 # kitty-web
 
-Mobile-first web terminal powered by [ttyd](https://github.com/tsl0922/ttyd) + [tmux](https://github.com/tmux/tmux). One persistent tmux session, multiple tabs, accessible from any browser. Designed for phones and tablets.
+Run the real [kitty terminal](https://sw.kovidgoyal.net/kitty/) in your browser. Mobile-friendly, GPU-accelerated, with full tab and split support.
+
+Powered by [Xpra](https://xpra.org/) — serves kitty as an HTML5 application via its built-in web client. This is not a terminal emulator in JavaScript; it's the actual kitty running on your server, streamed to your browser.
 
 ## Features
 
-- **Single persistent session** — one tmux session shared across all connected clients
-- **Mobile touch toolbar** — on-screen buttons for common shortcuts (new tab, ^C, ^D, Esc, arrows, split panes, etc.)
-- **Text selection mode** — tap `Sel` to enter selection mode, long-press to select and copy text, tap `Done` to resume typing
-- **Push notifications** — send browser notifications from any terminal command
-- **PWA installable** — add to home screen for an app-like experience
-- **Dark theme** — styled for dark-mode terminals with orange accents
+- **Real kitty** — GPU rendering, ligatures, image protocol, all of it
+- **Kitty tabs and splits** — native `ctrl+shift+t`, splits, layouts
+- **Persistent session** — close the browser, reconnect later, everything is still there
+- **Multi-client** — multiple browsers can view/interact with the same session
+- **Mobile-friendly** — Xpra's HTML5 client handles touch input, keyboard, and scaling
+- **Push notifications** — optional notification API for long-running commands
 
 ## Architecture
 
 ```
-Browser -> Caddy (HTTPS + Auth) -> ttyd (port 7681) -> tmux session
-                                -> notify-server (port 7682) -> /api/notifications
+Browser -> Caddy (HTTPS + Auth) -> Xpra HTML5 (port 7681) -> kitty
 ```
 
-- **ttyd** serves the terminal UI with a custom index page that loads `toolbar.js`
-- **toolbar.js** injects the mobile toolbar (shortcut buttons, selection mode) into the page at runtime
-- **notify-server.py** provides a simple HTTP endpoint for push notifications
-- **kitty-notify** is a CLI command to trigger notifications from scripts
+Xpra runs kitty inside a virtual X display (Xvfb) and streams the rendered output to browsers via WebSocket. The HTML5 client handles input, clipboard, and display scaling.
 
 ## Quick Start
 
+### Prerequisites
+
+- Debian/Ubuntu (tested on Debian 13 Trixie)
+- kitty (`apt install kitty`)
+- Xpra (`https://xpra.org/` — add their repo for latest version)
+
+### Install
+
 ```bash
-sudo ./install.sh
+# Add Xpra repo (Debian example)
+curl -sL https://xpra.org/xpra.asc | sudo tee /usr/share/keyrings/xpra.asc
+echo "deb [signed-by=/usr/share/keyrings/xpra.asc] https://xpra.org/ $(lsb_release -cs) main" | \
+  sudo tee /etc/apt/sources.list.d/xpra.list
+sudo apt update && sudo apt install -y xpra kitty
+
+# Create a service user (optional)
+sudo useradd -m -s /bin/bash rdp
+
+# Install systemd service
+sudo cp systemd/kitty-web.service /etc/systemd/system/
+sudo systemctl daemon-reload
+sudo systemctl enable --now kitty-web
 ```
 
-This installs ttyd, tmux, systemd services, and the notification system. The terminal will be available at `http://YOUR_IP:7681`.
+### Manual Start
+
+```bash
+xpra start --bind-ws=0.0.0.0:7681 \
+    --start="kitty" \
+    --html=on \
+    --sharing=yes \
+    --no-daemon
+```
+
+Then open `http://YOUR_IP:7681` in a browser.
 
