TeamViewer is a mature product, but its commercial-use detection frequently blocks personal and small-business users. Licenses start at hundreds of dollars per year, and all traffic routes through TeamViewer's cloud.
RelayHold has no device limits and no commercial-use popups, and collects no telemetry about how you use it.
