Codex is OpenAI's coding agent. On your machine it works while the terminal is open and stops when it isn't. Long tasks need a computer that stays on, and most people don't want to run one.
Hivra hosts the official Codex CLI on a private VM that stays on. Sign in with your own ChatGPT account, or use your own OpenAI API key, on the computer after launch. Then hand it real work: a repo to inspect, a change to implement, a failing build to debug.
Start long work inside tmux in the computer's Terminal tab and it keeps going after you log off. Plans start at $9.99 a month for 2 vCPU and 4 GB RAM, with room for the optional live browser, and paid plans are never paused for inactivity. When you sign in with ChatGPT or your own OpenAI key, Codex usage bills through that account, not through Hivra.
What you get
- Official OpenAI Codex CLI, unmodified. Sign in with ChatGPT or your own API key.
- Optional live self-hosted browser for research and logged-in sites.
- Web terminal, files, and skills, reachable from any device.
How it works
- Sign up and launch CodexLaunch opens with Codex selected. Choose where it runs and a plan, name the agent, and choose resources. The live browser is optional.
- Hivra provisions a private VMThe official CLI is already installed when your computer comes up.
- Sign in with your ChatGPT accountThe sign-in happens on the computer, or you can use your own OpenAI API key instead. Your session is stored there.
- Hand off long runsChat with it while you watch. Start long runs inside tmux in the computer's Terminal tab, and they keep going while you're offline.
Self-hosted vs managed, honestly
- DIY: a VPS, the CLI install, a tmux session you keep alive, and updates you apply by hand.
- Hivra provisions the computer and keeps it on around the clock on any paid plan, with tmux already installed for long runs.
- You get chat, a web terminal, files, and an optional live browser instead of a bare shell.
- Same official CLI and the same ChatGPT billing either way. You're paying Hivra to skip the ops.
Common questions
What does it cost to run Codex in the cloud?
Plans start at $9.99 a month for 2 vCPU and 4 GB RAM. A $19.99 plan gives you 4 vCPU and 8 GB. Codex usage bills through your own ChatGPT or OpenAI account. Card payments come with a 7-day money-back guarantee.
Do I need an OpenAI API key?
No. You can sign in with your own ChatGPT account on the computer after launch, or use your own OpenAI API key if you prefer. Either way the credentials live on your agent computer, and Hivra administrators keep infrastructure access to Hivra-managed hosts.
What happens when I close my laptop?
The computer stays on and keeps your files, sessions and ChatGPT login, and paid plans are never paused for inactivity. A run you start inside tmux in the computer's Terminal tab keeps going, and you pick up the result later from any device.
Can Codex browse the web on Hivra?
Yes. Codex computers ship the same live browser stack as Claude Code computers. Turn it on for web research or logged-in sites. It adds 1 vCPU and 2 GB RAM to the computer, which fits within the $9.99 plan.
Is this a modified version of Codex?
No. It's the official CLI from OpenAI, running unmodified on a private VM. Hivra is an independent hosting service and isn't affiliated with or endorsed by OpenAI.
Can I run Hivra on my own server instead?
Hivra's own source is open source at github.com/ashneil12/hivra, and you can self-host it. The managed plans are for people who would rather not run the server themselves.
Hivra is independent and is not affiliated with OpenAI.
