Opera is known for its "free built-in VPN". Technically this feature is not a VPN but an encrypted proxy limited to the browser: it routes the traffic of Opera tabs only and does not affect other applications on the operating system. Knowing the difference is the first step to choosing the right tool.
The free feature is a quick fix; for targeted work, use residential or ISP proxy is required.
Setting Up a Proxy in Opera
Opera is Chromium-based as well and uses the system proxy by default. Menu → Settings → Advanced → System → the "Open your computer's proxy settings" link takes you to the operating system. There are two ways to set a browser-specific proxy:
- Shortcut flag:
--proxy-server="http=1.2.3.4:8080"and for a separate profile,--user-data-dir. - Extension: Opera supports Chrome Web Store extensions through the "Install Chrome Extensions" add-on; that is how proxy managers are installed.
What Is Different in Opera GX
Opera GX, the gamer edition, adds two extra features at the network layer: a bandwidth limiter and GX Corner requests. While the bandwidth limiter is on, downloads going through the proxy can be slower than expected, so turn that limit off before you blame the proxy. Game clients (Steam, Epic) run outside the browser and are therefore unaffected by Opera GX settings — those need client-side configuration is required.
Leak Check
The bottom two arrows travel outside the proxy. WebRTC and DNS tests before you declare "my IP is hidden".
Which Level Do You Need?
Most users stop at L1 and never reach the consistency L3 provides. Bot protections measure exactly that inconsistency.
Verification
Once the setting is in place, open My IP Address . The address shown should be the proxy's. Then run The anonymity test : if the result is "Elite", the headers do not reveal that you are using a proxy.
