What format should I paste into Nstbrowser?

host:port:username:password for HTTP and HTTPS, with socks5:// in front for SOCKS5. On the Proxies page you can add an alias at the end, for example http://host:port:user:pass:alias.

What is the difference between Saved Proxies and Saved Proxy Group in Nstbrowser?

Saved Proxies assigns one proxy to the profile. Saved Proxy Group picks a random proxy from the group each time the profile starts, which suits logged-out work but not accounts.

Does Nstbrowser match the time zone to the proxy?

Yes. It generates language and time zone from the IP and can set geolocation from the IP too; you can still adjust them by hand.

Can I change Nstbrowser proxies through the API?

Yes. The Python SDK has update_profile_proxy, which takes a proxy URL such as http://user:pass@host:port, plus batch update and reset methods.

Can team members manage proxies in Nstbrowser?

Yes, according to their permission group: creating, importing, editing, checking and exporting proxies are separate permissions.

How to add CleanProxies to Nstbrowser

In Nstbrowser, create or edit a profile, choose Custom Proxy and paste your CleanProxies line as HOST:PORT:USERNAME:PASSWORD (prefix it with socks5:// for SOCKS5); Nstbrowser parses it into the fields. Check the proxy, then save the profile.

What you need

Nstbrowser serves two crowds: multi-account teams and automation users running RPA, the SDK and CDP-driven browsers. Both need the same thing from a proxy: an IP that holds steady per profile. A dedicated CleanProxies ISP IP gives every profile a fixed US identity, and the SDK can swap it in code.

An active CleanProxies plan

Static ISP proxies for fixed US IPs, or rotating residential / mobile proxies for pools. The $4.99 trial works too.

Your credential line

From the dashboard's proxy manager: host (or IP), port, username and password. Convert lists with the proxy list formatter.

Nstbrowser ready

Nstbrowser installed and signed in.
For the SDK sample: pip install nstbrowser and an API key from your Nstbrowser account.

Which proxy fits Nstbrowser?

Both products use the same setup in Nstbrowser. What changes is how long an IP stays with you.

Static ISP Proxies

Best fit

Assign each profile a single saved ISP proxy. The dedicated US IP never changes between launches, and unlimited bandwidth and threads cover RPA runs and long automation jobs.

starting from$0.75/IP

Dedicated static IPs registered to US and Canadian ISPs. The address stays the same for as long as you hold it, with unlimited bandwidth and HTTP(S) or SOCKS5 access.

Rotating Residential Proxies

Also works

For logged-out scraping, a Saved Proxy Group of sticky residential lines gives each launch a different IP while each session holds for the length you chose. Rotating residential lines change on every request.

starting from$0.63/GB

Residential IPs in 190+ countries with country, state and city targeting. Rotate on every request or hold a sticky session for up to 90 minutes; GB never expire.

Your CleanProxies credentials

Every product connects over HTTP(S); static ISP and ISP subnet proxies also run SOCKS5 and IP whitelisting. This is what the dashboard gives you to paste into Nstbrowser.

Static ISP and ISP subnetHTTP(S)SOCKS5IP whitelist

IP:PORT:USER:PASS

One line per dedicated IP. With IP whitelisting on, the line is just IP:PORT and no password is sent.

Rotating residential and mobileHTTP(S)User:pass

HOST:PORT:USER:PASS

Generated in the proxy manager. The username carries the location and session you pick, so generate a new list to change them.

As a URL, for code and most toolshttp://USERNAME:PASSWORD@HOST:PORTsocks5://USERNAME:PASSWORD@HOST:PORT

Use http:// even for HTTPS websites; the TLS session still runs end to end. The socks5:// form is for static ISP and ISP subnet proxies.

How to set up CleanProxies in Nstbrowser

Four steps, then check the exit IP with the free proxy checker.

1
Create a profile
Open Profiles and click Create Profile. Enter a Name, choose the group and the operating system.
2
Choose Custom Proxy
In the proxy configuration, pick Custom Proxy. Local means no proxy at all, and Platform Proxy is Nstbrowser's own proxy service.
3
Paste the line
Paste HOST:PORT:USERNAME:PASSWORD for HTTP(S), or socks5://HOST:PORT:USERNAME:PASSWORD for an ISP list with SOCKS5 switched on. Nstbrowser fills the fields from it.
4
Check and save
Run the proxy check from the proxy section, then save the profile. To reuse a proxy you've saved before, pick it under Saved Proxies instead.

Nstbrowser + CleanProxiesTextPython

Keep proxies in groups on the Proxies page

Open Proxies in the left sidebar, click Create Group, then Add and paste your lines. An alias at the end of a line names the proxy:

Lines with aliasesText

http://HOST:PORT:USERNAME:PASSWORD:us-isp-01
http://HOST:PORT:USERNAME:PASSWORD:us-isp-02
socks5://HOST:PORT:USERNAME:PASSWORD:us-isp-03

Check Proxy saves each result; Clear Failed removes the dead lines in one click. Checks can run through nstbrowser, iplook or ipinfo.
Deleting a group deletes its proxies and clears them from every profile that used them.
Saved Proxy Group gives a profile a random proxy from the group at each launch. For logged-in accounts, assign one proxy with Saved Proxies instead.

Change a profile's proxy from Python

Nstbrowser SDKPython

from nstbrowser import NstbrowserClient

client = NstbrowserClient(api_key="your_api_key")

# Point an existing profile at a CleanProxies line
client.profiles.update_profile_proxy(
    profile_id="your_profile_id",
    data={"url": "http://USERNAME:PASSWORD@HOST:PORT"},
)

# Start it; the response includes the details to attach automation
print(client.browsers.start_browser(profile_id="your_profile_id"))

reset_profile_proxy removes a profile's proxy again. In the app, select several profiles, open the ... menu and choose Modify Proxy to change them in one go.

Troubleshooting Nstbrowser proxy errors

Verify your exit IP

Check Proxy stores the result with each saved proxy, and a profile's Proxy Logs show its proxy history. Nstbrowser sets language, time zone and geolocation from the IP, so after launch confirm the address on what is my IP before logging in.

Open What is my IP? through the proxy to see the address and headers a website receives, or paste up to ten lines into the free proxy checker to test connectivity, latency and exit IP.

Still stuck? Our 24/7 support team answers fast: contact us with the error and the line you used (leave the password out).

Nstbrowser error fixes

Profiles suddenly have no proxyWhy: The proxy group they used was deleted, which clears the proxy from every linked profile.Re-add the lines to a group and assign them again with Saved Proxies or Modify Proxy.
A profile's IP changes between launchesWhy: It uses a Saved Proxy Group with several proxies, so Nstbrowser picks one at random each time.Assign a single proxy under Saved Proxies.
SOCKS5 line fails the checkWhy: No socks5:// prefix, a residential line (HTTP(S) only), or SOCKS5 not switched on for that ISP list.Add the prefix and switch on SOCKS5 for the ISP list in your dashboard, or use the plain HTTP line.
The site flags a new profile anywayWhy: The same IP is shared by several profiles, or the fingerprint's timezone and language don't match the IP.Give every profile its own dedicated ISP IP and let the browser match timezone, geolocation and WebRTC to the proxy.
407 or an authentication prompt inside the profileWhy: The password was pasted with a trailing space, or the line was split in the wrong order.Paste the full HOST:PORT:USERNAME:PASSWORD line again from the dashboard.
