WireGuard is rated higher (4.5 vs 4.1). 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. Tailscale creates a private WireGuard mesh between all your servers and devices with zero config. Works through firewalls and NAT. Free Personal plan for non-commercial use: up to 6 users with unlimited user devices.

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
Tailscale
Pros
- + Near-zero-config WireGuard mesh: devices connect peer-to-peer through NAT with no firewall surgery
- + Free forever for non-commercial use (up to 6 users, unlimited user devices)
- + Seat-based billing is predictable; invited-but-inactive users do not occupy seats
- + Full IPv6 support inside the tailnet plus IPv4/IPv6 interoperability via relays
- + Open-source clients; self-hostable control plane (Headscale) exists for the trust-constrained
Cons
- - Proprietary hosted control plane coordinates key exchange and sees network metadata
- - Not a privacy VPN — anonymous internet exit is an add-on or your own exit node
- - SLA-backed support is a paid add-on package on every plan, including Premium
- - Tagged-resource and ephemeral-minute meters can raise the bill for Kubernetes-heavy fleets
- - Seat overage auto-charges and is not refunded when seats are reduced afterwards
