README

pi-web-ui

Web chat interface for the pi coding agent SDK — chat in the browser, browse the file tree, attach files, built-in terminal (xterm.js + node-pty), model management, sound notifications, Chinese/English UI.

Fork of xing-shuyin/pi-web-ui with personal fixes (e.g. Kimi-style </antThinking> leaked-reasoning tags).

Requirements

  • Node.js >= 22.19.0
  • A configured pi agent (~/.pi/agent, e.g. via pi CLI) with at least one model provider

Install & run

npm i -g @youweichen/pi-web-ui
pi-web-ui                 # http://127.0.0.1:8787
pi-web-ui --port 9000 --cwd /path/to/project

or without installing:

npx @youweichen/pi-web-ui

Upgrade

npm i -g @youweichen/pi-web-ui@latest
pi-web-ui server restart   # if you installed the autostart service

Autostart on boot

pi-web-ui server install    # macOS → launchd, Linux → systemd, Windows → Task Scheduler
pi-web-ui server status     # start | stop | restart | uninstall also available

Desktop app (Electron)

There's also an Electron shell around the same server/UI — a native window with a tray icon instead of a browser tab.

Download: prebuilt installers (mac dmg/zip, Windows nsis/portable/zip, Linux AppImage/deb) are published to GitHub Releases whenever a v* tag is pushed. Unsigned, so macOS Gatekeeper will refuse the first launch — right-click the app and choose "Open" to bypass it once.

Or build it yourself from source:

npm install
npm run build              # build:web + build:server first
npm run dev:electron       # run the shell against the local build
npm run build:electron:mac # or :win / :linux — produces an installer under release/

The Electron window loads the same server as the CLI (server/index.ts), just spawned as a hidden child process instead of opening a browser tab. Desktop-app data lives in ~/.pi-web-desktop (separate from the CLI's ~/.pi-web, so the two don't fight over client-state.json if you run both — chat history itself is shared, it lives in ~/.pi/agent).

See docs/deployment.md for details.

Notes

  • Binds to loopback (127.0.0.1) by default; set PI_WEB_HOST to expose on LAN.
  • Optional shared-password auth: PI_WEB_TOKEN=secret pi-web-ui.
  • node-pty is a native module — on Windows you may need Visual Studio Build Tools if no prebuilt binary matches.

中文简介

pi 编码智能体的 Web 聊天界面：浏览器对话、文件树、附件、内置终端、模型管理、声音提醒、中英文切换。全局安装后一条命令启动，支持开机自启（launchd / systemd / Windows 计划任务）。

也有一个 Electron 桌面版壳子（原生窗口 + 托盘，不用开浏览器标签页）——打 v* tag 后 CI 会自动把 mac/win/linux 安装包发到 GitHub Releases，未签名，mac 首次打开需要右键「打开」跳过 Gatekeeper；也可以自己本地源码构建（npm run build:electron:mac/:win/:linux），见 docs/deployment.md。
