The Arbiter - Group Management for Permissioned Spaces and Beyond

The Case For Universal Login and "Off-Protocol" Services

For the last year, we have been working on Roomy with a clear integration to the ATProtocol. At the same time, we've also had a distinctly "off-protocol" strategy for data handling: we don't store Roomy's canonical data on the ATProto PDS. The reason for this is that the PDS because has shortcomings, such as a lack of private data, that make it unsuitable for Roomy's needs.
