Smartproxy Antidetect Browser Review: Is X Browser Worth Using in 2026?
Smartproxy has been a trusted name in the proxy industry for years, offering residential, datacenter, and mobile proxies to thousands of businesses. In a strategic move to capture more of the multi-account management market, Smartproxy launched its own antidetect browser — X Browser. But can a proxy company build a competitive antidetect tool?
In this detailed Smartproxy antidetect browser review, we examine X Browser from every angle: its seamless proxy integration (the main selling point), fingerprint masking capabilities, pricing structure, real-world performance, and how it compares to dedicated antidetect browsers that have been refining their craft for years. Whether you’re already a Smartproxy customer or evaluating it fresh, this review will help you decide if X Browser belongs in your workflow.
What Is Smartproxy’s X Browser?
X Browser is Smartproxy’s antidetect browser solution, designed specifically to work with Smartproxy’s extensive proxy network. Unlike standalone antidetect browsers that treat proxy integration as one of many features, X Browser was built from the ground up with proxy connectivity as its core architecture.
The browser is Chromium-based and provides browser fingerprint management, multiple browser profiles, and team collaboration features. It’s available as a free add-on for Smartproxy proxy plan subscribers and as a limited standalone product.
Key Features
- Native Smartproxy integration — one-click connection to residential, datacenter, and mobile proxies
- Browser fingerprint management — Canvas, WebGL, timezone, language, and user agent spoofing
- Residential IP pool access — 65M+ IP addresses across 195+ locations
- Profile management — create and manage multiple isolated browser identities
- Team sharing — share profiles with team members
- Cookie management — import/export cookies in standard formats
- Session management — sticky and rotating session options tied to proxy configuration
- Chrome extension support — install extensions in individual profiles
Smartproxy X Browser Pricing Structure
X Browser’s pricing model is unique because it’s fundamentally tied to Smartproxy’s proxy plans rather than standing alone.
Bundled with Proxy Plans
| Smartproxy Plan | Price | X Browser Access | Profiles Included | Proxy Traffic |
|---|---|---|---|---|
| Micro | $30/month | Included free | Up to 50 | 2 GB residential |
| Starter | $75/month | Included free | Up to 200 | 8 GB residential |
| Regular | $200/month | Included free | Up to 500 | 25 GB residential |
| Advanced | $400/month | Included free | Unlimited | 50 GB residential |
Standalone X Browser
Users can access X Browser without a Smartproxy proxy subscription, but functionality is limited. The free standalone version provides basic profile management with up to 10 profiles but requires you to bring your own proxies. Without Smartproxy’s native integration, you lose the primary value proposition of X Browser — at which point you’re essentially using a basic antidetect browser that competes unfavorably with dedicated alternatives.
Pricing Analysis
The bundled pricing model is both X Browser’s greatest strength and its most significant limitation. If you’re already paying for Smartproxy proxies, getting an antidetect browser for free is excellent value. You’re essentially getting two tools for the price of one.
However, if you’re comparing total costs — antidetect browser plus proxies — the equation changes. A user on Smartproxy’s Starter plan pays $75/month for both proxies and X Browser, but they’re limited to 8 GB of residential traffic. If your proxy needs are modest, this is competitive. If you need more traffic or want to use proxies from multiple providers, the bundled model becomes restrictive.
Understanding the difference between proxy types is crucial when evaluating this bundled offer. Our guide on residential vs datacenter proxies explains which type suits different use cases and why proxy choice matters for antidetect operations.
Proxy Integration: The Star Feature
If there’s one area where X Browser genuinely excels, it’s proxy integration. This is where Smartproxy’s core expertise shines through.
One-Click Proxy Assignment
Creating a new browser profile with a properly configured proxy takes seconds in X Browser. Select your target country or city, choose between residential, datacenter, or mobile IP, set your session type (sticky or rotating), and the proxy is configured automatically. There’s no manual proxy entry, no copying IP:port:user:pass strings, and no connectivity testing — it just works.
Residential IP Pool Quality
Smartproxy maintains one of the largest residential proxy pools in the industry — over 65 million IPs across 195+ locations. For antidetect browsing, residential IPs are essential because datacenter IPs are easily detected and flagged by most platforms. Having this pool integrated directly into the browser eliminates a significant setup step.
The IP quality is generally high, with good trust scores on most platforms. Smartproxy filters out flagged IPs and maintains pool freshness, which reduces the risk of inheriting a previously abused IP address.
Automatic Geo-Matching
X Browser automatically adjusts fingerprint parameters to match the proxy location. When you select a residential IP in Berlin, Germany, the browser automatically sets the timezone to CET, the language to German, and adjusts other locale-dependent parameters. This automatic consistency is valuable — manual mismatches between proxy location and fingerprint settings are a common detection trigger that X Browser eliminates.
Session Persistence
For account management tasks that require consistent identity over time, X Browser’s sticky session feature maintains the same IP address for your profile across browsing sessions (within Smartproxy’s session duration limits, typically up to 30 minutes for residential IPs). This is superior to random IP rotation for maintaining account consistency.
