🚀 Introduction

Gopeed (short for Go Speed) is a fast, modern, free, and open-source download manager built with Go and Flutter. It supports HTTP, HTTPS, BitTorrent, magnet links, and ed2k on desktop, mobile, and the web.

Beyond core download management, Gopeed offers browser integration, JavaScript extensions, a REST API, a CLI, and a self-hosted web UI for customization and automation.

✨ Features

• ⚡ High-speed downloads — combine concurrent tasks, multi-connection HTTP transfers, and peer-to-peer BitTorrent downloads to make the most of your bandwidth.
• 🧲 Multiple protocols — download HTTP/HTTPS files, torrents, magnet links, and ed2k resources from a single app.
• 🌱 Full-featured BitTorrent — use DHT peer discovery, uTP transport, Web Seeds, selective file downloads, tracker management, peer and piece statistics, and ratio- or time-based seeding limits.
• 📋 Flexible task management — pause, resume, retry, run batch operations, search, filter by status, organize with categories, and recover tasks after a restart.
• 🪶 Lightweight native experience — the main interface is rendered natively with Flutter. No Electron. No WebView shell. Enjoy a smaller footprint, lower overhead, and responsive performance.

🤖 AI Integration

Connect Gopeed to an AI agent and manage downloads with natural language. For example, you can say:

Download the latest Gopeed client for Windows.

| Tool | Description | | --- | --- | | resolve_task | Resolve a download URL or URI and return its resource metadata and files before creating a task. | | create_task | Create and start a task from a resolved resource ID or a direct download request. | | list_tasks | List tasks, optionally filtering them by ID or status. | | get_task | Get the request, resource, options, and current progress for one task. | | get_task_status | Get lightweight runtime status and per-file progress for one task. | | get_task_stats | Get protocol-specific statistics, including HTTP connections or BitTorrent peers and seeding data. | | pause_task | Pause a task. | | continue_task | Continue a paused or failed task. | | delete_task | Delete a task, optionally deleting its downloaded files. |

🏗️ Build

Desktop

Set up Flutter desktop development using the official Flutter desktop guide, and make sure a working C toolchain is available for cgo. Then run the commands for your platform.

Commands:

• Windows

go build -tags nosqlite -ldflags="-w -s" -buildmode=c-shared -o ui/flutter/windows/libgopeed.dll github.com/GopeedLab/gopeed/bind/desktop
cd ui/flutter
flutter build windows

• macOS

go build -tags nosqlite -ldflags="-w -s" -buildmode=c-shared -o ui/flutter/macos/Frameworks/libgopeed.dylib github.com/GopeedLab/gopeed/bind/desktop
cd ui/flutter
flutter build macos

• Linux

go build -tags nosqlite -ldflags="-w -s" -buildmode=c-shared -o ui/flutter/linux/bundle/lib/libgopeed.so github.com/GopeedLab/gopeed/bind/desktop
cd ui/flutter
flutter build linux

Mobile

Mobile builds also require a working cgo toolchain. Install and initialize gomobile:

go install golang.org/x/mobile/cmd/gomobile@latest
go get golang.org/x/mobile/bind
gomobile init

Commands:

• Android

gomobile bind -tags nosqlite -ldflags="-w -s -checklinkname=0" -o ui/flutter/android/app/libs/libgopeed.aar -target=android -androidapi 21 -javapkg="com.gopeed" github.com/GopeedLab/gopeed/bind/mobile
cd ui/flutter
flutter build apk

• iOS

gomobile bind -tags nosqlite -ldflags="-w -s" -o ui/flutter/ios/Frameworks/Libgopeed.xcframework -target=ios github.com/GopeedLab/gopeed/bind/mobile
cd ui/flutter
flutter build ios --no-codesign

Web

Build the web app and server:

cd ui/flutter
flutter build web
cd ../../
rm -rf cmd/web/dist
cp -r ui/flutter/build/web cmd/web/dist
go build -tags nosqlite,web -ldflags="-s -w" -o bin/ github.com/GopeedLab/gopeed/cmd/web
