Servers, bandwidth, and engineers cost money. A VPN with no revenue has to cover those costs somehow, and the way it does often undermines the exact privacy you downloaded it for.
How many free VPNs make money
- Logging and selling browsing data — the opposite of what a VPN is for.
- Injecting ads or trackers into your traffic.
- Throttling speeds and limiting data to push you toward a paid tier.
- In the worst cases, bundling questionable software.
The genuine exceptions
Not all free tiers are predatory. A few reputable providers offer limited free plans as a taster of their paid product — these are funded by subscriptions, not by selling your data. The tell is simple: a trustworthy free tier comes from a company with a paid product and a published, audited no-logs policy.
When free is fine
For occasional, low-stakes use — a quick connection on a trip — a reputable free tier can be acceptable. For everyday protection, streaming, or anything you care about, a paid VPN's speed and privacy are worth the few dollars. Compare against the five things that matter.
Key takeaway
Free isn't automatically bad, but most free VPNs monetise in ways that hurt your privacy. Prefer a reputable free tier backed by a paid product, or just pay the small subscription.