 ### Configuration
 
-Set environment variables before running the installer:
+Edit `systemd/kitty-web.service` to customize:
 
-| Variable | Default | Description |
-|----------|---------|-------------|
-| `KITTY_USER` | `rdp` | System user that owns the tmux session |
-| `TTYD_PORT` | `7681` | Port for ttyd web terminal |
-| `NOTIFY_PORT` | `7682` | Port for notification API |
-| `FONT_SIZE` | `18` | Terminal font size (optimized for mobile) |
+| Option | Description |
+|--------|-------------|
+| `--bind-ws=HOST:PORT` | WebSocket listen address |
+| `--start="CMD"` | Application to launch (default: `kitty`) |
+| `--sharing=yes` | Allow multiple clients to connect |
+| `--readonly=no` | Allow keyboard/mouse input |
 
-### Reverse Proxy
+### Reverse Proxy (Caddy)
 
-See `caddy-example.conf` for a complete Caddy v2 configuration with authentication. The setup supports OAuth2 Proxy, Authentik, or Authelia for access control.
-
-Key requirements for the reverse proxy:
-- WebSocket support (ttyd uses WebSockets for terminal I/O)
-- Serve `/toolbar.js`, `/manifest.json`, `/icon-*.png` as static files
-- Proxy `/api/*` to the notification server (port 7682)
-- Proxy everything else to ttyd (port 7681)
-
-## Mobile Toolbar
-
-The toolbar appears automatically on screens narrower than 900px. Buttons:
-
-| Button | Action | tmux Key |
-|--------|--------|----------|
-| **+Tab** | New tab | `Ctrl-A c` |
-| **Next** | Next tab | `Ctrl-A n` |
-| **Prev** | Previous tab | `Ctrl-A p` |
-| **^C** | Interrupt | `Ctrl-C` |
-| **^D** | EOF / logout | `Ctrl-D` |
-| **Clr** | Clear screen | `Ctrl-L` |
-| **Esc** | Escape key | `Escape` |
-| **Tab** | Tab completion | `Tab` |
-| **Up/Down** | History navigation | Arrow keys |
-| **Sel** | Toggle text selection mode | — |
-| **Spl** | Split pane vertically | `Ctrl-A %` |
-| **Pane** | Cycle between panes | `Ctrl-A o` |
-| **Kill** | Kill current pane/tab | `Ctrl-A x` |
-
-## Push Notifications
-
-Send notifications from any terminal session:
-
-```bash
-# Direct message
-kitty-notify "Build complete!"
-
-# Pipe output
-echo "Deploy finished" | kitty-notify
-
-# Use in scripts
-make build && kitty-notify "Build succeeded" || kitty-notify "Build FAILED"
+```
+terminal.example.com {
+    # Add your auth here (OAuth2 Proxy, Authentik, etc.)
+    reverse_proxy YOUR_SERVER:7681
+}
 ```
 
-Notifications appear as browser push notifications on mobile. Tap the bell icon in the terminal UI to enable them. Notifications expire after 30 seconds.
+WebSocket support is required. Caddy handles this automatically. See `caddy-example.conf` for a full example with authentication options.
 
-## tmux Keybindings
+### Kitty Config
 
-The included tmux config uses `Ctrl-A` as the prefix (easier on mobile than the default `Ctrl-B`):
+Place your kitty config at `~/.config/kitty/kitty.conf` for the service user. See `config/kitty.conf` for a dark-themed example.
 
-| Key | Action |
-|-----|--------|
-| `Ctrl-A c` | New window/tab |
-| `Ctrl-A n` / `Ctrl-A p` | Next / previous window |
-| `Ctrl-A %` / `Ctrl-A "` | Split vertical / horizontal |
-| `Ctrl-A o` | Cycle panes |
-| `Ctrl-A x` | Kill pane |
-| `Alt-1` through `Alt-5` | Jump to window 1-5 |
-| `Alt-Left` / `Alt-Right` | Previous / next window |
-| `Alt-t` | New window |
-| Mouse scroll | Scroll through history |
+## Optional: Push Notifications
+
+The `notify-server.py` and `kitty-notify` command provide a simple browser notification system:
+
+```bash
+# Install
+sudo cp notify-server.py /opt/kitty-web/
+sudo cp kitty-notify /usr/local/bin/
+sudo cp systemd/kitty-notify.service /etc/systemd/system/
+sudo systemctl enable --now kitty-notify
+
+# Usage
+kitty-notify "Build complete!"
+echo "done" | kitty-notify
+```
+
+Requires proxying `/api/*` to port 7682 — see `caddy-example.conf`.
