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.
• E2EE indicates whether the project supports creating end-to-end encrypted channels.
