**A sleek, dark-themed webchat UI for [OpenClaw](https://github.com/openclaw/openclaw) — monitor sessions, stream responses, and inspect tool calls in real-time.**
|
|
|
|
> 🎬 **[See the live demo →](https://marlburrow.github.io/pinchchat/)** — interactive preview of the UI with tool call visualization, streaming, and more.

## ✨ Features
|
|
|
|
- 🔧 **Tool call visualization** — see what your agent is doing in real-time: colored badges, visible parameters, expandable results. The killer feature missing from every other chat UI.
|
|
- 💬 **GPT-like interface** — sessions in a sidebar, switch between conversations. Familiar if you've used ChatGPT or Claude.
|
|
- 📋 **Multi-session navigation** — browse all active sessions including cron jobs, sub-agents, and background tasks
|
|
- ⚡ **Live streaming** — watch the agent think and write token by token
|
|
- 📊 **Token usage tracking** — progress bars per session so you know how much context is left
|
|
- 🖼️ **Inline images** — generated or read images render directly in chat with lightbox preview
|
|
- 🎯 **Chat-focused** — no settings menus or config panels cluttering the screen. Just the conversation.
|
|
- 🌐 **i18n** — English and French built-in, easy to extend
|
|

|
## 🚀 Quick Start
|
|
|
|
### Docker (recommended)
|
|
|
|
```bash
|
|
docker run -p 3000:80 ghcr.io/marlburrow/pinchchat:latest
|
|
```
|
|
|
|
Open `http://localhost:3000` and enter your OpenClaw gateway URL + token on the login screen.
|
|
|
|
Or use Docker Compose:
|
|
|
|
```bash
|
|
curl -O https://raw.githubusercontent.com/MarlBurroW/pinchchat/main/docker-compose.yml
|
|
docker compose up -d
|
|
```
|
|
|
|
### From source
|
|
|
|
**Prerequisites:** Node.js 18+, an OpenClaw gateway running and accessible.
|
|
|
|
```bash
|
|
git clone https://github.com/MarlBurroW/pinchchat.git
|
|
cd pinchchat
|
|
npm install
|
|
cp .env.example .env
|
|
npm run dev
|
|
```
|
|
|
|
Optionally edit `.env` to pre-fill the gateway URL:
|
|
|
|
```env
|
|
VITE_GATEWAY_WS_URL=ws://localhost:18789
|
|
VITE_LOCALE=en # or "fr" for French UI
|
|
```
|
|
|
|
### Production build
|
|
|
|
```bash
|
|
npm run build
|
|
npx vite preview
|
|
```
|
|
|
|
Or serve the `dist/` folder with nginx, Caddy, or any static file server.
|
|
|
|
## ⚙️ Configuration
|
|
|
|
All configuration is optional — credentials are entered at runtime via the login screen.
|
|
|
|
| Variable | Description | Default |
|
|
|---|---|---|
|
|
| `VITE_GATEWAY_WS_URL` | Pre-fill the gateway URL on the login screen | `ws://<hostname>:18789` |
|
|
| `VITE_LOCALE` | UI language (`en` or `fr`) | `en` |
|
|
|
|
> **Note:** The gateway token is entered at runtime and stored in `localStorage` — it is never baked into the build.

### Key Components
|
|
|
|
| File | Role |
|
|
|---|---|
|
|
| `src/hooks/useGateway.ts` | WebSocket connection, auth, message streaming, session management |
|
|
| `src/components/LoginScreen.tsx` | Runtime credential entry (stored in `localStorage`) |
|
|
| `src/components/Chat.tsx` | Message list with auto-scroll and streaming display |
|
|
| `src/components/ChatInput.tsx` | Input with file upload, paste, drag & drop, image compression |
|
|
| `src/components/ChatMessage.tsx` | Markdown rendering, tool calls, thinking blocks |
|
|
| `src/components/Sidebar.tsx` | Session list with token usage bars and activity indicators |
|
|
| `src/components/Header.tsx` | Connection status, token progress bar, logout |
|
|
| `src/lib/i18n.ts` | Lightweight i18n (English + French) |
|
|
| `src/lib/gateway.ts` | WebSocket protocol helpers and message types |
|
|
|
|
### Data Flow
|
|
|
|
1. **Login** — User enters gateway URL + token → stored in `localStorage`
|
|
2. **Connect** — `useGateway` opens a WebSocket and authenticates with the token
|
|
3. **Sessions** — Gateway pushes session list; user selects one in the sidebar
|
|
4. **Messages** — Messages stream in via WebSocket frames; the hook assembles partial chunks into complete messages
|
|
5. **Send** — User input (+ optional file attachments) is sent as a JSON frame over the WebSocket
