Smartproxy Browser vs Send.win — Which One Actually Fits?
Comparing Smartproxy Browser vs Send.win comes down to what you need most: premium residential proxies baked into a scraping-first browser, or a broader antidetect platform with automation APIs, cloud sessions, and team management at a lower price. Smartproxy’s X Browser excels at proxy-powered data collection with its massive residential IP pool. Send.win covers more ground — multi-account management, headless automation via Selenium/Puppeteer/Playwright, and cloud browser sessions that need no local install. Below, we break down every difference that matters so you stop paying for features you don’t use.
What Is Smartproxy Browser (X Browser)?
Smartproxy Browser, officially called X Browser, is the antidetect browser built by the Smartproxy team — the same company behind one of the largest residential proxy networks on the market. It launched as a natural extension of Smartproxy’s proxy infrastructure: instead of routing traffic through proxies in your existing browser, you get a purpose-built Chromium shell where fingerprint masking and proxy rotation are integrated from the start.
That integration is X Browser’s defining strength. When you create a profile, it automatically pulls from Smartproxy’s residential, datacenter, or ISP proxy pools. There’s no manual proxy import step, no paste-a-list workflow. You pick a location, and the browser handles the rest. For web scraping teams and data-collection operations, this tight coupling between proxy and browser is genuinely useful — it removes an entire layer of configuration that typically eats hours.
Fingerprint-wise, X Browser covers the basics: canvas, WebGL, audio context, timezone, language, and screen resolution spoofing. It’s competent, though not as deeply configurable as some standalone antidetect tools. The product is clearly optimized for Smartproxy’s existing customer base — people who already pay for residential bandwidth and want a browser that makes that bandwidth easier to use.
What Is Send.win?
Send.win approaches the antidetect space from a different angle. Rather than building around a proxy network, it’s built around profile management, automation, and team collaboration.
The product has two modes: Sendwin Browser, a native desktop app for Windows, macOS, and Linux, and cloud browser sessions that run profiles remotely with no local installation. Both modes share the same profile library, so you can start a session on your desktop and continue it from the cloud — or hand a cloud-only link to a team member who doesn’t need the full client.
Where Send.win diverges sharply from X Browser is its session isolation architecture and automation layer. The Automation API supports Selenium, Puppeteer, and Playwright, letting you script profile launches, page interactions, and data extraction programmatically. This isn’t a scraping-only feature — it’s used for automated account warm-up, ad verification, social media scheduling, and QA testing across isolated profiles.
Send.win also includes proxy bandwidth — 5 GB on Pro, 20 GB on Team — so you can start using proxies out of the box. Beyond that, it’s fully proxy-agnostic: you can plug in any external provider (residential, datacenter, mobile, ISP) or skip proxies entirely for local testing. That flexibility matters if you already have proxy contracts, need a specialized proxy type, or are managing accounts that don’t need IP rotation.
Feature-by-Feature Comparison
Let’s put the two side by side on the dimensions that actually affect daily workflows.
| Feature | Smartproxy X Browser | Send.win |
|---|---|---|
| Primary Use Case | Web scraping and data collection | Multi-account management, automation, team ops |
| Desktop App | Windows, macOS | Windows, macOS, Linux (Sendwin Browser) |
| Cloud Sessions | No | Yes — run profiles without installing anything |
| Built-in Proxies | Yes — Smartproxy residential, datacenter, ISP | Yes — 5-20GB included; also supports external proxies |
| Proxy Flexibility | Smartproxy-only (built-in integration) | Any HTTP/SOCKS5 proxy from any provider |
| Automation API | Limited (no public Selenium/Puppeteer/Playwright API) | Full API — Selenium, Puppeteer, Playwright (Pro+) |
| Profile Limit | Varies by Smartproxy plan | 150 (Pro) / 500 (Team) |
| Team Seats | Not a primary feature | Up to 16 seats (Team plan) |
| Fingerprint Masking | Canvas, WebGL, audio, timezone, screen | Canvas, WebGL, audio, timezone, fonts, hardware, WebRTC, geolocation |

| Linux Support | No | Yes |
| Free Trial | Included with Smartproxy subscription | 30 days, no credit card |
Proxy Quality and Integration
This is where Smartproxy genuinely wins — and we should be direct about it.
