The briefing
Simular Box is a cloud Ubuntu desktop for your AI. Add it as a remote MCP server in Claude, ChatGPT, Claude Code, Codex, Cursor and similar apps so the agent can browse, type and run commands in the cloud while your own machine stays free.
What you get
- The cloud Linux desktop itself is free—one box per account. It sleeps when idle and wakes when your AI connects.
- The free tier includes 1,000 credits per day, resetting at UTC midnight. The machine is free; credits mainly cover model calls inside the box. If you drive it with your own agent, model spend stays on your own account.
- Free tier also includes scheduled wake-ups, file restore and Flows. Typical free specs are about 4 CPUs, 8 GB RAM and 40 GB disk on Ubuntu 24.04.
- Paid plans start around $50/month for more boxes and credits.
