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.

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

Download the latest Gopeed client for Windows.

Gopeed 2.0.0 is currently in public beta, introducing a redesigned interface, a native communication architecture that connects desktop and mobile clients directly to the Go core through FFI, a more consistent cross-platform experience, improved task management, more flexible API support, and MCP-based AI agent integration. Some features may still be incomplete or unstable, so please try it and report any issues you encounter.

• Download Gopeed 2.0.0 Beta 3

Once the features and stability meet our release standards, we will publish the official Gopeed 2.0.0 release. Beta users will be able to upgrade directly to the final release, while existing stable users will not be automatically moved onto the beta channel.

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

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

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
