## 🤯 What Is This?

**`codexapp`** 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.**



```bash

# 🔓 Run instantly (recommended)

npx codexapp



# 🌐 Then open in browser

# http://localhost:18923

```



By default, `codexapp` now also starts:



```bash

cloudflared tunnel --url http://localhost:

```



It prints the tunnel URL, terminal QR code, and password together in startup output.  

Use `--no-tunnel` to disable this behavior.



If you are using a provider or AI gateway that is already authenticated and do not want `codexapp` to force `codex login` during startup, use:



```bash

npx codexapp --no-login

```



### Linux 🐧

```bash

node -v   # should be 18+

npx codexapp

```



### Windows 🪟 (PowerShell)

```powershell

node -v   # 18+

npx codexapp

```



### Termux (Android) 🤖

```bash

pkg update && pkg upgrade -y

pkg install nodejs -y

npx codexapp

```



Android background requirements:



1. Keep `codexapp` running in the current Termux session (do not close it).

2. In Android settings, disable battery optimization for `Termux`.

3. Keep the persistent Termux notification enabled so Android is less likely to kill it.

4. Optional but recommended in Termux:

```bash

termux-wake-lock

```

5. Open the shown URL in your Android browser. If the app is killed, return to Termux and run `npx codexapp` again.

## iPhone / iPad via Tailscale Serve



If you want to use codexUI from iPhone or iPad Safari, serving it over HTTPS is recommended.



A practical private setup is to run codexUI locally and publish it inside your tailnet with Tailscale Serve:



```powershell

npx codexapp --no-tunnel --port 5900

tailscale serve --bg 5900

```



Then open:



```text

https://..ts.net

```



This setup worked well in practice for:



- iPhone Safari access

- Add to Home Screen

- the built-in dictation / transcription feature in the app

- viewing the same projects and conversations from the Windows host



Notes:



- Tailscale Serve keeps access private to your tailnet

- on iOS, HTTPS / secure context appears to be important for mobile browser access and dictation

- some minor mobile Safari CSS issues may still exist, but they do not prevent normal use

- depending on proxying details, authentication behavior may differ from direct remote access

- if conversations created in the web UI do not immediately appear in the Windows app, restarting the Windows app may refresh them

## ✨ Features

> **The payload.**



- 🚀 One-command launch with `npx codexapp`

- 🌍 Cross-platform support for Linux, Windows, and Termux on Android

- 🖥️ Browser-first Codex UI flow on `http://localhost:18923`

- 🌐 LAN-friendly access from other devices on the same network

- 🧪 Remote/headless-friendly setup for server-based Codex usage

- 🔌 Works with reverse proxies and tunneling setups

- ⚡ No global install required for quick experimentation

- 🎙️ Built-in hold-to-dictate voice input with transcription to composer draft

- 🤖 Optional Telegram bot bridge: send messages to bot, forward into mapped thread, send assistant reply back to Telegram



### Telegram Bot Bridge (Optional)



Set these environment variables before starting `codexapp`:



```bash

export TELEGRAM_BOT_TOKEN=""

export TELEGRAM_ALLOWED_USER_IDS=","

export TELEGRAM_DEFAULT_CWD="$PWD" # optional, defaults to current working directory

npx codexapp

```



`TELEGRAM_ALLOWED_USER_IDS` is required for safe access. Only allowlisted Telegram user IDs can use the bridge. If no allowed user IDs are configured, incoming Telegram messages are rejected.



To find your Telegram user ID:



1. Send a message to your bot.

2. Run `curl "https://api.telegram.org/bot/getUpdates"`.

3. Read `message.from.id` from the returned update payload.



Bot commands:



- `/start` show quick help and thread picker

- `/threads` list recent threads and pick one

- `/newthread` create and map a new Codex thread for this Telegram chat

- `/thread ` map current Telegram chat to an existing thread

- `/current` show currently connected thread for this chat

- `/history` show recent history for current thread

- `/status` show bridge/mapping status

- `/whoami` show your Telegram user/chat IDs and authorization state

- `/help` show command reference



Outgoing assistant messages are sent with Telegram `parse_mode=HTML` for formatting, with automatic plain-text fallback if HTML delivery fails.
