What WireGuard Does Differently From OpenVPN
If you have ever opened a VPN app and seen a choice between WireGuard and OpenVPN, it can look like one more setting you are supposed to understand before you are allowed to have privacy.
The short version: both are VPN protocols. They both help create an encrypted tunnel between your device and a VPN server. OpenVPN is the older, very flexible one. WireGuard is the newer, smaller one built for speed and simplicity.
For most normal people using a VPN on a phone or laptop, that difference matters less as a technical debate and more as a daily-life question: does it connect quickly, stay connected, and avoid making the internet feel heavy?
WireGuard is much smaller
The thing people mention most about WireGuard is its size. WireGuard's Linux implementation is often described as being under 4,000 lines of code. OpenVPN is much larger and depends on a broader stack of options and libraries.
That does not automatically mean WireGuard is "secure" and OpenVPN is "insecure." OpenVPN has been around for years and has had a lot of review. But smaller code is easier to understand, easier to audit, and harder to misconfigure in weird ways.
Think of it like a simple bike lock versus a whole garage door system. The garage door system might be strong, but there are more parts to install, maintain, and get wrong.
WireGuard usually feels faster
Independent VPN tests usually find the same basic pattern: WireGuard tends to deliver higher download and upload speeds than OpenVPN, especially compared with OpenVPN over TCP. One recent benchmark from RTINGS showed WireGuard with much higher throughput than either OpenVPN TCP or UDP in its test setup.
There are a few reasons for that. WireGuard uses modern cryptography, a leaner design, and UDP only. It also has a fast handshake, which is the little setup conversation your device and the VPN server have before traffic starts moving.
That fast handshake is one reason WireGuard feels good on phones. Your phone is constantly switching between WiFi, cellular, weak signal, strong signal, screen-on, and screen-off. A VPN that reconnects quickly is less annoying.
OpenVPN still has a place
OpenVPN is not dead. It is still useful in older networks, corporate setups, routers, and situations where you need a very specific configuration. It can also run over TCP, which sometimes helps on restrictive networks that block or throttle UDP traffic.
That flexibility is the tradeoff. OpenVPN can be tuned in more ways. WireGuard intentionally removes a lot of knobs. For a network admin, knobs can be useful. For a regular person trying to protect coffee shop WiFi traffic, fewer knobs is usually better.
Battery life is a little harder to state cleanly. A faster, leaner protocol can use less CPU time, which can help. But your screen, signal strength, apps, and radio use matter too. The practical win is not "WireGuard doubles your battery." It is that WireGuard tends to connect fast and stay out of the way.
That is why 99¢ VPN uses WireGuard. Not because protocol branding matters to most people, but because a VPN you actually leave on is better than one you keep turning off because it feels slow.
If you want a simple WireGuard VPN without the usual expensive bundle, you can get 99¢ VPN for $11.88/year. One device, plain setup, no giant renewal-price game.
The bottom line: OpenVPN is the old reliable toolbox. WireGuard is the lighter everyday tool. If you just want encrypted traffic that feels normal on your phone, WireGuard is probably the one you want.
