  • Server-based Messengersystems (“condition”) need appropriate servers for usage - e.g. for contact list, message forwarding, groups or chat room management.
  • Server-supported Messengersystems (“possibility”) basically work without servers - however, servers can be used for special functions (like buffering of messages).
  • Serverless Messenger systems (“abandonment”) are completely decentralized and organized without special (additional) servers.



The Echo protocol is used by Goldbug (desktop client) or Smoke (Android client), for example, and is the main component of the “Comparison of the big 7 (open source) messenger systems”. The project is entirely volunteer-driven and is not paid for by third parties.

In a nutshell: Very interesting, comprehensive, coherent. Unfortunately, however, many special and technical terms; many abstract and also strange designations in the explanations (molecules, …); seems confusing and complicated for nominal users at first sight. So far no contact to German contact person possible / no German forum.

  • decentralization: direct/mesh (P2P, no separate servers)
  • positive: some anonymity
  • positive: german user manual
  • negative: NO german project page

The protocol “SecureScuttlebut /SSB (short: Scuttlebutt)” has a likewise very interesting approach and also relies on decentralization.

  • Decentralization: direct (P2P, no separate servers required)
  • positive: some anonymity
  • positive: ingenious concept (specialized in offline functionality)
  • positive: built-in support for TOR
  • negative: NO german project page/help
  • negative: in the beginning you have to download very large amounts of data
  • negative: maximum of 7 participants in “closed groups”
