Snappier Server ships with a built-in browser-based dashboard. It runs on the same port as the API and requires no extra install — just point a browser at:

http://YOUR-SERVER-IP:8000/dashboard

The dashboard is the primary way to manage the server when you're not using the desktop app or the Snappier IPTV mobile app. It works on phones, tablets, and desktops, and supports both light and dark themes (toggle in the top nav).

Authentication

On first load you'll be prompted for the API token (auto-generated on first server launch — find it in the desktop Preferences window, the CLI console output, or ~/SnappierServer/config.json). The token is stored in localStorage so you only enter it once per browser. To rotate it, use Settings → Authentication → Regenerate.

Overview Cards

The home screen shows a live grid of count cards, each opening a detail modal:

• Scheduled Programs: upcoming one-shot and PVR recordings with start/stop times. Cancel from here.
• Recordings: completed live-TV recordings with size, duration, channel, and Comskip status. Play in-browser, download, or delete.
• Streaming Devices: active HLS sessions (transcoding) and remux sessions, plus connected client info.
• Movies / TV Series: downloaded VOD content with metadata, posters, and play/delete actions.
• PVR Rules: active series/one-time rules and the next match found in the EPG.
• Reminders: programme reminders and their fire times.
• System stats: CPU, memory, and per-folder disk usage updated live over SSE.

TV Guide (EPG Grid)

An interactive XMLTV-driven grid view. Browse channels by category, jump to "Now", scroll forward/back in time, and long-press / right-click any programme cell for actions: Watch live, Record once, Create PVR rule, or Set reminder. Live channel previews open in a built-in HLS player. Setup:

1. Dashboard → Settings → EPG → add a source.
2. Tick Use for TV Guide (Xtream Codes) if your provider uses Xtream — channel/category data is auto-fetched from the credentials embedded in the EPG URL.
3. Save. Click TV Guide in the top nav.

Settings Modal

Tabbed configuration UI — everything writes to config.json and most options apply without a restart (port changes are picked up live by the watcher):

• Server: port; toggles for Remux, Commercial Skipping (Comskip), and the alternative download engine; download speed limit; log rotation.
• Folders: per-purpose paths for Recordings, Movies, TV Series, PVR data, Logs, and EPG cache, with a folder browser.
• EPG: enable/disable EPG, manage multiple XMLTV sources with priorities, set refresh interval, mark a source for TV Guide use, and an Xtream URL helper.
• Auth: view, copy, and regenerate the API token.

Live Updates (SSE)

The dashboard subscribes to the server's Server-Sent Events stream, so you don't need to refresh. Job progress, recording starts/stops, remux completion, Comskip status, EPG refresh, PVR scans, and reminder fires all update the UI in real time. If the connection drops the dashboard reconnects automatically.

Mobile / Tablet

The layout collapses to a stacked card view on narrow screens; modals become full-screen sheets. The TV Guide grid is touch-scrollable with momentum.

Headless Servers

If you're running the CLI binary on a NAS or server with no GUI, the dashboard is your only management UI — everything the desktop Preferences window can do is also available here, plus the runtime panels (active jobs, logs, stats) that the desktop app doesn't have.

EPG (Electronic Programme Guide) provides programme listings for scheduling recordings and browsing the TV guide. Your IPTV provider supplies the EPG URL — look for "XMLTV URL", "EPG URL", or "TV Guide URL" in your provider's welcome email, customer portal, or app setup instructions. If you can't find it, contact your provider.

EPG URL Format

If your provider uses Xtream Codes (a common IPTV management system), construct the EPG URL from your provider's server details (not your Snappier Server):

http://your-provider-server:port/xmltv.php?username=USERNAME&password=PASSWORD

GUI Setup

1. Tray icon → Preferences → EPG section
2. Enable EPG, paste your URL, name the source, set priority (1 = highest)
3. Set refresh interval (24h recommended), Save

CLI Setup

# Single source
./snappier-server-cli --enable-epg \
  --epg-url "http://iptv.example.com:8080/xmltv.php?username=user&password=pass"

# Multiple sources
./snappier-server-cli --enable-epg --epg-urls '[
  {"url":"http://primary.com/epg.xml","name":"Primary","priority":1,"enabled":true},
  {"url":"http://backup.com/epg.xml","name":"Backup","priority":2,"enabled":true}
]'

