Managing multiple accounts in 2025 takes more than just opening a few tabs — you need tools built for privacy, control, and simplicity. X Browser, created by proxy provider Smartproxy, promises just that, offering a free solution for lightweight multi-accounting tasks. But is it enough for real-world needs, or is it just a basic browser with a proxy plug-in? Let’s break it down in this review. 

Key Takeaways: 

• X Browser is best suited for casual users who need quick proxy switching and basic account separation. 

• The 2025 version keeps things minimal — no mobile apps, no advanced fingerprinting. 

• It integrates directly with Smartproxy for easy proxy setup but lacks features for business-level use. 

• While it’s free to use with a Smartproxy plan, its functionality is limited compared to full-featured antidetect browsers. 

What Is X Browser and What’s New in 2025? 

X Browser is a free antidetect browser developed by Smartproxy, a well-known proxy provider based in Lithuania. It’s not trying to be everything at once — instead, it focuses on keeping things simple: one tool to manage proxies, create isolated sessions, and help users avoid basic tracking. If you already use Smartproxy’s residential or mobile proxies, X Browser is a lightweight bonus you get along with your plan. 

In 2025, not much has changed at first glance — but a few small things stand out: 

• Improved interface loading: the app opens and switches profiles faster. 

• Smoother login flow: if you’re signed into Smartproxy, X Browser logs you in automatically. 

• More stable MacOS app: the Mac version now runs more smoothly and doesn’t crash as often. 

It’s still a niche tool — not a full-featured antidetect browser. But for what it’s made for? It holds up surprisingly well. 

Installation, Setup, and User Experience 

Getting started with X Browser is fast — really fast. You download it from the Smartproxy dashboard, install it in a couple of clicks, and you’re good to go. If you’re already logged into your Smartproxy account, the browser syncs automatically — no extra login screens, no friction. 

Once you open the app, you’ll notice it’s clean and minimal. No tooltips, no onboarding walkthroughs, and honestly, not many buttons. That might sound like a downside, but for users who just want to launch a session and route it through a proxy, it actually keeps things straightforward. 

Each browser profile opens as a new tab group in the same window. It’s not true sandboxing, but for basic use cases — like checking multiple social media accounts or separating browser sessions — it gets the job done. No extensions to install, no proxy copy-pasting needed. Your proxies connect automatically through your Smartproxy subscription. 

However, if you’re expecting deep customization or tools to manage large-scale workflows, this isn’t that kind of browser. It’s designed for simplicity, not scale. 

Managing Profiles and Using Proxies 

Creating a profile in X Browser takes just a few clicks. There aren’t many options to tweak — mostly just basic settings like operating system, screen resolution, and your proxy connection. Everything else is kept minimal, which is either great or frustrating, depending on what you need. 

Here’s what stands out: 

• Quick Sessions: These are like disposable profiles. You launch one, use it, and it’s gone when you close the tab. Ideal for one-off tasks or testing a new proxy. 

• Proxy Setup: This is where X Browser shines for Smartproxy users. Your proxy list is pulled directly from your Smartproxy account, so you don’t need to manually paste IPs or ports. Just pick a location, and the profile is ready to go. 

• Tab-Based Isolation: Profiles aren’t isolated in separate browser windows like in more advanced antidetect tools. Instead, they run as grouped tabs within one instance. It works for basic separation, but it’s not foolproof against more aggressive fingerprint detection systems. 

There’s no fingerprint customization beyond OS and screen size, and you can’t manage cookies, WebRTC, or other browser fingerprints in detail. So while the proxy integration is smooth, the browser’s capabilities stay pretty surface-level. 

If you’re handling a few accounts and want something lightweight that works out of the box with Smartproxy, this setup is convenient. But if you’re juggling dozens of accounts, running ads, or scraping data — X Browser won’t give you the control or flexibility you’ll need. 

Privacy Features and Fingerprinting 

X Browser keeps things basic when it comes to privacy. You get IP masking through Smartproxy and some light profile isolation, but that’s about it. 

There’s no control over advanced fingerprints like Canvas, WebGL, or timezone. You can only tweak OS and screen resolution—nothing more. Tools like Pixelscan will easily detect that you’re not using a standard browser, so it’s not built for platforms with strong detection systems. 

Also, there’s no mobile fingerprinting, and you can’t use extensions or automation scripts. It’s fine for light tasks, but not reliable for anything like ad accounts, scraping, or automation at scale. 

So, good enough for casual browsing — just not built for stealth. Let’s look at support and whether the app’s being kept up to date. 

Support, Updates, and Limitations 

One thing Smartproxy does well is customer support. If you run into issues with X Browser — whether it’s connection problems or something not loading — you can reach their team via chat or email. They usually respond fast, and they know their product well. 

However, X Browser itself doesn’t seem to be a top priority. Updates are rare, and there’s no public changelog or clear roadmap. The browser works, but it hasn’t evolved much beyond its core use: simple proxy browsing. 

Here’s where limitations start to stack up: 

• No team features or shared profile access 

• No mobile apps or cross-device sync 

• No automation support 

• No cloud storage or backup for profiles 

In short, it’s a lightweight desktop tool with just enough functionality for basic multi-account browsing. If you’re running a serious operation or managing accounts at scale, you’ll feel these gaps quickly.
