Codex on the Fly

FlyDex is a remote web control plane for local desktop Codex sessions. It lets you read threads, send prompts, and handle approval requests from your phone or browser while the Codex runtime stays on your own Mac or Windows PC.

Open FlyDex on the desktop running Codex, run the one-line npx install command once if the local helper is missing, then scan the on-screen QR code with your phone and finish sign-in. FlyDex completes the handoff on the desktop and opens the workspace when Codex is ready.

FlyDex currently connects local Codex on macOS and Windows. The remote control surface runs in a phone or browser, so you can approve actions and work with threads away from the desktop that is running Codex.

No. FlyDex keeps the Codex runtime on your local desktop. FlyDex stores the minimal account, machine, billing, and audit metadata it needs for routing and continuity, but it does not persist prompt bodies, chat content, Codex output, thread previews, or token-usage summaries at rest.

FlyDex uses a local connector plus an authenticated relay with short-lived, single-use pairing claims. The connector binds to 127.0.0.1 on the desktop, machines stay scoped to the account that paired them, and higher-risk actions such as command execution or file writes still require approval in the UI.

FlyDex currently offers a one-time 72-hour trial. After that, the product offer in FlyDex is $10 per month in USD, with card, Apple Pay, or Google Pay shown where Stripe makes those options available.
