The short version

  • Only Signal has a free tier, so it costs nothing to try first.
  • Each has a real cost: Signal signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account; TeamViewer pricing page gates all figures behind plan selection with no listed price for its Teams and Tensor Enterprise tiers, which are described as a fully customized license requiring sales contact