Smartproxy operates one of the largest residential proxy pools available, with over 55 million IPs across 195+ locations. When you use X Browser, those proxies are one click away. No setup, no credentials, no paste-and-test loops. For teams doing large-scale scraping, ad verification, or price monitoring where IP quality and rotation speed are the bottleneck, this integration is a real productivity multiplier.
The residential IPs themselves are high quality. They’re sourced ethically (peer-to-peer network with opt-in users), rotate automatically, and have strong geo-targeting granularity down to the city level. If your primary workflow is “hit target sites with thousands of requests through clean residential IPs,” Smartproxy’s X Browser makes that frictionless.
Send.win takes a hybrid approach: proxy bandwidth is included — 5 GB on Pro and 20 GB on Team — so you can start using proxies immediately without a separate subscription. On top of that, Send.win is fully proxy-agnostic: you can also paste in credentials from any external provider — Smartproxy itself, Bright Data, Oxylabs, IPRoyal, or a private pool. If you find a better deal on mobile proxies for Instagram or need datacenter speed for a specific scraper, you switch without changing browsers. The included bandwidth covers most users out of the box, and BYOP adds flexibility when you need it.
For users who already have proxy subscriptions, Send.win avoids double-paying. For users who don’t yet have proxies and want the simplest possible onramp, Smartproxy’s integration is hard to beat. Check our proxy browsers guide for a deeper look at how proxy integration affects browser isolation.
Fingerprint Quality
Both tools mask browser fingerprints, but the depth of coverage differs.
Smartproxy’s X Browser handles the core vectors: canvas rendering, WebGL renderer strings, audio context hashing, timezone, language headers, and screen resolution. For most scraping use cases, this is sufficient — target sites are checking whether you look like a real browser from the claimed location, and X Browser passes those checks reliably when paired with clean residential IPs.
Send.win covers the same core vectors plus additional surfaces: font enumeration, hardware concurrency, device memory, WebRTC leak protection, and GPS-level geolocation spoofing. Each profile gets a consistent, persistent fingerprint that survives restarts — important for multi-account management where you need the same “device” to log in repeatedly over weeks without triggering platform suspicion.
The practical difference? For scraping, both are adequate. For managing long-lived accounts on platforms like Facebook, Amazon, or TikTok that run sophisticated device-fingerprinting checks over time, the deeper fingerprint coverage in Send.win reduces detection risk. The fingerprint has to be not just different, but consistent and realistic across sessions. For a deeper dive into how modern sites detect automation and how fingerprinting fits the picture, see our complete guide to bypassing anti-bot detection.
Automation Capabilities
Automation is Send.win’s strongest differentiator, and it’s where X Browser falls noticeably short.
Send.win’s Automation API lets you programmatically launch profiles, navigate pages, fill forms, click elements, and extract data using the same Selenium, Puppeteer, or Playwright code you’d write for any Chromium browser. The API is available starting on the Pro plan ($9.99/month). You can build account warm-up sequences, automate social media posting across dozens of profiles, run ad verification scripts, or orchestrate QA testing — all through standard browser automation frameworks with no proprietary SDK to learn.
Smartproxy’s X Browser doesn’t offer a comparable automation API. It’s designed as a manual browser — you open profiles, browse, and close them. For scraping automation, Smartproxy pushes users toward their separate API products (Web Scraping API, SERP API) rather than automating through X Browser itself. If you need both antidetect profiles and programmable automation in the same tool, this is a significant gap.
Team Features and Collaboration
If you’re a solo operator, this section matters less. If you run an agency, e-commerce operation, or media buying team, it matters a lot.
Send.win’s Team plan ($29.99/month, $20.99/month billed annually) includes up to 16 seats, 500 profiles, cloud-synced profile sharing, and role-based access. A manager can create profiles, assign them to team members, and monitor usage — all without sharing credentials or proxy configs. Cloud browser sessions mean remote team members don’t even need the desktop app installed.
