Example Trackers
When to Use UDP
Ideal for:
- General torrenting (best performance)
- Home networks and personal use
- VPN connections
- High-speed connections
- Low-latency requirements
Advantages
- Lowest latency (no connection overhead)
- Minimal bandwidth usage for announces
- Faster peer discovery
- Better for high-volume seeding
- Stateless protocol (no connection tracking)
Port Information
Common UDP tracker ports:6969- Most common tracker port1337- Popular alternative port80- HTTP port (bypasses some filters)451- Alternative port9337- High port range

Example Trackers
When to Use HTTP
Ideal for:
- Networks that block UDP
- Behind HTTP proxies
- Corporate or school networks
- Legacy systems
- Maximum compatibility needs
Advantages
- Works through HTTP proxies
- Passes most firewalls
- Easier to debug (standard HTTP protocol)
- Connection-oriented (more reliable)
- Can use authentication if needed
Disadvantages
- Higher latency than UDP
- More bandwidth overhead (HTTP headers)
- Connection establishment overhead
- May require keep-alive connections

Example Trackers
When to Use HTTPS
Ideal for:
- Privacy-conscious users
- ISPs that throttle BitTorrent
- Deep packet inspection networks
- Countries with internet censorship
- Corporate networks that block P2P
- Combining with VPN for maximum privacy
Advantages
- Encrypted tracker communication
- Hides tracker URLs from ISP
- Looks like regular HTTPS traffic
- Harder to block than plain BitTorrent
- Certificate-based authentication
Privacy Considerations
HTTPS trackers only encrypt tracker communication. The actual torrent data transfer is still unencrypted unless you use a VPN or other encryption method.
- Which tracker you’re contacting
- What torrent you’re downloading
- Your peer ID and client info (from network observers)
- Your IP address (visible to tracker)
- Peer-to-peer connections (still unencrypted)
- DHT traffic

Available Trackers
When to Use WebSocket
Required for:
- Web-based BitTorrent clients
- WebTorrent Desktop
- Browser extensions
- Instant.io and similar services
- Cross-platform web apps
Compatible Clients
- WebTorrent Desktop - Desktop client with WebSocket support
- Instant.io - Browser-based torrent streaming
- BitTorrent Web - Official web client
- Any web app using webtorrent library
Traditional BitTorrent clients (qBittorrent, Transmission, Deluge, etc.) do not support WebSocket trackers. These are exclusively for WebTorrent-compatible clients.
Protocol Details
ws://- Unencrypted WebSocket (port 7072)wss://- Encrypted WebSocket over TLS (port 7073)
Limitations
- Very few public WebSocket trackers exist
- Only WebTorrent clients can connect
- Not compatible with traditional BitTorrent clients
- Limited to web browser capabilities
- Higher overhead than UDP/HTTP
Protocol Comparison
Performance Comparison
| Protocol | Speed | Overhead | Compatibility | Firewall | Privacy |
|---|---|---|---|---|---|
| UDP | Fastest | Minimal | Medium | Often blocked | Low |
| HTTP | Medium | Medium | Excellent | Rarely blocked | Low |
| HTTPS | Medium | High | Good | Rarely blocked | High |
| WebSocket | Medium | High | Limited | Rarely blocked | Medium |
Use Case Decision Matrix
Recommendation by Scenario
- Home User
- Corporate Network
- Public WiFi
- Web Application
Recommended: UDPBest performance and lowest overhead for unrestricted networks.
Combining Multiple Protocols
Optimal Combination
- Fast UDP connections when available
- HTTP fallback when UDP is blocked
- Near-complete coverage without WebSocket clutter
