VPN

A flat-rate, no-account, cash-payable privacy VPN. There is no forever-free tier: Mullvad costs a flat €5/month with no commitment and no discounts for longer terms. Open-source apps on every platform, runs WireGuard + OpenVPN, a strict no-logging policy audited twice, and a 30-day money-back guarantee. No email or personal data required to sign up — you get a random account number.

The open-source (GPLv2) VPN protocol that powers most modern VPNs. WireGuard is not a service — it’s a fast, minimal, audited protocol you run yourself with no device or bandwidth limits. Free to self-host on any platform (Linux kernel, Windows, macOS, iOS, Android). No managed free tier; you bring your own server (or pair it with a provider like Tailscale, Mullvad, or Proton VPN).
