Our take
Unusually for a commercial VPN, the apps are open-source and independently audited, which is exactly what privacy-minded users should weight heavily, alongside a genuinely usable free tier. Switzerland’s jurisdiction and the Proton ecosystem tie-in round out the case. The honest limit is that the free plan is slower with fewer locations, and the best features sit behind a paid plan. For people who value verifiable clients over flashy extras, it’s one of the easiest VPNs to recommend.
