P2P virtual LAN for gaming over the internet. Create lobbies, invite friends, and play any LAN-enabled game together.
- Download the installer from peerden.io for your platform (Windows or macOS).
- Install and run PeerDen. On first launch, Windows may show a security prompt—click "More info" then "Run anyway".
- Create an account by clicking Account in the top-right and signing up.
- Join or create a lobby in the Community tab. Browse public rooms or make your own.
- Launch your game and select LAN multiplayer. The game will use the virtual LAN adapter automatically.
For help, visit the forums.
Consider supporting me on Ko-fi if PeerDen is useful to you.
- CMake 3.20+
- C++17 compiler (Visual Studio 2022 on Windows, GCC/Clang on macOS/Linux)
- Python 3.x (for icon conversion during build)
- OpenSSL 3.x (optional, for TLS coord server; tested with OpenSSL-Win64 from slproweb.com)
- Download
wintun.dllfrom wintun.net and place it in the project root. - Build:
mkdir build
cd build
cmake .. -G "Visual Studio 17 2022" -A x64 -DOPENSSL_ROOT_DIR="C:\Program Files\OpenSSL-Win64"
cmake --build . --config ReleaseOutput: build\Release\peerdden.exe (with wintun.dll and OpenSSL DLLs copied alongside). The installer bundles these—end users don't need to install OpenSSL.
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build .Output: build/peerdden
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release

The coordination and API server remain private for multiple reasons, but mainly because it's a bit concerning exposing infra code to the public. I am open to privately exchanging various parts, but it will never be fully released (atleast while PeerDen is up and running).
