents. Introducing box by @Simular: one computer for ChatGPT, Claude, Codex, Gemini, DeepSeek and all your other agents. With box, agents open apps, run the terminal, fill in forms, and stay signed in for whatever tasks come next.
Context
Agents from different companies can share one persistent desktop with logins and files, so work started in one assistant can be finished in another.
Simular builds computer use agents. Its new product, box, gives AI assistants a cloud Linux desktop they connect to as a remote MCP server. The launch post passed 1.7 million views.
Deep dive
Simular posted on November 12 that it is launching box, which it calls one computer for ChatGPT, Claude, Codex, Gemini, DeepSeek and other agents. The post says agents using box can open apps, run the terminal, fill in forms and stay signed in for later tasks.
Simular's announcement describes box as a cloud computer built for agents doing computer tasks. It says users can add box to chat apps like Claude, ChatGPT or Gemini, give always on agents such as OpenClaw, Hermes or Claude Code a shared machine, or use it with coding agents like Codex and Cursor. Logins, files and apps live on the box, so one agent can start a job and another can finish it.
The company claims its agent reaches state of the art performance on the OSWorld benchmark with the best cost efficiency, and says box is 10x faster and cheaper, a figure from Simular that has not been independently checked. The product page says box runs as a hosted MCP server, that each account gets one cloud Linux desktop that sleeps when idle, and that the box itself is free while model calls use account credits.
What to expect next
Watch for independent tests of Simular's OSWorld and cost claims, and for how box handles security when many agents share one signed in machine. Support for Windows, macOS and Android, which Simular has said will come later, would widen its use. Rivals offering cloud desktops for agents are likely to respond on price and persistence. Pricing for heavy users is another detail to watch.
