Frequently asked questions
Which headers matter for scraping?
user-agent, accept, and accept-language are the main fingerprints sites check. Client hints (sec-ch-ua*) also leak browser and platform details.
Does a proxy change my headers?
A transparent proxy can add forwarding headers like x-forwarded-for. PinguProxy endpoints pass your request through, so what you set is what arrives.
Can I see headers from another device?
No — the checker reads the headers of the request that loaded it. To test another client, open the page from that client.
