WireGuard is rated higher (4.5 vs 3.7). WireGuard is a modern open source VPN protocol, in the Linux kernel since 5.6 (March 2020). Around 4,000 lines of kernel code vs ~70,000-100,000 for OpenVPN (500,000+ with OpenSSL) and 400,000+ for IPsec stacks. Powers modern commercial VPN tunnels such as Mullvad's recommended protocol and NordVPN's NordLynx. ZeroTier creates virtual Ethernet networks over the internet. Connect servers, VMs, and devices as if on the same LAN. Personal plan is free for 10 devices (non-commercial). SDN-based layer-2 architecture.

WireGuard
Pros
- + Free and open source — the protocol itself will never be a line item
- + Around 4,000 lines of kernel code: auditable by a single expert, minimal attack surface
- + Kernel-level performance on Linux; adopted as the underlying protocol by major commercial VPN providers
- + Dead-simple model: SSH-style key exchange, Cryptokey Routing, and automatic roaming between networks
- + Formal academic whitepaper defining the protocol and the reasoning behind each design choice
Cons
- - No vendor, no support contract, no SLA — availability is whatever your own infrastructure provides
- - Key distribution and configuration management are explicitly out of scope; multi-user setups need a control plane
- - Static key-to-IP peer table creates correlation risk on shared commercial gateways (why NordLynx adds double-NAT)
- - Unobfuscated UDP fingerprint — easily detected and blocked by restrictive networks
- - Requires operational comfort: patching, firewalling, and monitoring are all on you
ZeroTier
Pros
- + True layer-2 virtual Ethernet: broadcast and multicast work, unlike WireGuard-based overlays
- + Free Personal plan covers a 10-device homelab with no time limit
- + Native IPv6 support with RFC 4193, 6PLANE /80 delegation and public prefix routing
- + Lightweight agents (under 16 MB memory) with broad platform support including MikroTik and Docker
- + Direct peer-to-peer paths keep traffic off vendor infrastructure when NAT traversal succeeds
Cons
- - Free tier shrank to 10 devices, one network, non-commercial only; no API without a paid plan
- - No forward secrecy in its Salsa20/Poly1305 protocol, unlike WireGuard-based rivals
- - Since v1.16 the controller is non-commercial source-available; commercial self-hosting means Enterprise
- - Relayed fallback traffic is slow, and paid Premium Relays are still listed as coming soon
- - Monthly-only, non-refundable subscriptions with configuration lockout if payment lapses
