Legend
- Protocol Type: one of:
- Centralised: a single authority is used to run the service.
- Federated: multiple independent servers can join together and communicate between each other - learn more here.
- Peer-to-peer: there is no central authority and all clients connect directly to each other.
- Lifecycle indicates either an official statement on progress or a rough estimation and is one of:
- Mature: product has been released and is relatively stable.
- Beta: product is yet to release but has surpassed its Minimal Viable Product stage.
- Alpha: product is still rough around the edges and likely does not have an MVP yet.
- In Development: product is still in early development.
- Shelved: product has been delayed indefinitely.
- Active indicates whether the project is still in development or that the service is still online.
- FOSS indicates whether the project is "free and open source software" - learn more here.
- Voice indicates whether the project supports voice calls.
- Servers indicates whether the project supports creating communities or groups of channels.[note 1]
- E2EE indicates whether the project supports creating end-to-end encrypted channels.