Smartproxy’s X Browser is primarily a single-user tool. While Smartproxy’s broader platform supports sub-users for proxy management, the antidetect browser itself wasn’t built around team workflows the way Send.win was. There’s no equivalent to Send.win’s managing multiple accounts across a team with shared profiles and granular permissions.
Pricing Comparison
Pricing is where the comparison gets complicated because the two products bundle different things.
| Plan Detail | Smartproxy X Browser | Send.win Pro | Send.win Team |
|---|---|---|---|
| Monthly Price | Included with Smartproxy plans (from ~$7.50/mo for micro plans) | $9.99/mo ($6.99/mo annual) | $29.99/mo ($20.99/mo annual) |
| Profiles | Varies by plan | 150 | 500 |
| Proxy Bandwidth | Included (plan-dependent GB) | 5 GB included | 20 GB included |
| Automation API | Not available | Included | Included |
| Team Seats | — | 1 | 16 |
| Cloud Sessions | — | Included | Included |
| Free Trial | 3-day free trial | 30-day, no credit card | 30-day, no credit card |
Here’s the key nuance: both products now include proxy bandwidth. Smartproxy bundles residential IPs with its subscription, and Send.win includes 5 GB (Pro) or 20 GB (Team) of proxy bandwidth in every plan. The difference is that Send.win also lets you plug in external proxies from any provider, giving you a fallback if you outgrow the included allocation or need a specific proxy type the built-in pool doesn’t cover.
If you’re already paying for Smartproxy proxies, X Browser is essentially free — it’s a convenience layer on top of your existing subscription. If you want an all-in-one package with included bandwidth, automation, cloud sessions, and team management, Send.win at $6.99/month (annual Pro) is hard to beat on value per feature — especially since you can start using proxies immediately without a separate purchase.
Which Should You Pick?
The honest answer is that these tools serve overlapping but different audiences.
Choose Smartproxy X Browser if:
- You’re already a Smartproxy customer using their residential or datacenter proxies
- Your primary workflow is web scraping, price monitoring, or SERP tracking
- You need high-volume residential IP rotation with minimal configuration
- You work solo and don’t need team features or automation APIs
- Proxy quality and IP pool size are your top priorities
How Send.win Helps With Smartproxy Browser Vs Send Win
Send.win is an antidetect browser built for exactly this kind of work — every profile is a clean, isolated identity:
- Isolated profiles – unique fingerprint, separate cookies and storage per profile
- Stealth engine – canvas, WebGL, fonts, and audio spoofed at the engine level
- Desktop app + cloud sessions – native app for Windows, macOS, and Linux, or run profiles in the cloud with no install
- Built-in residential proxies – with automatic timezone, locale, and WebRTC matching
- Team features – share logged-in profiles with teammates without sharing passwords
Try the instant cloud browser demo — no install, no signup — or download the desktop app. The 30-day free trial needs no credit card, and paid plans start at $6.99/month billed annually (see pricing).
Choose Send.win if:
- You manage multiple accounts on social media, e-commerce, or advertising platforms
- You need headless automation with Selenium, Puppeteer, or Playwright
- You run a team and need shared profiles, role-based access, and cloud sessions
- You want proxy flexibility — use any provider, switch anytime
- You need Linux support or cloud browser sessions without a local install
- Budget matters and $6.99/month for 150 profiles with automation fits better than proxy-bundled pricing
Use both if:
You can actually use Smartproxy’s residential proxies inside Send.win profiles. Buy bandwidth from Smartproxy for IP quality, run profiles through Send.win for automation and team management. This isn’t as unusual as it sounds — separating your proxy provider from your browser tool gives you the flexibility to optimize each layer independently.
