A cloud browser runs an entire browsing session on remote servers and streams only the pixels to your screen, so cookies, scripts, downloads, and extensions never touch your device. Send.win delivers this as on-demand cloud browser sessions billed by cloud browsing time, alongside a native Sendwin Browser desktop app for teams who want a local-first option with encrypted cloud sync. This guide explains how both modes work, when to use each, and how to get started safely today.
What Is a Cloud Browser, and Why Does It Matter?
A cloud browser is a full, real browser instance that executes on provider infrastructure instead of your laptop or phone. You interact with it through a video-like stream: clicks, scrolls, and keystrokes go up, pixels come back down. Because the page’s actual code never runs on your endpoint, a malicious script, a drive-by download, or a tracking pixel on a sketchy site has nothing local to attach to. Security teams call this pattern remote browser isolation, and it has quietly become one of the simplest ways to browse risky or unfamiliar sites without gambling with your main machine.
The practical benefits stack up quickly:
- No local footprint. Sessions don’t leave cookies, cached files, or browsing history on your device.
- Lower blast radius. If a page is compromised, the damage is contained to a disposable cloud session, not your hard drive.
- Instant collaboration. You can hand a teammate a live, logged-in session without ever typing a password into a shared doc.
- Zero setup. There’s nothing to configure locally — open a session and you’re browsing within seconds.
Cloud Browser vs. Extensions, Local Profiles, and VMs
Most people first try to solve the “I need several isolated identities” problem with what’s already on their machine: extra Chrome profiles, incognito windows, or a second browser entirely. Profiles are convenient, but they still execute locally and can leak signals across accounts if you’re not careful. Incognito mode isn’t real isolation — it just skips history and some cookies. A second browser adds clutter without adding much protection. And a full remote desktop or VM technically works, but it’s heavyweight: you’re maintaining an entire operating system just to get an isolated tab.
A dedicated cloud browser versus extensions comparison usually comes down to this: extensions and local profiles are fast to set up but share your machine’s context, while a cloud browser gives you true tab-level and session-level separation without any of that shared state. For agencies and teams that need clean, multi-login profiles for teams, that separation is the whole point — one compromised or flagged account should never put the others at risk.
Two Ways to Browse with Send.win
Send.win doesn’t force you into one architecture. It offers two distinct modes depending on how much local control you want and how your team is set up.
The Sendwin Browser (native desktop app)
Sendwin Browser is a downloadable, native application for Windows, macOS, and Linux. It’s local-first — your profiles, sessions, and browsing data live on your machine — but everything syncs to the cloud in encrypted form, so you can pick up the same sessions on another installed device. Because it’s a real installed application rather than a hosted stream, it’s the mode automation tooling plugs into: Send.win’s Automation API lets you drive local sessions with standard tools like Selenium, Puppeteer, or Playwright, exactly the way you’d automate any desktop Chromium browser.
Cloud browser sessions
Cloud sessions are the opposite end of the spectrum: nothing installs locally at all. The browser runs entirely on Send.win’s servers and streams to whatever device you’re on — a work laptop, a shared kiosk, a tablet while traveling. This mode is metered by cloud browsing time rather than a flat monthly allotment, which makes it a good fit for occasional, high-risk, or on-the-go browsing where you don’t want to install anything, even temporarily.
Most teams end up using both: the desktop app for daily-driver multi-account work and automation, and cloud sessions for one-off tasks, unfamiliar links, or browsing from a device they don’t fully control.
Local Browser vs. Sendwin Browser vs. Send.win Cloud Sessions
| Capability | Regular local browser | Sendwin Browser (desktop app) | Send.win cloud sessions |
|---|---|---|---|
| Installation | Already installed | Native app, one-time install | None — runs entirely in the cloud |
| Where code executes | Your device | Your device (local-first) | Remote servers, streamed to you |
| Cross-account isolation | Weak (shared profile/context) | Strong (per-session containers) | Strong (per-session containers) |
| Password-free sharing | Not supported | Yes, via session sharing | Yes, via session sharing |
| Automation support | Manual scripting only | Selenium / Puppeteer / Playwright via Automation API | Not applicable |
| Best for | Everyday single-account browsing | Daily multi-account work, automation, teams | Occasional, high-risk, or install-free browsing |
How Send.win Keeps You Safer by Default
Whether you’re on the desktop app or a cloud session, Send.win’s core security model is the same: every login gets its own isolated container, so cookies, local storage, and cache never bleed across accounts. That containment is what makes browser isolation genuinely useful for day-to-day work rather than just a security-team talking point — it protects you from accidental cross-posting under the wrong account just as much as it protects you from a malicious script.
On top of isolation, sessions can be shared with a teammate or client without ever exposing the underlying password, time-boxed so access automatically expires, and selectively blurred or blocked on pages you don’t want a guest to see — think billing dashboards, payout details, or admin settings. None of that requires the guest to have an account of their own; they simply open the link you send them.
Feature Deep Dive
- Multiple logins made easy. Run dozens of accounts on the same platform in parallel without the sign-in/sign-out shuffle.
