After two years of development, W4 Games is proud to announce the first beta release of W4 Cloud, our open-source backend for online and multiplayer games optimized for the Godot Engine.
W4 Cloud has been built around the same concepts as the Godot Engine: simplicity and flexibility.
As part of our commitment to open-source, we have made the initial public release available under the GNU AGPLv3 license.
Note that it seems this will only be free & open source initially, but will probably move to a paid model on release. W4 is a for-profit company, after all.
Edit: Removed some speculation, I misunderstood the “initial public release” part and assumed later releases would not be foss
Steam only works on steam while this allows full crossplay similar to Nakama or the Epic Online Services.
