Full Linux VM with Docker, git, and 200+ tools. Persistent sessions. No timeouts. From $6/mo.
Codex writes code, installs packages, runs builds, starts services. It needs a real machine.
KVM virtual machine with its own kernel. Not a container. Codex can install packages, run Docker, modify system configs without restrictions.
Sessions persist indefinitely. Let Codex work overnight. Come back to finished results. No idle disconnects, no hour limits.
Every major language runtime, Docker, databases, build tools. Pre-installed from a memory snapshot so nothing counts against your disk.
Create an account. Your VM boots from a memory snapshot in seconds. 200+ tools are ready to go.
Standard SSH from any client. Or use the browser-based terminal with Mosh over WebTransport. Codex is pre-installed — set your API key and go. Setup guide
Start Codex. Close your laptop. Sessions persist through disconnects, reboots, and network changes. Check back from any device.
A managed Linux machine running Ubuntu 24.04. Docker and Compose work natively. PostgreSQL, Redis, nginx are pre-installed. Go, Rust, Python, Node, Ruby, Java, PHP, Zig, Bun, Deno. git, gh, ripgrep, jq, neovim, and about 190 more tools.
All of it is loaded into a memory snapshot, so nothing counts against your disk quota and the VM boots in seconds. Your home directory persists across restarts.
Each shell has a public IPv6 address and a dev preview URL. Start a web server on any port, share the link. Codex can stand up a full stack and you can see it running immediately.
