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
OP speculation. I don’t see them closing it off after an open source release, under AGPL, and linking self-hosting as an alternative on their cloud offer page.
