Grapple is designed to be a simple network layer, allowing the addition of multiplayer features to a game (or other application) for as little as a dozen lines of code. However it is also fully featured, so if you want more from your networking, you can have it.

While it hasn't seen a release in a while, I am back to actively developing Grapple, and there is likely to be a release some time in 2015. In the last month I've added a port of the client to Javascript to allow web games to interact with desktop games. I'll be adding in IOS and Android ports soon, and finally, there will at last be a complete set of manpages!
