Configure a proxy

A proxy gives each profile its own outgoing IP address, so the sites you visit see a different location and network for every account. Santiago supports HTTP, SOCKS4 and SOCKS5 proxies, with optional username and password. This page walks you through adding one to a profile.

Why every profile needs its own proxy

Your fingerprint hides your hardware and browser identity, but it does nothing about your IP address. If ten accounts all connect from the same IP, a site can link them together no matter how unique their fingerprints are.

For account separation, pair one profile with one proxy:

• A dedicated IP per profile makes each account look like a separate person on a separate network.
• Reusing a single proxy across many profiles re-creates the exact footprint you are trying to avoid.
• The proxy location should match the rest of the profile. Santiago can read the proxy’s exit location and align timezone, locale and geolocation to it automatically.

Keep location in sync

Turn on Auto GeoIP in the profile’s fingerprint so the timezone, language and coordinates follow the proxy’s real exit IP. See Fingerprints: geolocation for how this works.

Proxy types

When you open a profile and go to the Proxy section, you choose a type. Each type expects the same details (host, port, and optional credentials) except None.

Type	When to use it
None	No proxy. The browser connects directly from your own IP. Good for quick local testing, but it gives no account separation.
HTTP	The most common proxy format from commercial providers. Works for nearly all web traffic.
SOCKS4	An older SOCKS protocol. Use it only if your provider specifically gives you SOCKS4 endpoints.
SOCKS5	A flexible SOCKS protocol that supports username/password authentication. A good default when your provider offers it.

Which one should I pick?

Use whatever type your proxy provider tells you to use. Most residential and mobile proxy plans hand you HTTP or SOCKS5 endpoints. If you are unsure, HTTP is the safest starting point.

Add a proxy to a profile

1. Open the profile you want to edit (or create a new one — see Create and edit profiles).
2. Find the Proxy section in the profile form.
3. Choose a Type: None, HTTP, SOCKS4 or SOCKS5.
4. If you picked anything other than None, fill in the connection details below.
5. Save the profile.

Connection details

For HTTP, SOCKS4 and SOCKS5 you provide the following fields:

Field	Required	Notes
Host	Yes	The proxy server address — a hostname or IP, for example gw.proxyprovider.com or 203.0.113.10. Must not be empty.
Port	Yes	The port number your provider gave you. Any whole number from 1 to 65535.
Username	No	Fill in only if your proxy uses login authentication.
Password	No	Fill in only if your proxy uses login authentication.

Leave username and password blank for proxies that authenticate by IP allowlist instead of a login.

Get the details exactly right

Host, port, username and password must match what your provider gave you, character for character. A wrong port or a stray space is the most common reason a proxy fails to connect.

When you choose None, there are no other fields to fill in, and Santiago skips all location matching — the browser simply uses your own connection.

Test before you rely on it

After saving, always confirm the proxy actually works and shows the IP and location you expect. Santiago can connect through the proxy, report the exit IP, and look up its country, city and timezone for you.

See Test a proxy and check GeoIP for the full walkthrough.

Tip

Test the proxy before you log into any important account through the profile. Launching with a dead or mislocated proxy can expose your real IP or trigger a security check on the site.
