The short version

  • Each has a real cost: GitHub acquired by Microsoft in 2018, reducing pure independence despite operational autonomy; 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: GitHub covers Git repositories, Signal covers End-to-end encryption.
  • Prices and features above were last checked on 30 August 2026.
