The short version

  • Only Signal has a free tier, so it costs nothing to try first.
  • Each has a real cost: PlanetScale eBS High Availability requires 3-node configuration with replication overhead; Signal signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account
  • They diverge on capability: PlanetScale covers Database Branching, Signal covers End-to-end encryption.
