Running your own VPN on a VPS gives you a private, dedicated exit IP that no commercial VPN shares. The two protocols worth considering are WireGuard and OpenVPN. WireGuard is a modern, minimal protocol built for speed; OpenVPN is the mature, endlessly configurable veteran. Here is how they compare when you host them yourself.
WireGuard vs OpenVPN at a glance
| Feature | WireGuard | OpenVPN |
|---|---|---|
| Codebase size | About 4,000 lines | Over 100,000 lines |
| Cryptography | Fixed modern (ChaCha20, Curve25519, BLAKE2s) | Configurable (OpenSSL, many ciphers) |
| Transport | UDP only | UDP or TCP |
| Speed and throughput | Higher | Lower |
| Latency | Lower | Higher |
| Linux integration | In-kernel (needs kernel module) | Userspace |
| Censorship resistance | Detectable (fixed handshake) | Can hide on TCP 443 with obfuscation |
| Configuration | Simple key pairs | Certificates and PKI, more complex |
| Roaming and reconnection | Seamless | Slower to reconnect |
| Default port | 51820/UDP | 1194/UDP (or 443) |
| Best for | Speed, simplicity, modern setups | Compatibility and censorship bypass |
Speed
WireGuard is the clear performance winner. Its tiny codebase runs inside the Linux kernel and uses fast modern ciphers, so it delivers higher throughput, lower latency and quicker reconnections - especially noticeable on mobile links that change networks. OpenVPN runs in userspace and carries more overhead, which caps its top speed.
Security
Both are secure when configured correctly. WireGuard's advantage is its minimal attack surface: about 4,000 lines of code are far easier to audit than OpenVPN's 100,000-plus, and its cryptography is fixed to strong modern primitives with no room for weak-cipher misconfiguration. OpenVPN's flexibility is a double-edged sword - powerful, but you must choose sane ciphers and settings yourself.
Censorship resistance
This is where OpenVPN still leads. Because it can run over TCP on port 443 and be wrapped in obfuscation layers, OpenVPN traffic can blend in with normal HTTPS and slip past restrictive firewalls. WireGuard's handshake has a recognizable signature and uses UDP, so it is easier to detect and block on aggressive networks unless you add extra tooling.
Setup and the kernel requirement
WireGuard is far simpler to set up: generate a key pair for each peer, list them in a short config file and start the interface. OpenVPN requires building a certificate authority and issuing certificates, which is more work but also more granular.
One practical requirement: WireGuard runs as a kernel module on Linux, so your VPS must allow loading it. That is standard on a KVM VPS with its own kernel, such as every INET.WS plan, but not on lightweight container VPS types that share the host kernel.
Which one should you choose?
- Choose WireGuard for the fastest, simplest, most modern personal or site-to-site VPN - the right default for most people.
- Choose OpenVPN when you need to bypass censorship by hiding on TCP 443, or need broad compatibility with older clients and appliances.
Both run perfectly on an INET.WS KVM VPS, which provides the dedicated kernel WireGuard needs and a choice of 14 locations for the exit IP closest to you.
