Codex CLI°

managed by jurniti · upstream OpenAI

Run OpenAI Codex on a real microVM — the terminal-first coding agent, your ChatGPT subscription, fully isolated.

  • Fresh Ubuntu microVM with the Codex CLI pre-installed and on your PATH.
  • Live in-browser terminal — sign in with your ChatGPT account (codex login) or bring an OPENAI_API_KEY.
  • Persistent home — your config, prompts, and AGENTS.md survive every restart.
  • Snapshot into a forkable template — share the setup, never the credentials (scrubbed on publish).
  • Real Firecracker microVM isolation. Not a shared Docker container.
Flat monthly · no metered surprises
$250 / yr Starter($20.83/mo · 2 months free)

30-day money-back guarantee. Provision in ~3 minutes after payment. Codex CLI comes pre-staged in your VM — you just paste the install command.

jurniti is the platform — Codex CLI is the harness running inside your microVM. Compare all the harnesses →