Verify

curl -H "X-API-Token: YOUR_TOKEN" http://localhost:8000/epg/status     # Source info & update times
curl -H "X-API-Token: YOUR_TOKEN" http://localhost:8000/epg/channels   # Detected channels
curl -H "X-API-Token: YOUR_TOKEN" -X POST http://localhost:8000/epg/refresh  # Force refresh

Troubleshooting

• No data: Verify URL returns XML in a browser. Check EPG is enabled. Wait for initial download.
• Stale data: POST /epg/refresh or reduce refresh interval.
• URL not working: Verify credentials. Try standard Xtream format. Contact your provider.

PVR (Personal Video Recorder) creates rules that automatically schedule recordings when matching programmes appear in your EPG data. Like a DVR — set it once and the server records every matching episode.

Requirements

• EPG must be enabled and working
• Server should be running 24/7 for automatic scheduling

Rule Types

• Series: Records all future matching episodes continuously. Best for TV series and daily shows.
• One-time: Records only the next match, then auto-disables. Best for special events or one-off recordings.

How to Create Rules

• Snappier IPTV app: Long-press any programme in the EPG grid for recording options. Manage rules in the Server section.
• Web Dashboard: Open Settings → PVR Rules to create and manage rules.

How It Works

The server scans EPG data for matching programmes after each EPG refresh, on startup (2-second delay), or when you trigger a manual scan. Matched programmes are automatically scheduled for recording. You can exclude specific episodes you don't want.

Data Storage

PVR data is stored in the PVR_FOLDER (default: ~/SnappierServer/PVR/):

• pvr_rules.json — Recording rules
• pvr_exclusions.json — Excluded episodes
• Recordings saved as .ts (or .mkv with remuxing enabled)

Snappier Server bundles Comskip to detect commercial breaks in finished recordings. It is non-destructive — the original recording is untouched. Comskip writes a sidecar .edl file (Edit Decision List) next to the recording, and players that understand EDL (Kodi, MythTV, NextPVR, Jellyfin with the appropriate plugin) will skip those segments automatically on playback.

Enabling

• Web Dashboard: Settings → Server → Enable Commercial Skipping (Comskip).
• Desktop Preferences: Tick Enable Commercial Skipping.
• Environment: ENABLE_COMSKIP=true
• CLI: --enable-comskip

How It Works

When a live TV recording finishes (and remuxing completes if enabled), Comskip runs against the finished file. On completion the sidecar files are written next to the recording:

• recording.edl — commercial-break time ranges (used by players)
• recording.txt, recording.log, recording.logo.txt — diagnostic output (safe to delete)

Detection runs in the background — the recording is immediately playable, and EDL data appears once Comskip finishes. The recording's metadata (and dashboard listing) shows a comskip status of running, done, none, or failed. Live progress is also broadcast over the SSE event stream as comskipStarted / comskipDone / comskipFailed.

Platform Support

• macOS: Bundled binary for Apple Silicon (arm64). Intel Macs are not bundled — build from source if needed.
• Windows: Bundled comskip.exe (x86; runs on both 32-bit and 64-bit Windows).
• Linux: Bundled binaries for both x86_64 and aarch64 (ARM64). To rebuild from source: apt install autoconf libtool build-essential libargtable2-dev libavformat-dev, then ./autogen.sh && ./configure --without-sdl && make.

Tuning

Comskip's detection behaviour is controlled by comskip.ini, shipped alongside the binary. The bundled config produces standard EDL output; for fine-tuning (logo detection, channel-specific aspect ratios, sensitivity) consult the upstream sample ini.

Overriding the bundled binary or ini

You can point Snappier at an external comskip binary (e.g. a system-installed build) or a custom comskip.ini. Resolution order, highest precedence first:

1. Config file: comskip_path / comskip_ini in config.json (also accepts camelCase comskipPath / comskipIni). Picked up live when the config is saved — no restart needed.
2. Environment: COMSKIP_PATH / COMSKIP_INI.
3. CLI: --comskip-path <path> / --comskip-ini <path>.
4. Config-dir ini fallback: If no ini override is set, a comskip.ini placed next to your config.json is used in preference to the bundled one.
5. Bundled: The platform/arch-appropriate binary and ini shipped with Snappier.

