Open source

gravel

GRVL runs gravel, an open-source framework for running game servers across many games with linked identities, cross-game stats and moderation. Its code, its design records and its issue tracker are public.

The license

gravel is licensed under the Apache License 2.0. You can run it, change it and redistribute it, for any purpose, with attribution and the license kept intact.

How GRVL and gravel relate

• GRVL is the hosted service, run by MKZ Systems, LLC.
• gravel is the framework. It is a project of its own, with its own repository and releases.
• Both are built by the same people.
• Features land in gravel first. GRVL runs released versions of gravel, and nothing that is not in the public repository.

Self-host instead

If you would rather run it yourself, you can. The repository has the install guide, the release images and the configuration reference. You get the same hub, the same bot and the same data model that GRVL hosts, and you take on the provisioning, backups, monitoring and updates yourself.

Moving between the two works in both directions. A GRVL hub exports to a form a self-hosted gravel can load, and a self-hosted gravel can move onto GRVL.
