cloud-torrent

Cloud Torrent is a self-hosted web application that lets you start torrent downloads remotely on a server and stream or download the completed files via HTTP. Written in Go, it runs as a single binary across platforms and includes an embedded torrent search feature.

What cloud-torrent is

A Go-based remote torrent client that exposes a web UI for torrent management, leveraging anacrolix/torrent library for protocol support and Go's net/http for content streaming. Deployable as Docker container or standalone binary with optional TLS and basic authentication.

Quickstart

Get the cloud-torrent source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/jpillora/cloud-torrent.git2cd cloud-torrent3# follow the project's README for install & configuration

Need it deployed, integrated, or customized instead? DEV.co ships production installs.

Best use cases

Distributed content retrieval

Deploy on a VPS or always-on server to seed torrents and stream content to clients over HTTP without running a local torrent client.

Media server setup

Self-hosted alternative to cloud storage for downloading and serving media files; mobile-friendly UI enables remote access to library.

Bandwidth aggregation

Consolidate torrent activity on a high-bandwidth server instance, reducing local network load and improving download efficiency.

Implementation considerations

AGPL-3.0 license means any deployed instance accessible over a network must make source code available if modified; review legal implications before customization.
Project rewrite in progress (0.9 branch); current 0.9.4 release (Nov 2024) is stable but future API breaking changes are planned.
No built-in backup, replication, or HA features; configuration stored in local cloud-torrent.json; deploy with external volume management (Docker) for durability.
Embedded torrent search and torrent protocol implementation depend on anacrolix/torrent library; audit that library's security posture if handling untrusted torrent sources.
Single binary model simplifies deployment but limits granular privilege separation; run behind reverse proxy with rate limiting and auth if exposed to internet.

When to avoid it — and what to weigh

AGPL compliance risk — AGPL-3.0 requires source code disclosure for any network-accessible modifications. Avoid if you cannot commit to open-source reciprocal licensing or need proprietary closed-source derivatives.
Regulated content handling — Do not use if handling copyright-sensitive material or in jurisdictions with strict liability for torrent infrastructure; torrent metadata and usage are not anonymized.
High-availability requirements — Project is stable but relatively small-scale; 155 open issues and long periods between releases suggest limited production-grade redundancy and clustering support.
Enterprise integration demands — No documented LDAP, OAuth, or enterprise auth backends; basic auth only. No API versioning strategy or changelog evident for production deployments.

License & commercial use

GNU Affero General Public License v3.0 (AGPL-3.0). This is a copyleft license: any network-accessible software derived from or linking cloud-torrent must publish its complete source code. Internal-only use is permitted; public deployment or modification triggers disclosure obligations.

AGPL-3.0 is NOT a permissive license for commercial use without legal review. Commercial entities may deploy cloud-torrent unmodified, but any customization or derivative integrated with other services must comply with AGPL source disclosure. Requires lawyer review before commercial product integration.

Security considerations

Threat model analysis required: (1) Torrent sources—untrusted torrents may contain malicious metadata; validate input. (2) Basic auth only; no rate limiting, no OAuth; suitable for trusted networks, risky on public internet. (3) No input validation details provided for config or search queries; review code for injection risks. (4) Go standard library net/http is generally robust; no known major CVEs listed, but no security audit referenced. (5) Deployed instance must protect /downloads via file permissions and reverse proxy ACLs. Test in isolated environment before production.

Alternatives to consider

Transmission

Mature, cross-platform torrent client with web UI and REST API. Permissive MIT license; no AGPL constraints. Larger community and more deployment patterns documented. Lacks 'remote-friendly' design focus.

Syncthing

MPL-2.0 licensed sync engine with web UI. Decentralized, no central server required. Different use case (sync vs. torrent), but offers remote file access and self-hosted control with permissive license.

Deluge

Python-based torrent client with web UI, REST API, and plugin system. LGPL-3.0 permissive license. Larger feature set and ecosystem. Heavier resource footprint and more complex deployment than cloud-torrent.

cloud-torrent FAQ

Can I modify cloud-torrent for my business without publishing source?

No. AGPL-3.0 requires source disclosure for any network-accessible derivative. Use unmodified, or consult legal counsel and plan open-source release. Permissive-licensed alternatives (Transmission, Deluge) may be better fit.

What torrent protocol features are supported?

Not explicitly detailed in README. Depends on anacrolix/torrent library (DHT, magnet links, metadata download). Review anacrolix/torrent docs and issue tracker for specifics; protocol coverage is not guaranteed to be 100%.

Is cloud-torrent suitable for production media servers?

Suitable for single-instance self-hosted use. Lacks HA, clustering, and load-balancing primitives. No SLA or support model documented. Treat as enthusiast/SMB tool, not enterprise-grade infrastructure.

How do I secure the web UI on the internet?

Deploy behind a reverse proxy (nginx, Caddy) with TLS, rate limiting, and auth (basic auth or OAuth via proxy). Cloud-torrent's built-in basic auth is weak; do not expose directly. Use VPN or bastion host for untrusted networks.
