Why eMule Qt?

eMule Qt is a free, open-source peer-to-peer file sharing client for the ED2K and Kademlia networks — rebuilt from the ground up with Qt 6 and modern C++23.

Download

Cross-platform. Fully compatible with the existing eMule network. Based on the original eMule client.

• ED2K & Kademlia — Server-based and decentralized DHT networks for maximum source availability
• Cross-Platform — Runs natively on Windows, macOS, and Linux
• Daemon/GUI Split — Headless daemon (emulecored) + Qt GUI (emuleqt), connect remotely or run on a server
• IPv6 — Dual-stack ED2K across clients, servers, source exchange and links, so IPv6-only and CGNAT users take part as full peers
• Encrypted HTTP Cache — When several peers want the same part, upload it once and hand the rest an encrypted URL
• Automatic Port Mapping — PCP, NAT-PMP and UPnP raced at startup, graded on whether your exact port was really granted
• Protocol Obfuscation — TCP/UDP encryption enabled by default
• AICH Verification — Chunk-level integrity checks with automatic corruption recovery
• Queue & Credit System — The proven eMule reward system for fair sharing
• Built-in Web Server & REST API — Remote control from a browser, plus a JSON API and CLI for scripts
• Advanced Search — Expression-based queries across multiple networks
• IRC Chat & Messages — Built-in IRC client and peer-to-peer messaging
• IP Filtering — Dynamic blocklists with automatic updates
• Media & Archive Preview — Preview video files and browse archives before download completes
• Statistics — Real-time bandwidth graphs, connection metrics, and Kademlia visualization
• Nothing Is Lost on Restart — Download sources, upload-queue positions and statistics history all survive a restart
• Internationalization — 9 languages out of the box

Roadmap

• NAT Traversal — Many users sit behind NATs and firewalls that prevent incoming connections, limiting them to “Low ID” status and reduced source availability. We plan to implement NAT traversal based on the work by DavidXanatos.
• QUIC Transport — We are exploring QUIC (the transport protocol behind HTTP/3) as an alternative to TCP for peer connections. QUIC offers built-in encryption, multiplexed streams without head-of-line blocking, faster connection establishment (0-RTT), and better performance on lossy networks. It also traverses NATs more gracefully than TCP since it runs over UDP. This will allow previous “Low ID” clients to connect with each other seamlessly without relay/buddy.
