Which one is for you

Pick Viscosity if

  • Fits if you use OpenVPN on both a Mac and Windows and want a tidy client
  • Works for admins who want scripting and deployment bundles

Look elsewhere if

  • Not for you if you want a VPN service, as it has no servers
  • Skip it if you use Linux or a phone, as it runs on Mac and Windows only
  • Watch out: a license includes free updates for 1.x versions only, and upgrades are sold separately
  • Skip it if OpenVPN is not your protocol, as it supports nothing else

Pick WireGuard if

  • Fits if you are happy to run your own server and exchange keys by hand
  • Works for people building a VPN or a provider's app on top of a small protocol

Look elsewhere if

  • Skip it if you want a hosted VPN, as there are no provider servers
  • Not for you if you want sign-in, users and policy, because those need other tools
  • Too light for a team: pushing configuration to many people is outside its scope
  • Watch out: the site says the project is under heavy development
  • Watch out: the Mac and iPhone apps come from the App Store, and Android from Google Play or an APK

How we grade them

2.0GPAViscosityFair2.4GPAWireGuardFair
Value for money
A$16 once is under a year of the category's middle subscription at $5 a month, though you still pay for a VPN service.
CFree to download, but there are no provider servers, so you pay for a server of your own. Software that is only free if you host it yourself is a C.
Free plan and trial
C30-day free trial on Mac and Windows; the page does not say whether a card is needed.
AFree outright, with donations asked for. The software has no plan or cap.
Features
DIt does a narrow job, an OpenVPN client, and needs a VPN server or provider to be of any use, even with its scripting and split DNS.
CKey-based tunnels with a small codebase. It does that job fully, but it is a smaller job: key distribution and pushed configuration are outside its scope.
Ease of use
DYou import or write OpenVPN configurations and can script connections, so it needs technical know-how.
DNo rating on record, and setup is on you: keys, a server and config files, usually from a command line.
Platforms and integrations
CMac and Windows desktop only, with OpenVPN and AppleScript as its only listed links.
BWindows, Mac, Linux, iPhone and Android, though the listing names no API or integrations.

Key features

Viscosity

Connection editor
Create or edit OpenVPN connections without writing configuration by hand, including multi-factor authentication settings, with advanced commands for experts.
Full and split DNS
Send every DNS lookup to the VPN's servers, or only lookups for chosen domains.
Traffic statistics
A menu overview of connections plus a details window with a traffic graph and network and encryption information.
Scripting and automation
Control the app with AppleScript or VBScript, and run custom scripts when a connection changes state.
Obfuscation and simultaneous connections
Works with an Obfsproxy server to get past networks that block VPNs, and can hold several VPN connections open at once.
Deployment bundles
Organizations can bundle the app with preset settings and connections to hand to their users.

WireGuard

Key-based tunnels
A connection is made by exchanging public keys between peers, and each peer lists the tunnel IP addresses it is allowed to send from.
Modern cryptography
Uses the Noise protocol framework, Curve25519, ChaCha20, Poly1305, BLAKE2, SipHash24 and HKDF.
Small codebase
Designed to be short enough for one person to review, in contrast to the larger IPsec and OpenVPN codebases, the project says.
Roaming
A connection can keep working as a peer's IP address changes.
Wide platform support
The install page lists Windows, macOS, Android, iOS and many Linux and BSD distributions, plus OpenWRT.

How this page was made

  • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
  • The grades are our own, from each tool’s review or report card. The GPA is their average.
  • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
  • The differences and the answers to the questions are worked out from those listings.
