The short answer
XProxy connects Android phones to one machine over USB and serves the proxies from that machine. That single design choice is both its best feature and its only hard limit. It removes a network hop, so latency is hard to beat and nobody else sits in your data path. It also means every phone you own has to be within cable reach of one box in one building.
So the useful question isn't which tool has more features. It's whether you're ever going to need an IP somewhere you aren't. If the answer is no, most reasons to switch evaporate. If it's yes, you'll hit the wall no matter how good the software is.
One thing worth clearing up, because two different products share this name. This page is about XProxy from xproxy.io, the software that runs a 4G and 5G mobile proxy farm off a USB rack of Android handsets. It isn't about X-Proxy, the old Windows VPN client. If you came here looking for a way to hide your own browsing, nothing below will help you.
What the alternatives trade away
| Model | Examples | What it buys | What it costs |
|---|---|---|---|
| USB tethered, local first | XProxy | Shortest path, full control, no third party in the data path | Every phone lives within cable reach of one machine, so a second location means a second site and someone to staff it. |
| Self-hosted dashboard, network attached | Proxidize | You still own the software and the box, with less cabling | You keep the operational burden. Upgrades, backups and the failed reboot are all still yours. |
| Phone app dialling out to a relay | iProxy, PocketProxy | Phones can sit anywhere with signal, including someone else's flat | You depend on a relay you don't run, so their outage is your outage and you can't fix it yourself. |
| Rent finished IPs | SOAX, IPRoyal, Coronium | Nothing to build, nothing to maintain, live the same day | The per-IP cost never stops, and you're one of several tenants unless you pay for a dedicated port. |
We build the third row, so weigh this page accordingly. The row we'd push you toward if your phones are already sitting in one room and working is the one you're on, because migrating a working rig to solve a problem you don't have yet is a bad trade at any price.
The failure modes nobody mentions in the thread
Tethered rigs fail in physical ways, and the symptoms look like software bugs. Cheap USB hubs are the single most common cause of devices that disappear and come back, because a port that can charge a phone isn't necessarily a port that can hold a stable data connection while charging it. Heat is the second: phones packed together with no airflow throttle themselves, and a throttled phone drops connections without reporting anything useful.
Dial-out models trade those for a different set. You inherit somebody else's uptime, you can't inspect the relay, and a change on their side can reach your fleet without warning. The honest framing is that you're choosing which category of problem you'd rather debug, not escaping problems.
One failure is common to all of them, and it catches everyone once. Android suspends background apps to save battery, so a proxy that ran fine all day stops answering overnight. Turn off battery optimisation for the app, then check whether your handset brand stacks a second power saver on top of Android's, because many do and the two are configured separately.
You probably don't need to switch
If your rig is stable and your customers are in your region, the honest recommendation is to leave it alone. Most complaints that send people looking for alternatives are hub, heat or battery problems, and all three follow you to the next tool because none of them live in the software.
Keep the cable
- All your phones are in one room and you plan to keep them there
- Latency is the number your customers complain about first
- You have a policy or a client requirement that no third party sits in the data path
- You already own the machine and the powered hubs, which is most of the setup cost
Time to move
- You need IPs in a city you don't live in, and flying somewhere to plug in a cable is the plan
- Powered USB hubs are dropping devices as the fleet grows and you're chasing phantom disconnects
- One power cut takes down every proxy you sell at once
- You're spending more evenings maintaining the rig than the margin justifies
You don't have to pick one. A tethered rig at home plus dial-out phones in the cities you can't staff is cheaper than rebuilding either one, and it's how most fleets grow past one room.
If you're starting from scratch instead
Everything above assumes you already run a rig. If you don't, start with one phone and a data SIM before you buy hubs, shelving or anything else. One working phone teaches you more than any comparison table, including this one. The setup is in turn an old Android phone into a mobile proxy, and if you're weighing this as a business rather than a hobby, the margins are in how much mobile proxy operators make.
If your comparison is really against iProxy rather than the tethering model itself, that one splits differently and it's covered in iProxy alternatives.
Frequently asked questions
What is the closest alternative to XProxy?
Proxidize is the closest on shape, because it also sells you software and hardware to run a farm you own, with less cabling than a USB rack. iProxy and PocketProxy sit in a different category, since the phone dials out over its own cellular connection instead of being tethered, and that's what lets a handset live in a city you don't. So if you want the same kind of product from a different vendor, look at Proxidize first. If the thing bothering you is the cable itself, no tethered tool will fix it.
What is the main limitation of XProxy?
Geography, and it comes from the USB tethering rather than from the software. A tethered phone has to sit within cable reach of the machine running XProxy, so your entire fleet shares one physical address and one internet connection. That's fine while you're selling IPs from one region, and it becomes the binding constraint the first time a customer asks for a different city. Models where the phone dials out over its own cellular connection let a handset sit anywhere with signal, which is the one thing tethering can't do.
Is XProxy faster than a hosted relay?
Usually yes, and the gap is smaller than people expect. Tethering removes a network hop, so you save the round trip between the phone and whatever relay would otherwise sit in the middle. That shows up as tens of milliseconds. It matters for latency sensitive automation and it's close to invisible for account management or scraping, where the target site's own response time dwarfs it.
How many phones can one XProxy machine handle over USB?
The software is rarely the limit and the hardware usually is. Each handset needs a powered port that can hold a stable data connection while charging, so you're into powered hubs quickly, and cheap hubs are the most common cause of devices that vanish and reappear. Budget for good hubs and adequate cooling before you assume the ceiling is a software one, because a rig that works with six phones can behave very differently at twenty.
Do I need a static IP or port forwarding to run mobile proxies?
It depends entirely on the direction the connection travels. Anything you host yourself has to be reachable from outside, so you're into static addresses, port forwarding and firewall rules. Models where the phone dials out to a relay invert that, because the connection starts from inside your network and nothing needs to be exposed. If your internet provider uses carrier grade NAT and won't sell you a static address, that difference decides the question for you.
Can I run both a tethered rig and remote phones at once?
Yes, and it's a sensible way to grow. Keep the tethered rig for the location you physically control, where it's cheapest and fastest, and use a dial out model for the cities you can't staff. The usual mistake is committing to one architecture for the whole fleet because migration feels expensive, when running both costs less than flying to a second site to plug in cables.
Put one phone somewhere else
The cheapest way to find out whether you need a second location is to run a single handset in one, with no cable and no second rig.
