mullvadvpn-app

Mullvad is that. No accounts, no profiles. You get a random number as your ID, pay your money, and connect. The client app is fully open source so you can verify it does what it claims. GPL v3, written in Rust. The app supports WireGuard and OpenVPN, has a kill switch, split tunneling, and DNS leak protection. Available on Windows, macOS, Linux, Android, and iOS. The Rust codebase means the app itself is fast and resource-light.

This is NOT a free tool. Mullvad costs 5 EUR/mo (~$5.50 USD) with no discounts for longer commitments. Everyone pays the same. You can pay with cash mailed in an envelope, crypto, or card. No free tier.

The open source part is the client app. You can build it yourself and connect to Mullvad's servers, or theoretically point it at your own WireGuard server. But the value is the server network, and that's paid. Solo users who care about privacy: this is the VPN to use. Teams needing business VPN features (centralized management, SSO): look elsewhere.

The catch: no free tier means you're paying from day one. The server network is smaller than NordVPN or ExpressVPN. And 5 EUR/mo with no annual discount makes it pricier than competitors who offer $3/mo on 2-year plans. You're paying a premium for the privacy model.
