Close the tab. Your agent keeps working.
Give Claude Code or Codex the long job, shut the laptop, go to bed. Your box stays on all night with Docker, sudo and four agent CLIs ready at login. $5 a month.

Every Codex and Claude limit on one board
Connect each subscription once. The board shows how much of every five-hour and weekly window is gone and the minute it refills. When a window you used up refills, an email tells you: go run your agents.

Codex connects with a device code, Claude with the code from its sign-in page. Connect once; the board keeps itself current.
On your laptop, the agent dies with the lid
Close the lid and the refactor stops halfway. Wi-Fi drops on the train and the session is gone. The limit you pay for resets at 3 a.m. and sits unused until you wake up.
A bare VPS fixes the lid and eats an evening: Docker, tmux, four CLIs, logins, and a token file you copy around by hand.
| Option | Keeps running when you leave | Docker | Terminal tabs that persist | All limits on one board | Smallest always-on option, a month |
|---|---|---|---|---|---|
| Your laptop | Until the lid closes | Yes | While it is awake | No | Your battery |
| Bare VPS (Hetzner CX23) | Yes | You install it | You set up tmux | No | €5.49, 40 GB |
| GitHub Codespaces | Stops when idle | Yes | Until it stops | No | 2 cores, $0.18 an hour: about $131 a month left running |
| Terminalbox Base | Yes | No | 1 | No | €6, 50 GB |
| detachbox Start | Yes, around the clock | Yes, with compose | Up to 10 | Yes | $5, 50 GB |

What is on your box the minute it starts
Ubuntu 26.04 LTS with sudo, configured the way you would do it, without losing the evening.
Tabs that outlive your browser
Every terminal tab is a tmux session on the box, up to ten per box. Close it on the laptop and open it on your phone: the scrollback is waiting.
The agent that needs you, flagged
Terminals mode lists every tab on every box as Working, Needs you or Idle. Answer the quiet one and ignore the rest.
Your whole stack next to the agent
Docker Engine with the compose plugin. Postgres, Redis and your app run beside the agent, so it tests against the real thing.
Your agent, ready at login
Claude Code, Codex, OpenCode or Gemini CLI, preinstalled and self-updating. Every new tab opens straight into the box's agent, approvals off.
Every port, an HTTPS link
Your dev server answers at https://<port>-<box>.detachbox.dev with hot reload. Private to you until you share it.
SSH like any server you own
ssh [email protected] with your own keys. Forward a port to the dev server and script the rest.
Approve a step from the bus
Claude Code Remote Control and Happy are on the box. Your phone drives a run you started at the desk.
Grows without a rebuild
Move from Start to Max and CPU, memory and disk grow on the running box. You pay the difference for the rest of the month.
What people hand their agents

Built for full Docker, with one bet behind it
Full Docker and sudo on a $5 box. Here is how your box is built, and the one bet behind it.
- Tokens
Refresh tokens never enter the box
Your Codex and Claude refresh tokens stay encrypted on our server. The box gets an access token that we renew on schedule. An agent running with sudo holds nothing that can mint a new one.
- Bet
Our bet: one kernel, many boxes
Boxes are unprivileged system containers with isolated user namespaces on a shared kernel, with nesting on so Docker runs inside. We bet that a shared kernel, patched every week, is the right price for full Docker at $5. The price is one planned reboot a month, emailed 48 hours ahead.
- Network
Walled off from its neighbours
Each box reaches the public internet at 50, 100 or 200 Mbit by plan. Private networks, our servers, neighbouring boxes and outbound mail on port 25 are blocked for every box.
- Reboots
Reboots keep your files
Planned reboots come with 48 hours' notice by email, enough to let a long run finish. Files, Docker images and volumes survive and boxes start on their own; running processes and tmux sessions start fresh.
- Read the security model
Your agent works around the clock, from $5 a month
Pick a size. The price covers the machine around the clock: no hourly billing and no sleep timer.

Questions before you start a box
What happens when I close the tab?
Nothing stops. The tab was a window onto a tmux session on your box. Open the dashboard from any browser or phone, or ssh in, and you land in the same session with the scrollback intact.
Do I need an API key?
No. Claude Code and Codex run on the subscriptions you already pay for. Connect them in the dashboard, or sign in inside the box the way you do on your laptop.
Is it safe to connect my Claude or ChatGPT account?
Your refresh token stays encrypted on our server and never reaches the box. The box gets an access token for the CLI. Disconnect the account and we delete its tokens from our server and from every box that used it.
Can I run Docker and databases?
Yes. Docker Engine and the compose plugin are installed, you are in the docker group and you have sudo. Images and volumes count toward your plan's disk.
What if the node reboots?
Files, Docker images and volumes stay. Your box starts on its own; running processes and tmux sessions start fresh. Planned reboots come with 48 hours' notice by email.
Why is there no free trial?
Every box is paid, so the CPU you pay for stays yours: free tiers fill up with crypto miners. Start at $5 and cancel from the dashboard whenever you like; the box stays yours to the end of the month.
Where do the boxes run?
In Kazakhstan, on our own hardware. Central Asia gets the lowest ping; everywhere else, the agent works on the box, so distance only touches your keystrokes. Anyone, anywhere can sign up.
Can my team share one box?
A box belongs to one person. Give each teammate a box of their own; at $5 it costs less than the argument over whose agent is eating the CPU.
How many boxes can I run?
Several, each on its own plan. Mix sizes as you like, and write to us when you plan a larger fleet.
How do I cancel?
In the dashboard, through the billing portal. The box keeps running to the end of the month you paid for.
Hand your agent the night shift
Start a box, give Claude Code or Codex the long job and close the tab. The work waits for you in the scrollback.
