Yes it is! It’s effectively a free WireGuard (actually AmneziaWG) dVPN and mixnet, available on 5 major platforms (Android, iOS, Linux, macOS, Windows), and run by reputable scientists, cryptographers and privacy people. Worth giving it a try (and sharing your feedback with us 
) before we switch to the paid version in March!
Caveats apply depending on your use cases and threat model (no killswitch yet, no post-quantum, etc., see Nym and NymVPN - Next-gen privacy with mixnet and VPN service - #4 by marc).
Thanks
