Start in a real Linux terminal.
Choose an agent template, sign in with the provider account you already use, clone your repository, and work through the same CLI interface you know.
▍ Live product story · three steps
Close the laptop.
Not the session.
A local process pauses when its machine sleeps. Terminalbox moves the terminal to a hosted Linux workspace, so your coding agent can keep going and the same interactive shell is waiting on your next screen.

Start the task
The agent works in a hosted terminal.
The process and project live on Terminalbox—not on the laptop.
Hosted process The agent runs away from your laptop
Persistent tmux Reconnect to the same interactive shell
Provider choice Claude Code, Codex, Gemini, and more
Flat monthly price No metered Terminalbox compute bill
What the demo proves
Persistence needs a machine that stays awake.
A terminal multiplexer can survive a dropped connection, but it cannot make a sleeping laptop execute code. Terminalbox provides the always-on machine and puts every agent pane inside tmux, so both parts of the problem are covered.
Disconnect without stopping it.
Close the browser, switch networks, or shut the laptop. The workspace, agent process, files, development servers, and tmux session remain on the host.
Return to the same terminal state.
Attach from another browser or the Terminalbox CLI. You see the output produced while you were away and can type the next instruction immediately.
The narrow use case
Built for work that should outlive a tab.
Good fit
- Repository-wide refactors and test runs
- Agents you want to check from a phone or iPad
- Multiple terminal tools sharing one home directory
- Developers who want a shell, not a provider-specific task UI
Probably overkill
- Tasks that always finish while you stay at your desk
- Teams that already operate their own always-on dev server
- Workflows that never need an interactive terminal
Before you pay
Three practical answers.
Does my laptop need to stay awake?
No. Paid coding-agent panes run on Terminalbox’s hosted Linux machine. Your local device is only the screen and keyboard you use to attach.
Is it really the same terminal session?
Yes. Each pane uses a persistent tmux session. Reopening the pane attaches to the running process and its terminal state rather than starting a replacement chat.
Do I need another AI subscription?
You bring the Claude, OpenAI, Gemini, or other provider account you already use. Terminalbox charges for the hosted terminal and workspace, not model usage.
Try the real thing
One persistent agent terminal starts at €6/month.