If an override path is unreadable or non-executable, Snappier logs a warning and falls back to the next candidate. Example config.json snippet:

{
  "enable_comskip": true,
  "comskip_path": "/usr/local/bin/comskip",
  "comskip_ini": "/etc/snappier/comskip.ini"
}

Caveats

• Commercial detection is heuristic — expect occasional false positives or misses, especially on channels without clear ad breaks.
• Sidecar files are deleted automatically when you delete the recording from the dashboard.
• Detection runtime is roughly 5–15× faster than realtime depending on hardware.

The server auto-detects SSL certificates on startup and switches to HTTPS. The port stays the same (default 8000) — only the protocol changes. No certs = standard HTTP.

Certificate Paths (checked in order)

1. ./certs/ (project directory, recommended for CLI)
2. User data directory:
   • Windows: %APPDATA%\snappierServer-electron\certs\
   • macOS: ~/Library/Application Support/snappierServer-electron/certs/
   • Linux: ~/.config/snappierServer-electron/certs/

Required: privkey.pem and fullchain.pem

Let's Encrypt

sudo certbot certonly --standalone -d yourdomain.com

mkdir -p ./certs
sudo cp /etc/letsencrypt/live/yourdomain.com/privkey.pem ./certs/
sudo cp /etc/letsencrypt/live/yourdomain.com/fullchain.pem ./certs/
sudo chown $USER:$USER ./certs/*.pem

Reverse Proxy (Caddy)

# Caddyfile
yourdomain.com {
    reverse_proxy localhost:8000
}

caddy run

Caddy handles certificates, renewal, and HTTP-to-HTTPS redirect automatically.

Self-Signed (dev only)

mkdir -p ./certs
openssl req -x509 -newkey rsa:4096 \
  -keyout ./certs/privkey.pem \
  -out ./certs/fullchain.pem \
  -days 365 -nodes -subj "/CN=localhost"

Verify

# Check server logs:
# HTTPS: "SSL certificates found in ./certs - starting HTTPS server"
# HTTP:  "No SSL certificates found - starting HTTP server"

Certificate Reload

Certificates are read on startup only. After updating or renewing certificates, restart the server for changes to take effect.

App Connection

Enable the HTTPS/SSL toggle in Snappier IPTV settings. For self-signed certs, visit https://SERVER-IP:8000 in mobile Safari/Chrome first to accept the certificate.

• Config location: Desktop app stores config in the OS user-data directory (%APPDATA% / ~/Library/Application Support/ / ~/.config/). CLI defaults to ~/SnappierServer/config.json.
• CLI binary: The CLI is a standalone executable with Node.js bundled in. No runtime dependencies — just download and run.
• FFmpeg: Bundled on macOS/Windows (desktop app). Install separately on Linux and for all CLI installs.
• Recording format: .ts (MPEG Transport Stream). Enable remuxing to convert to .mkv for better compatibility with media players like Plex and VLC.
• Default storage: ~/SnappierServer/ (recordings, movies, series, PVR data). Override with env vars or CLI args.
• Port conflicts: If port 8000 is already in use, the server will fail to start with an EADDRINUSE error. Change the port with PORT=9000 or --port 9000.
• Firewall: Allow traffic on the configured port for cross-device access.
• VPN: The server and client must be able to reach each other over the network (same LAN, or routable via VPN).

Updating

Replace the binary or app with the new version. Your configuration, API token, and recordings are stored separately in ~/SnappierServer/ (CLI) or your OS user-data directory (desktop app) and persist across updates.

Uninstalling

• Windows: Delete the extracted folder. Remove %APPDATA%\snappierServer-electron if you want to clear config.
• macOS: Drag the app from Applications to Trash. Remove ~/Library/Application Support/snappierServer-electron for config.
• Linux: Delete the AppImage or CLI binary. Remove ~/.config/snappierServer-electron (desktop) or ~/SnappierServer (CLI) for config and data.

Desktop App vs CLI

Both share the same recording/download engine. The desktop app adds a Preferences UI, system tray with start/stop controls, a log viewer window, folder browser dialogs, and automatic port hot-reload when config changes. The CLI reads config once at startup.
