The execution host stays available
Codex runs in a hosted environment instead of depending on your laptop. Paid terminals and their processes continue when you close the browser or put your own computer to sleep.
▍ Codex hosting
Host Codex. Skip the VPS work.
Run the actual Codex CLI in a prepared Debian environment that stays online. Return through the browser or SSH without operating a server.

What changes
The terminal becomes a place you return to.
The Codex workspace is prepared
Start from a Codex template with a full Debian shell, Git, package managers, networking, persistent storage, and tmux already in place.
Hosting cost is predictable
Base is €6 per month for one persistent terminal with 2 vCPU, 4 GB RAM, and 50 GB of workspace. Terminalbox does not add per-minute compute charges.
How it works
From sign-in to a persistent session.
- 01
Choose Base for one Codex environment
Use Pro or Max only when you need several agent terminals running in parallel. Every paid plan includes persistent storage and browser access.
- 02
Open the Codex template and sign in
Authenticate Codex with the eligible ChatGPT plan or OpenAI API access you already manage. OpenAI access and usage remain separate from hosting.
- 03
Work in the browser or connect over SSH
Clone the repository, run Codex, and detach when you leave. Return to the same environment through Terminalbox, your SSH client, or a compatible Codex remote workflow.
Before you start
Questions worth answering.
What does Codex hosting add to Codex?
Terminalbox supplies the persistent Linux execution environment: compute, storage, browser terminal, SSH access, and tmux. OpenAI supplies Codex, its models, authentication, and usage allowance.
Is Codex or OpenAI usage included in the €6 price?
No. You bring an eligible ChatGPT plan or OpenAI API access. Terminalbox charges only for the hosted environment, and OpenAI controls Codex availability, limits, and model charges.
Why not use Codex in ChatGPT or on my laptop?
Use OpenAI’s own surfaces when they already provide the workflow you need. Managed hosting is useful when Codex must work inside one persistent, interactive Linux shell that stays available independently of your laptop.
Can I connect the official Codex app to this environment?
OpenAI documents Remote SSH for connecting Codex to remote environments. Terminalbox provides SSH access on paid agent plans, but OpenAI controls current client support and account availability, so check its current remote-connection guidance before buying for that workflow.
When is a DIY VPS the better choice?
Choose a VPS when you need root access, custom kernel or firewall control, a dedicated public IP, or want to own server hardening and maintenance. Terminalbox is a managed container and intentionally does not provide host-level control.
What survives when I close the browser?
On paid plans, the hosted environment, persistent home directory, running processes, and tmux session continue while your subscription is active. Reopening the terminal attaches to the same workspace.
Persistent by default
