The short version

  • Each has a real cost: Replicate private model deployments are billed for all the time instances are online, including setup and idle time, not only for processing; 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: Replicate covers Model hosting, Signal covers End-to-end encryption.