For more advanced proxy configuration strategies, our rotating proxy setup guide covers best practices that apply across different antidetect browsers.
Fingerprint Management Assessment
While proxy integration is X Browser’s strength, fingerprint management is where it shows its limitations as a newer entrant to the antidetect market.

What X Browser Doesn’t Handle Well
- AudioContext fingerprinting: Limited or no spoofing
- Hardware concurrency: Not customizable in all configurations
- GPU rendering consistency: WebGL combinations occasionally don’t match real hardware
- Navigator platform details: Some properties aren’t fully spoofed
- Client Hints API: Incomplete coverage of newer Chromium identification methods
Fingerprint Test Results
| Detection Platform | X Browser Result | Notes |
|---|---|---|
| BrowserLeaks.com | Pass | Core parameters spoofed correctly |
| Pixelscan.net | Partial Pass | Minor inconsistencies flagged |
| Creepjs | Fail | Multiple fingerprint components flagged |
| FingerprintJS Pro | Fail | Spoofing detected |
| IP Quality Score | Pass | High IP trust scores (residential IPs) |
X Browser’s fingerprint quality is basic to moderate. It handles the fundamental parameters adequately but lacks the depth and consistency of dedicated antidetect browsers like Multilogin or GoLogin. The advantage of excellent residential IPs partially compensates — many detection systems weigh IP reputation heavily, so a clean residential IP can mask moderate fingerprint weaknesses.
X Browser vs Dedicated Antidetect Browsers
This comparison is essential for any Smartproxy antidetect browser review because it highlights the fundamental difference between a proxy-first tool with antidetect features and an antidetect-first tool with proxy support.
| Feature | X Browser | Multilogin | GoLogin | Send.win |
|---|---|---|---|---|
| Primary Focus | Proxy integration | Fingerprint spoofing | Balance of both | Cloud antidetect |
| Fingerprint Quality | ⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ |
| Proxy Integration | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ |
| Browser Engines | Chromium only | Chromium + Firefox | Chromium (Orbita) | Cloud Chromium |
| Cloud Access | No | Sync only | Web version | Full cloud |
| Built-in Proxies | Yes (Smartproxy) | No | Free proxies (limited) | No |
| Price (browser only) | Free (with proxy plan) | From $99/mo | From $49/mo | Competitive |
| Automation API | Basic | Comprehensive | Good | Available |
| Team Features | Basic sharing | Advanced permissions | Good sharing | Excellent |
The verdict is clear: X Browser excels at proxy integration but lags behind dedicated antidetect browsers in fingerprint quality, automation capabilities, and advanced features. It’s a proxy tool with browser features, not a browser tool with proxy features — and that distinction matters. For comprehensive rankings, check our guide to the best antidetect browsers in 2026.
Ideal Use Cases for X Browser
Web Scraping and Data Collection
This is X Browser’s strongest use case. The combination of high-quality residential IPs with browser-level fingerprint masking is ideal for scraping websites that block datacenter IPs and detect headless browsers. The automatic geo-matching ensures your scraping requests appear to originate from real users in target locations.
For large-scale data collection operations, the seamless proxy rotation combined with browser profiles reduces the complexity of maintaining scraping infrastructure. Our guide on web scraping without getting blocked covers additional techniques that complement X Browser’s proxy capabilities.
Market Research Across Regions
Viewing search results, pricing, and content as they appear in different countries is straightforward with X Browser. The extensive geographic coverage of Smartproxy’s IP pool means you can create profiles for virtually any location, with the browser automatically adjusting locale settings for consistency.
Social Media Account Warming
For the initial phase of creating and warming new social media accounts, X Browser’s combination of clean residential IPs and basic fingerprint masking is adequate. The low detection risk of residential IPs helps new accounts avoid immediate flagging during the critical early days.
Ad Verification
Checking how ads appear in different geolocations is another natural fit. Advertisers and agencies can use X Browser profiles to verify ad placement, creative rendering, and landing page functionality across target markets without triggering ad fraud detection systems.
Where X Browser Falls Short
X Browser is not well-suited for:
- High-stakes account management on platforms with advanced detection (Google Ads, Amazon, PayPal)
- Long-term multi-account operations where fingerprint consistency over months is critical
- Operations requiring Firefox-based fingerprints for browser diversity
- Complex automation workflows requiring Playwright or advanced API operations
- Users who want proxy provider flexibility — X Browser’s value is tied to using Smartproxy’s proxies
Limitations and Concerns
Vendor Lock-In
X Browser’s biggest limitation is vendor lock-in. Its primary value comes from Smartproxy proxy integration — without it, you have a basic antidetect browser that underperforms compared to dedicated alternatives at similar or lower price points. If you decide to switch proxy providers in the future (due to pricing, IP quality, or geographic coverage), X Browser loses its competitive advantage.
Limited Fingerprint Depth
As detailed in the fingerprint assessment, X Browser’s spoofing doesn’t reach the depth or consistency of dedicated antidetect browsers. For casual use, this is acceptable. For professional-grade operations where account security is paramount, the fingerprint limitations represent real risk.
