Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@nervmor/codexui) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

🤯 What Is This?

@nervmor/codexui is a lightweight bridge that gives you a browser-accessible UI for Codex app-server workflows.

You run one command. It starts a local web server. You open it from your machine, your LAN, or wherever your setup allows.

TL;DR 🧠: Codex app UI, unlocked for Linux, Windows, and Termux-powered Android setups.

⚡ Quick Start

The main event.

# 🔓 Run instantly (recommended)
npx @nervmor/codexui

# 🌐 Then open in browser
# http://localhost:18923

By default, @nervmor/codexui now also starts:

cloudflared tunnel --url http://localhost:<port>

It prints the tunnel URL, terminal QR code, and password together in startup output.
Use --no-tunnel to disable this behavior.

Linux 🐧

node -v   # should be 18+
npx @nervmor/codexui

Windows 🪟 (PowerShell)

node -v   # 18+
npx @nervmor/codexui

Termux (Android) 🤖

pkg update && pkg upgrade -y
pkg install nodejs -y
npx @nervmor/codexui

Android background requirements:

Keep the codexui session running in the current Termux session (do not close it).
In Android settings, disable battery optimization for Termux.
Keep the persistent Termux notification enabled so Android is less likely to kill it.
Optional but recommended in Termux:

termux-wake-lock

Open the shown URL in your Android browser. If the app is killed, return to Termux and run npx @nervmor/codexui again.
