Free VPNs are tempting, but the old rule still applies: if you are not paying for the product, you may be the product. That said, a handful of reputable free tiers are genuinely usable for light everyday browsing.

• Watch the data policy: Legit free VPNs publish a clear no-logs policy audited by a third party. If the privacy policy is vague, walk away.
• Check the bandwidth cap: Most free plans limit you to 500MB–10GB per month, which is fine for email and news but not for streaming.
• Avoid ad-injected clients: Some free apps monetize by injecting ads or selling browsing data to brokers.
• Confirm kill-switch and encryption: Even a free tier should offer AES-256 and a basic kill-switch.
• Best use case: Public Wi-Fi, quick geo-unblocking, and casual browsing — not banking or torrenting.

Verdict: A well-known free VPN is acceptable for casual, low-risk browsing, but pay a few dollars a month if privacy or streaming quality actually matters to you.