No Firefox Engine
Running Chromium-only means all your profiles share the same browser engine base. Dedicated antidetect browsers that offer Firefox-based engines (like Multilogin’s Stealthfox or AdsPower’s Firefox kernel) provide greater fingerprint diversity, making it harder for platforms to correlate profiles based on underlying engine signatures.
Desktop-Only Architecture
Like most antidetect browsers, X Browser requires local installation. There’s no cloud-based access, which means you’re tied to the specific device where the software is installed. For distributed teams or users who work from multiple locations, this creates workflow limitations.
Proxy Cost Scaling
While the browser itself is free with a proxy plan, residential proxy traffic is metered. Heavy users can quickly exhaust their bandwidth allocation, especially when running multiple profiles actively. The cost-per-GB for residential proxies adds up — a user running 20 active profiles for 8 hours daily might consume 5-10 GB of bandwidth per month, pushing them toward higher-tier plans.
Performance and Stability
X Browser runs smoothly on modern hardware with performance characteristics similar to other Chromium-based antidetect tools.
| Metric | X Browser Result |
|---|---|
| Application startup | 3.5 seconds |
| Profile launch time | 3.0 seconds |
| RAM per idle profile | ~170 MB |
| RAM per active profile | ~320 MB |
| Proxy connection speed | Excellent (native integration) |
| Max concurrent profiles (16GB RAM) | ~15-20 |
Proxy connectivity is noticeably faster than manually configured proxies in other antidetect browsers. The native integration eliminates authentication delays and connection setup overhead, resulting in snappier page loads and more responsive browsing.
Who Should Use Smartproxy’s X Browser?
X Browser is best suited for users who:
- Already subscribe to Smartproxy and want a free antidetect add-on
- Primarily need antidetect capabilities for web scraping and data collection
- Value seamless proxy integration over advanced fingerprint features
- Operate on platforms with moderate detection systems
- Need geographic flexibility across 195+ locations

Frequently Asked Questions
Is Smartproxy’s X Browser free?
X Browser is free when bundled with any Smartproxy proxy subscription plan (starting from $30/month for the Micro plan). There’s also a limited standalone free version with up to 10 profiles, but without Smartproxy proxy integration, the browser loses its primary value proposition. You’ll need to bring your own proxies, and the browser’s fingerprint capabilities alone don’t justify choosing it over dedicated antidetect alternatives.
How does X Browser compare to Multilogin?
X Browser and Multilogin serve different primary purposes. Multilogin is a dedicated antidetect browser with industry-leading fingerprint quality, dual browser engines, and comprehensive automation APIs. X Browser is primarily a proxy integration tool with antidetect features added. Multilogin wins decisively on fingerprint quality, browser diversity, and automation. X Browser wins on proxy integration convenience and bundled pricing for existing Smartproxy customers.
Can I use X Browser with proxies from other providers?
Yes, X Browser supports manual proxy configuration with HTTP, HTTPS, SOCKS4, and SOCKS5 protocols from any provider. However, you lose the one-click proxy assignment, automatic geo-matching, and IP pool access that make X Browser distinctive. Using third-party proxies in X Browser gives you a basic antidetect browser without its key differentiator — at which point dedicated alternatives offer better value.
Is X Browser good for managing social media accounts?
X Browser can handle basic social media account management on platforms like Facebook, Instagram, and TikTok. The clean residential IPs from Smartproxy’s pool provide good IP trust scores, and the basic fingerprint masking is sufficient for platforms that don’t employ advanced device fingerprinting. For long-term multi-account management at scale, a dedicated antidetect browser with stronger fingerprint quality provides better protection.
What are the main limitations of X Browser?
The main limitations include: moderate fingerprint quality that fails against advanced detection systems, vendor lock-in to Smartproxy’s proxy network for best functionality, Chromium-only engine (no Firefox option for fingerprint diversity), desktop-only architecture with no cloud access, basic automation API compared to dedicated tools, and metered bandwidth that can become expensive for heavy usage.
How many browser profiles can I create in X Browser?
The number of profiles depends on your Smartproxy plan: Micro plan allows 50 profiles, Starter allows 200, Regular allows 500, and Advanced provides unlimited profiles. The standalone free version limits you to 10 profiles. Note that the number of profiles you can run simultaneously is still limited by your local hardware resources, regardless of plan limits.
Is X Browser suitable for web scraping?
Yes, web scraping is X Browser’s strongest use case. The combination of high-quality residential IPs, automatic geo-matching, and browser-level fingerprint masking makes it effective for scraping websites that block datacenter IPs and detect automation tools. The native proxy rotation features simplify large-scale data collection workflows. For pure scraping operations, X Browser’s proxy advantages often outweigh its fingerprint limitations.
Should I choose X Browser or a dedicated antidetect browser?
Choose X Browser if you’re already a Smartproxy customer and primarily need antidetect capabilities for web scraping, market research, or moderate-security platforms. Choose a dedicated antidetect browser if fingerprint quality is critical, you need cloud-based access, you want proxy provider flexibility, or you’re managing accounts on platforms with advanced detection systems. For the best of both worlds — strong fingerprints and convenient cloud access — consider a cloud-native solution like Send.win.
