# muxplex

**Web-based tmux session dashboard — access, monitor, and manage all your tmux sessions from any browser on any device.**

![muxplex dashboard](https://raw.githubusercontent.com/bkrabach/muxplex/main/assets/branding/og/og-dark.png)

---

## Features

### Dashboard

- **Live session grid** — preview tiles with ANSI-colored terminal snapshots, auto-refreshed
- **Two view modes** — Auto (scrollable grid) and Fit (all sessions fill the viewport)
- **Hover preview** — full-size overlay of session content on tile hover
- **Activity indicators** — bell notification badges on tiles; amber favicon dot + `(N)` count in browser tab title when sessions have unseen activity
- **Session creation** — `+` button with device selector dropdown when multi-device is enabled; custom command template support
- **Session deletion** — `×` button with custom command template support
- **Mobile-friendly** — responsive layout, PWA-capable for home-screen install

### Terminal

- **Full interactive terminal** — powered by xterm.js + ttyd
- **Native clipboard** — Ctrl+Shift+C to copy, Cmd+V (macOS) / Ctrl+Shift+V (Linux) to paste
- **Mouse select auto-copy** — selecting text copies to system clipboard on release
- **OSC 52 tmux clipboard bridge** — tmux copy mode selections go to system clipboard
- **Search** — Ctrl+F opens a search bar to find text in terminal scrollback (xterm-addon-search)
- **Clickable URLs** — Ctrl+Click (Cmd+Click on macOS) opens URLs in terminal output in a new tab (xterm-addon-web-links)
- **Inline image rendering** — Sixel and iTerm2 graphic protocols for tools like yazi file manager (xterm-addon-image)
- **Sidebar session switcher** — quick-switch between sessions with live previews

### Settings

- **In-browser settings panel** — gear icon or `,` shortcut
- **Display** — font size, grid columns, hover delay, view mode, device badges, activity indicator
- **Sessions** — default session, sort order, hidden sessions, auto-open, bell sound, notifications
- **Commands** — custom create/delete session templates
- **Multi-Device** — remote instance federation
- **CLI** — `muxplex config list/get/set/reset`

### Multi-Device

- **Remote session aggregation** — federate multiple muxplex instances into a unified dashboard view
- **Device selector in new session** — `+` button shows a device dropdown when multi-device is enabled; create sessions on any connected instance directly from the dashboard
- **Remote bell-clear** — opening a session on a remote device automatically clears its activity notification via federation API (`POST /api/bell/clear`)
- **Unique session keys** — sessions identified by `remoteId:name` across devices, preventing bell-state collisions for identically-named sessions on different machines

### Service Management

- `muxplex service install/start/stop/restart/status/logs/uninstall`
- **Platform-aware** — systemd user service on Linux/WSL, launchd agent on macOS
- **Config-driven** — service reads all options from `~/.config/muxplex/settings.json` (no flags in the service file)

### Authentication

- **PAM authentication** — Linux/macOS system credentials
- **Password mode** — auto-generated or set via `MUXPLEX_PASSWORD` env var
- **Localhost bypass** — no auth needed on 127.0.0.1
- **Secure session cookies** — signed with configurable TTL

### Developer Tools

- `muxplex doctor` — dependency + config diagnostics with update check
- `muxplex upgrade` — smart version check + auto-update + service restart
- `muxplex config` — CLI settings management

### HTTPS / TLS

- `muxplex setup-tls` — auto-detect and set up TLS certificates
- **Tailscale** — real Let's Encrypt certs via `tailscale cert` (recommended)
- **mkcert** — locally-trusted certs, zero browser warnings
- **Self-signed** — fallback for immediate HTTPS (browser shows warning)
- Required for browser clipboard API on non-localhost

---

## Prerequisites

- **Python 3.11+** — installed via `uv` or system Python
- **tmux** — terminal multiplexer
  - macOS: `brew install tmux`
  - Ubuntu/WSL: `sudo apt install tmux`
- **ttyd** — terminal sharing over HTTP (required for interactive terminal access)
  - macOS: `brew install ttyd`
  - Ubuntu/WSL: `sudo apt install ttyd` or `sudo snap install ttyd`
  - Other: https://github.com/tsl0922/ttyd#installation

> **Tip:** Run `muxplex doctor` to check all dependencies and system status.

---

## Quick Start (uvx — no install)

Run muxplex directly without installing anything permanently:

```bash
uvx --from git+https://github.com/bkrabach/muxplex muxplex
```

Then open **http://localhost:8088** in your browser.

> **Note:** `uvx` is part of [uv](https://docs.astral.sh/uv/). Install uv with `curl -LsSf https://astral.sh/uv/install.sh | sh`.

---

## Install Permanently

```bash
uv tool install git+https://github.com/bkrabach/muxplex
muxplex doctor  # verify dependencies
```

Then run it any time with:

```bash
muxplex
```

---

## Install as a Service

```bash
muxplex service install
# → prompts to set host to 0.0.0.0 for network access
```

The service starts automatically on login (macOS) or at boot (Linux) and restarts on failure.

```bash
# Open in browser
open http://localhost:8088
```

To stop and remove:

```bash
muxplex service uninstall
```

---

## CLI Reference

```
muxplex                              Start server (default)
muxplex serve [flags]                Start with CLI flag overrides
muxplex service install              Install + enable + start as OS service
muxplex service uninstall            Stop + disable + remove
muxplex service start|stop|restart   Manage running service
muxplex service status               Show service status
muxplex service logs                 Tail service logs
muxplex config                       Show all settings
muxplex config get <key>             Show one setting
muxplex config set <key> <value>     Set a setting
muxplex config reset [key]           Reset one or all to defaults
muxplex upgrade [--force]            Smart update with version check
muxplex doctor                       Check dependencies + config
muxplex show-password                Show current auth password
muxplex reset-secret                 Regenerate signing secret
muxplex setup-tls [--method auto]   Set up TLS certs (Tailscale/mkcert/self-signed)
muxplex setup-tls --status          Show current TLS configuration
```

### Service management

```bash
muxplex service install     # Write service file + enable + start
muxplex service uninstall   # Stop + disable + remove service file
muxplex service start       # Start the service
muxplex service stop        # Stop the service
muxplex service restart     # Stop + start
muxplex service status      # Show running/stopped + PID
muxplex service logs        # Tail service logs
```

The service runs `muxplex serve` with no flags — it reads all options from `~/.config/muxplex/settings.json`. To change host/port, edit the config (or use the Settings UI in the browser) and restart:

```bash
muxplex config set host 0.0.0.0
muxplex service restart
```

### Examples

```bash
# Start with defaults from settings.json
muxplex

# Override port for this run only
muxplex --port 9000

# Override host for this run only
muxplex serve --host 0.0.0.0
```

### HTTPS / TLS setup

```bash
# Auto-detect the best TLS method and set up certificates
muxplex setup-tls

# Use a specific TLS method
muxplex setup-tls --method tailscale
muxplex setup-tls --method mkcert
muxplex setup-tls --method selfsigned

# Show current TLS status and configuration
muxplex setup-tls --status

# Override TLS cert/key for a single run (without saving to config)
muxplex serve --tls-cert /path/cert.pem --tls-key /path/key.pem

# Check TLS configuration and dependencies
muxplex doctor
```

Auto-detection priority: **Tailscale** (if `tailscale` is installed and a cert is available) → **mkcert** (if `mkcert` is installed) → **self-signed** (always available as a fallback). Use `--method` to override.

> **Note:** Tailscale certs have a 90-day expiry. Run `muxplex setup-tls --method tailscale` to renew when needed.
