The short version

  • Each has a real cost: Lark lark's own pricing page description states it offers a free starter pack, a Pro plan, and an Enterprise plan, and directs buyers to Contact us rather than publishing Pro/Enterprise figures on the rendered page.; 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: Lark covers Team messaging, Signal covers End-to-end encryption.
