Proxies for antidetect browsers: a dedicated IP per profile

How to connect FLEX-Traffic to an antidetect browser

1. 1
   Buy 1 GB for $1 and open FLEX-Traffic in the dashboard.

   The test gigabyte is enough to try the pool on 2–3 profiles. No whitelist needed: the proxy lets you in by username and password.

2. 2
   Create static lines, one per profile.

   Pick the country, the protocol and the static port type. Each line goes online through its own IP, and you can create up to 1,000 lines at once.

3. 3
   Paste a line into each profile.

   A line looks like host:port:login:password. Set the same proxy type in the profile as you chose when creating the lines: where to paste the proxy and which protocol to pick is covered below.

4. 4
   Match the profile to the IP.

   Set the profile's time zone, language and geolocation from the proxy IP, and switch WebRTC to replacement mode. That way the site sees neither your real address nor a mismatch with the country.

5. 5
   Turn on traffic auto-purchase.

   The dashboard has a traffic auto-purchase switch: when less than 1 GB is left, it buys the volume you set from your balance. One account balance covers all pools. Keep funds on it, and the profiles will not lose connection mid-session.

With dozens of profiles, handing out lines by hand takes a while. The script gives each profile its own line and remembers the choice between runs: new profiles get free lines, old ones keep theirs. Put the lines from the dashboard into flex_lines.txt, the profile names into profiles.txt, and set PROTOCOL to the protocol you chose when creating the lines.

Python 3.9+Nothing to install: the standard library is enough.

        if not free:
            raise SystemExit(f"Not enough lines: {len(profiles)} profiles, {len(lines)} lines")
        assigned[name] = free.pop(0)

with open(STATE_FILE, "w", encoding="utf-8") as f:
    json.dump(assigned, f, indent=1)

    writer = csv.writer(out)
    writer.writerow(["name", "type", "host", "port", "login", "password"])
    for name in profiles:
        writer.writerow([name, PROTOCOL, *assigned[name].split(":")])
moved = sum(saved.get(name) != assigned[name] for name in profiles)
print(f"{len(profiles)} profiles, {moved} got a new line, spare lines: {len(free)} -> {OUT_FILE}")