Common Pitfalls When Choosing
Overpaying for Bundled Proxies You Don’t Use
If you pick Smartproxy for the browser but only use 10% of the included proxy bandwidth, you’re subsidizing unused data transfer. Conversely, if you pick Send.win but then buy expensive residential proxies you don’t actually need (maybe datacenter IPs would suffice), you’ve created unnecessary cost on the other side. Match the proxy type to the actual detection threat level of your target sites.
Ignoring Automation Needs Until It’s Too Late
Starting with manual browser profiles is fine for 5-10 accounts. At 50+, manual management breaks down. If you can see scale coming, choosing a tool with automation from day one (Send.win’s Automation API) saves a painful migration later. Retrofitting automation into a workflow built around manual browsing is always more expensive than starting with it.
Assuming Fingerprint Masking Alone Is Enough
Neither tool’s fingerprint spoofing guarantees undetectable accounts if your behavioral patterns are suspicious. Logging into 20 accounts from the same IP in 10 minutes, or using identical posting patterns across accounts, will trigger platform detection regardless of how clean your fingerprint looks. The browser is one layer in a multi-layer strategy.
🏆 Send.win Verdict
Smartproxy X Browser is a solid choice if residential proxy quality is your primary concern and you’re already in the Smartproxy ecosystem. But for most multi-account operators, Send.win delivers more functionality per dollar: 150 profiles at $6.99/month (annual), a full Automation API for Selenium/Puppeteer/Playwright, cloud browser sessions, team collaboration with up to 16 seats, and the freedom to use any proxy provider. If your workflow goes beyond data collection into account management, ad operations, or team-based scaling, Send.win covers ground that X Browser simply wasn’t designed for.

Frequently Asked Questions
Can I use Smartproxy proxies inside Send.win?
Yes. Send.win supports any HTTP or SOCKS5 proxy. You can paste your Smartproxy residential proxy credentials into a Send.win profile and get the best of both: Smartproxy’s IP quality with Send.win’s automation and team features.
Is Smartproxy X Browser free?
X Browser is included at no extra cost with an active Smartproxy subscription. However, you’re paying for proxy bandwidth — the browser itself is the free layer on top of that paid service. There’s a 3-day free trial for new Smartproxy users.
Does Send.win include proxies?
Yes. Every Send.win plan includes proxy bandwidth — 5 GB on Pro and 20 GB on Team. You can use the included proxies right away without a separate subscription. Send.win also supports external proxies from any provider (HTTP or SOCKS5), so you can supplement the included bandwidth or switch to a specialized proxy type whenever you need to.
Which tool is better for web scraping?
For manual or low-volume scraping through a browser interface with built-in residential IPs, Smartproxy X Browser is more convenient. For automated, high-volume scraping using Puppeteer, Playwright, or Selenium scripts, Send.win’s Automation API is more capable — and includes proxy bandwidth out of the box (5-20 GB depending on plan), with the option to add external proxies for heavier workloads.
Can I run Send.win without installing anything?
Yes. Send.win’s cloud browser sessions let you run profiles in the cloud with no local installation required. The Sendwin Browser desktop app is available for Windows, macOS, and Linux if you prefer local execution, but cloud sessions work from any device with a web browser.
How many profiles can I create in each tool?
Send.win Pro supports 150 profiles, and Team supports 500 profiles (with add-on profiles available at $0.05 each). Smartproxy X Browser’s profile limits depend on your Smartproxy plan tier and may not be as clearly defined since the browser is a secondary product within the Smartproxy platform.
Does Smartproxy X Browser support Selenium or Playwright automation?
No. X Browser is designed for manual browsing with antidetect profiles. For programmatic scraping, Smartproxy offers separate API products (Web Scraping API, SERP API) that don’t go through the browser. Send.win’s Automation API, available on both Pro and Team plans, supports Selenium, Puppeteer, and Playwright directly against browser profiles.
Which is better for managing social media accounts?
Send.win. Social media account management requires persistent fingerprints across sessions, team-based profile sharing, and often automation for scheduling or warm-up. Send.win’s profile persistence, cloud sync, team seats, and Automation API are purpose-built for this. X Browser’s scraping-first design doesn’t prioritize long-lived account management the same way.
