Spec support

Clients × features

Which client supports which feature, and the Matrix Spec Changes each feature rests on. Every cell is an AI agent's reading of the client's docs or code, not checked by a person; it links to its source where there is one.

The features and their MSCs

Clients don't list the MSCs they implement the way servers advertise them, so this page uses the features the agent looked for in each client. Features with no MSC are older core spec or purely client-side.

Feature support by client

Clients are sorted by how many of the 24 features were found. 77 clients have at least one answer; 18 more, with nothing found yet, are folded below. A low count usually means the client is small or its docs don't say, not that the features are missing.
