Requires Codex Desktop already installed and running on the host machine, remote access over a public network is discouraged.

The README does not state a license.

So what is it?

OpenCodex is a lightweight runtime that lets you access OpenAI's Codex coding assistant from any device through a web browser, even when the official mobile or desktop app is unavailable in your region or requires a specific app store account. The README is written primarily in Chinese. The core problem it solves is that Codex Desktop is an Electron application, meaning it only runs on the computer where it is installed. OpenCodex bridges that desktop application to a web interface so you can connect to it remotely from a phone, tablet, or another computer. It works by running a local Node.js gateway on the machine where Codex Desktop is installed. This gateway handles authentication, HTTP and WebSocket communication, and routes requests between a browser-based shell and the official Codex renderer. A compatibility layer called a polyfill (a piece of code that fills in missing browser features) translates the calls that Codex's interface makes to Electron's native APIs into messages that can travel over a standard web connection. The official Codex UI is loaded as-is inside the web shell, so the full feature set including file browsing, terminal access, and task review remains available. Someone would use this if they want to run Codex AI coding sessions from a device other than their main computer, particularly in regions where the official Codex app is restricted or unavailable. Remote access is recommended over a private network like Tailscale or ZeroTier rather than directly over the public internet. The tech stack is TypeScript and Node.js 20.
