A free VPN capped at a few gigabytes a month is one you end up switching off, which is how most free plans stop protecting anything. Proton VPN removed that limit and left it removed, and that alone puts its free plan on nearly every shortlist of VPNs worth putting on a Windows machine. The question before you download it is not whether the free tier hides a trap. It is which of the conveniences it quietly holds back you will hit first.
An unlimited free tier that Proton VPN pays for with subscriptions
The free plan has no data limit, no time limit, and no ads, and it runs the same encryption and no-logs policy as the paid tiers. People arrive asking whether a VPN can really be free, and here the answer is yes, permanently, because paying subscribers cover the free servers rather than advertisers or data brokers.
What it trades away is control. You get one connection at a time, and the app decides which country you land in from a short list of free locations, so a free account cannot appear somewhere specific on demand. Those servers are also shared with every other free user, which is where the speed complaints start.
Which Proton VPN features are free and which need a paid plan?
The split between tiers is unusual: Proton AG holds back convenience, not protection.
Protection that does not change between plans
Every plan gets the same encryption, AES-256 on OpenVPN and IKEv2 and ChaCha20 on WireGuard, plus a kill switch that cuts your connection if the tunnel drops. Windows adds a permanent kill switch that blocks traffic at all times unless the VPN is up, including during startup and shutdown. Leak protection is standard, DNS queries resolve inside the tunnel, and Smart protocol cycles through the available protocols until one connects. On networks that filter VPN traffic, Stealth disguises the tunnel as ordinary HTTPS, and alternative routing reaches the servers through other networks when they are blocked. The apps are open source.
What a paid plan adds on top
Paid tiers open the full server network across well over a hundred countries, ten simultaneous connections, and the servers that handle streaming and file sharing. NetShield filters ads, trackers, and malware domains at the DNS level. Secure Core routes traffic through a hardened server in a privacy-friendly country before it exits, which costs speed but hides the exit hop from anyone watching your network. Tor over VPN, port forwarding, and the browser extensions sit behind the same line. Recent work on Windows removed an old annoyance for paying users, since split tunneling can now run alongside the kill switch and NetShield instead of forcing a choice between them.
The line the free plan draws
The boundaries are worth reading before you install, since they are why people upgrade.
None of these are hidden, but the effect is cumulative. A free account is a fine always-on privacy layer for one machine and a poor tool for anything that depends on where the server sits.
The no-logs policy has an audit trail behind it
Proton VPN keeps no record of what you do online: no browsing history, no DNS queries, no connection metadata tying a session to a person. The company sits in Switzerland, where nothing obliges it to retain that data, and it publishes the results of repeated outside examinations of its servers and operating procedures, not an audit of the privacy policy text that some rivals settle for. Swiss courts have ordered Proton to identify users on specific servers hundreds of times, and each time the records did not exist.
Two caveats belong next to that. Account data exists, since an email address and payment details run the service, though none of it links to browsing sessions. Swiss surveillance rules are also under review, which Proton has answered by moving parts of its infrastructure out of the country. The no-logs record is strong; the jurisdiction argument is the part worth rechecking.
Windows and Linux get the fullest Proton VPN builds
Linux is the surprise among them: even free accounts get a graphical app and a command-line client, which almost no other provider bothers with. The mobile apps are simpler, and the protocol lineup has been trimmed on Apple platforms and on Android, so what appears in your settings depends on the app. Android TV, Chromebooks, and manually configured routers work too; browser extensions are paid.
Going from installed to connected on Windows takes four steps:
One thing worth knowing before it happens: when the Windows app “will not open”, the usual cause is a Proton VPN process still sitting in Task Manager from the last session, which makes Windows ignore every new click on the icon. Ending that task and relaunching fixes it far more often than reinstalling does, and an overlay or security tool holding the process open is the usual reason it got stuck there.
Proton VPN against Windscribe, PrivadoVPN, and hide.me
Windscribe’s free plan suits people who want controls: it lets you choose your location, allows connections on all your personal devices, and ships the same firewall and split-tunneling settings as its paid app. The cost is a monthly data allowance that ordinary browsing burns through quickly. PrivadoVPN also lets you pick a country and holds up better for an occasional stream, but its high-speed allowance is metered and throughput collapses once you pass it. hide.me matches the uncapped data and the single connection, from a smaller set of locations, with free speeds deliberately throttled.
Choose Proton VPN when the tunnel is meant to stay up all day on one machine and you never need to look like you are somewhere in particular. Choose Windscribe when location choice and covering several devices matter more than running out of data. Choose PrivadoVPN if streaming is the goal, and accept that no free plan does it reliably for long.
WireGuard is the default and the fastest protocol on most connections; OpenVPN is the compatibility fallback, and Stealth trades speed for getting through filtering. On paid servers the network rarely becomes the bottleneck for streaming or large downloads. On free servers congestion, not the protocol, sets your ceiling, and testers consistently measure free throughput well below the paid network. Distance compounds it: an assigned server on another continent adds latency you cannot design around. The client sits in the tray without noticeable CPU load, and the battery cost comes from keeping the tunnel up all day rather than from the app.
Worth the download for one-machine privacy, less so for streaming
Proton VPN earns its place for anyone who wants an always-on privacy layer without watching a data meter, and its free plan is a real product rather than a trial. Reach for a paid tier if you need to choose a country, cover a household, share files, or stream, and look at a rival free plan if picking your location is the point. For everyone else it is a straightforward download and one of the few free VPNs worth everyday traffic.
