aMule

aMule is a free, GPL-licensed peer-to-peer client for the eD2k and Kademlia networks. It is best suited to users who still rely on those networks, especially administrators running a server, NAS, or VPS without a desktop. Its search, integrity, and remote-management controls are substantial, but network setup can determine whether it performs well enough for everyday use.

Overview

aMule connects to eD2k and Kademlia simultaneously and remains wire-compatible with eMule and other *Mule clients. That makes it a focused choice for an established eD2k/Kademlia library, rather than a broad replacement for a BitTorrent-oriented workflow. The GPL-2.0 software is free, with no telemetry and no advertisements.

Search spans both network types. Filters for file type, size, and availability, together with AND, OR, and NOT operators, are useful when broad network results need narrowing. ICH and AICH detect and repair corrupted download chunks, while re-hashing shared files provides an additional integrity check. These safeguards matter for large or long-lived collections, although they cannot compensate for poor connectivity.

Key features

Transfer and connection controls

Hard upload and download limits, a cap on simultaneous upload clients, and per-slot bandwidth targets let users protect other traffic from a busy client. IP filtering, cryptographic secure user identification, and SOCKS4, SOCKS5, or HTTP proxy support add ways to manage exposure and routing. Network-interface binding is available for most supported systems, but not on BSD.

Remote operation

The amuled daemon runs without a graphical display, making aMule practical on servers, NAS devices, and VPS instances. A native remote GUI, REST API, browser Web UI, command-line tool, and legacy WebUI cover both scripted administration and occasional browser access. Remote interfaces encrypt their connection to the core; new installations accept connections only locally, and failed logins are throttled. Those defaults provide a sensible starting point, but remote access still requires deliberate configuration.

Desktop integration

aMule can register to open ed2k:// and magnet links and .emulecollection files. Magnet support is limited to eD2k-compatible links, so users expecting broad magnet compatibility should look elsewhere.

Pricing

aMule — free. The plan is GPL-2.0 licensed, includes no telemetry and no advertisements, and has no trial because the product is already free. There are no paid tiers, seat charges, renewal terms, or stated transfer quotas. It fits individuals who want the complete client without subscription costs; organizations should consider the GPL licensing terms before deploying it commercially.

Platforms

aMule supports Windows, macOS, Linux, web, API, and self-hosted deployments. Published packages include Windows 10/11 x64 and ARM64, macOS 11.0 or later for Apple Silicon and Intel, and Linux x64 or ARM64 with glibc 2.35 or later. Linux static server builds are headless and include amuled, amuleapi, and amulecmd without shared-library dependencies, which simplifies server installation.

Who it's for

Choose aMule if your files and peers are on eD2k or Kademlia, you need detailed search and upload controls, or you want to operate a headless service remotely. It also suits privacy-conscious users who need proxy support, filtering, or interface binding. It is a weaker fit for users seeking a general torrent client, broad magnet handling, or a setup that works without network administration: the documentation warns that blocked ports create a Low ID, greatly reducing performance, and that the ports must be opened and forwarded.

Pros and cons

• Pros: simultaneous eD2k and Kademlia access; compatible with eMule-family clients; precise search operators and filters; ICH/AICH repair and re-hashing; headless daemon plus several remote-control methods; encrypted remote interfaces with throttled failed logins; no telemetry or advertising.
• Cons: performance can fall sharply behind blocked ports and requires port forwarding; magnet handling is restricted to eD2k-compatible links; interface binding is unavailable on BSD; Linux packages require glibc 2.35 or later.

Alternatives

For device-to-device transfers across mobile and desktop platforms, consider Feem; its free plan supports unlimited transfers, while Feem Pro for iOS costs $4.99 a year and is manually renewed. Choose TorrServer instead for a GPL-3.0 self-hosted torrent streaming server. BiglyBT is a free option when you want a BitTorrent client across Android, Linux, macOS, web, and Windows.

BitComet is free for private, personal, non-commercial use. Resilio Sync offers a free personal, non-commercial license with no expiration date, but requires a license to activate. Deluge is a free, open-source BitTorrent client with API, web, and self-hosted options. FrostWire is a free open-source project for Android, Linux, macOS, and Windows. JSTorrent is a free, open-source, multi-platform project.

Verdict

aMule is the right choice for users committed to eD2k and Kademlia who value robust search, corruption repair, bandwidth controls, and remote or headless operation. Its zero price and broad administration options are compelling. Look elsewhere if you need mainstream torrent and magnet compatibility or cannot open and forward the required ports, since that network constraint can outweigh the client’s otherwise strong feature set.
