Proxy vs VPN: What's the Difference and Which Do You Need?
Both proxies and VPNs sit between you and the internet, and both can hide your real IP address from the sites you visit. That’s usually where the similarity ends — the two exist to solve different problems.
How a proxy works
A proxy server forwards your requests on your behalf. The site you’re visiting sees the proxy’s IP address instead of yours, but the proxy typically operates at the application level — most often for HTTP/HTTPS traffic, and usually only for the specific app or browser you’ve pointed at it. Other traffic from your device (email, other apps) doesn’t automatically go through it.
Proxies are usually managed per-connection or per-app, which makes them well suited to running many parallel sessions — something a single VPN connection isn’t built for.
How a VPN works
A VPN encrypts your entire device’s traffic and routes it through a remote server. Every app on your device — not just your browser — goes through the tunnel. The encryption layer also protects your traffic from your ISP or anyone on the same local network, which a plain proxy does not do.
Where they differ in practice
| Proxy | VPN | |
|---|---|---|
| Scope | Usually per-app/browser | Entire device |
| Encryption | Not always | Always |
| Speed at scale | Runs many parallel IPs easily | One connection at a time |
| Typical use | Web scraping, ad verification, geo-testing at scale | General privacy, public Wi-Fi, streaming |
When you actually need a proxy
- Web scraping and data collection, where you need many different IP addresses in parallel to avoid rate limits or blocks.
- Ad verification and rank tracking, where you need to see a page as it appears from many specific locations at once.
- Automating multiple accounts or sessions, where each session needs its own distinct IP.
When a VPN is the better fit
- General browsing privacy, especially on public Wi-Fi.
- Encrypting all your device’s traffic, not just one browser.
- Simplicity — one app, one toggle, protects everything.
Not sure which one you’re actually using right now?
If you want to see exactly what a site sees when you connect, check our What’s My IP tool — it shows your current public IP and its approximate location. If you’re specifically worried about a VPN or proxy leaking your real IP through your browser, run our Privacy & Browser Leak Checker, which tests for WebRTC leaks that can bypass both proxies and VPNs at the browser level.
