الوكيل مقابل VPN
Proxies and VPNs both sit between you and the internet and both can hide your real IP address — but the similarities end there. Picking the wrong one costs you speed, reliability, or the specific control your task actually needs.
What a proxy actually does
A proxy server sits between your application and the destination server and forwards requests on your behalf. The destination sees the proxy's IP address instead of yours. Proxies typically work at the level of a single application or even a single connection — a browser, a script, a scraping job — which makes them easy to rotate, assign per task, and run in parallel by the hundreds.
What a VPN actually does
A VPN (Virtual Private Network) creates an encrypted tunnel for all traffic leaving your device, at the operating system level. Every application — browser, mail client, background services — is routed through it. This is why VPNs are the default choice for general privacy on public Wi-Fi or bypassing network-level restrictions, but a poor fit for tasks that need many different IPs at once.
Side-by-side comparison
| Criteria | بروكسي | VPN |
|---|---|---|
| Scope | Per application / connection | Entire device |
| Encryption | Usually none (unless HTTPS) | Full tunnel encryption |
| Typical speed | Higher — less overhead | Lower — encryption overhead |
| Running many in parallel | Easy — built for it | Impractical |
| Typical use case | Scraping, automation, geo-testing | General browsing privacy, public Wi-Fi |
When to use which
If you need to run many parallel checks or requests, each with a different exit IP, a pool of proxies is the only practical option — this is exactly what Proxy Checker is built to validate. If you need to protect everything you do on a network you do not fully trust, a VPN is the simpler, safer default.
Either way, a proxy or VPN endpoint you have not verified is a liability: slow, unstable, or misconfigured servers can leak your real IP or silently fail. That is why every proxy is worth checking before it goes into production.
الأسئلة الشائعة
Can I use a proxy and a VPN together?
Yes. A common setup is a VPN for the whole device plus a proxy inside a specific application, such as a browser profile or a scraping tool, for more granular control.
Which one is faster?
Proxies are usually faster because they only reroute traffic for a single application and add less overhead than a full VPN tunnel.
Is a free proxy safe to use?
Free proxies vary widely in quality and trustworthiness. Always check speed, anonymity level and HTTPS support before relying on one — that is exactly what Proxy Checker is for.