- Session isolation on every tab. No shared cookies or storage between sessions, so cross-account mix-ups simply can’t happen.
- Bring-your-own proxy. Attach a proxy to an individual session for accurate geo-testing, ad review, or localized SEO checks — more precise than a blanket VPN.
- Share account, not password. Invite a collaborator into a live, logged-in session and revoke access whenever you want.
- Blur and block sensitive pages. Hide billing, payout, or admin views before you hand a session to someone else.
- Session timers. Set access windows — 30 minutes, an hour, a day — so guest access expires on its own.
- Automation API. Starting on the Pro plan, drive Sendwin Browser sessions programmatically with Selenium, Puppeteer, or Playwright for QA, scraping, or repetitive workflows.
- Cross-device continuity. Sendwin Browser’s encrypted cloud sync means the profiles you set up on one machine are available on the next.
Who Uses a Cloud Browser (and What They Do With It)
Anyone juggling more than one identity online benefits from isolated, disposable, or shareable sessions. A few common patterns:
Marketers and advertisers
Managing Meta, Google, and TikTok ad accounts for multiple clients in parallel, reviewing creative side-by-side, and handing a contractor temporary access without ever sharing a password.
E-commerce sellers
Running several storefronts or marketplace accounts without cross-contamination, and blurring P&L or billing pages before looping in a bookkeeper or virtual assistant.
SEO professionals
Checking SERPs from different regions using per-session proxies, and comparing snippet or layout changes across accounts without constant re-authentication.
Developers and QA teams
Spinning up a disposable cloud session to reproduce a bug or open a suspicious link safely, then discarding it — no local VM sprawl required. Teams that need repeatable test runs instead lean on the desktop app’s Automation API to script the same checks with Playwright or Selenium.
Remote workers and everyday users
Keeping work and personal logins cleanly separated, and browsing with less risk on a shared or borrowed device while traveling.
Choosing Between Cloud Sessions and the Sendwin Browser
Since Send.win gives you two modes instead of one, it helps to have a quick rule of thumb rather than defaulting to whichever one you tried first.
- Reach for a cloud session when you’re on a device you don’t fully trust, opening a link you’re not sure about, or need to browse for a few minutes without leaving any trace on the machine in front of you.
- Reach for the Sendwin Browser when you’re managing the same set of accounts every day, need automation via Selenium, Puppeteer, or Playwright, or want your profiles to sync across your own devices without re-creating them each time.
- Use both if your team has a mix of daily operators and occasional contributors — install the desktop app for the core team and hand out cloud sessions for guests, contractors, or one-off reviewers.
Neither mode requires you to pick a side permanently. Because Sendwin Browser profiles sync through encrypted cloud storage, you can start a task on the desktop app at your desk and, if you need to check something quickly from a borrowed device later, fall back to a cloud session without losing continuity on the accounts that matter.
Plans and Pricing
Send.win offers a 30-day free trial with no credit card required, so you can test both the desktop app and cloud sessions before committing to a plan.
- Pro — $9.99/mo ($6.99/mo billed annually): 150 profiles, 5GB of proxy bandwidth, and access to the Automation API for Selenium/Puppeteer/Playwright workflows.
- Team — $29.99/mo ($20.99/mo billed annually): 500 profiles, 20GB of proxy bandwidth, the Automation API, and 16 seats for agencies and larger teams.
Cloud browser sessions draw from a cloud browsing time allowance rather than a flat per-seat fee, so heavy cloud-session users should check current allowances on the pricing page before choosing a plan. Since pricing and included quotas can change, always confirm the latest numbers there rather than relying on any single blog post.

Frequently Asked Questions
What is a cloud browser and how does it work?
A cloud browser is a real browser instance that runs on remote servers instead of your device. You see a streamed view of the page and send clicks and keystrokes back up; the actual page code, cookies, and downloads stay on the provider’s infrastructure, never your local machine.
How is a cloud browser different from an incognito window or a browser profile?
Incognito mode and profiles still run locally and share your device’s underlying context. A cloud browser executes entirely off-device, so there’s no shared local storage, no local cache, and nothing left behind once the session ends.
Do I need to install anything to use Send.win?
It depends on the mode. Cloud browser sessions need no installation at all — you open one from your account and start browsing. If you want the daily-driver desktop experience with automation support, you’ll download the native Sendwin Browser app for Windows, macOS, or Linux.
Is a cloud browser actually more secure than my regular browser?
Yes, for the specific risks it targets. Because page code executes remotely, malicious scripts and drive-by downloads on a compromised site have no local machine to affect. Combined with per-session isolation, it also prevents accidental cookie or login bleed between accounts.
What’s the difference between Send.win’s cloud sessions and the Sendwin Browser desktop app?
Cloud sessions run entirely in the cloud with zero local install and are metered by cloud browsing time — ideal for occasional or install-free use. The Sendwin Browser is a native desktop app that’s local-first with encrypted cloud sync, better suited to daily multi-account work and automation.
Can I automate tasks in Send.win?
Yes. Starting on the Pro plan, Send.win’s Automation API lets you drive Sendwin Browser sessions locally with standard tools like Selenium, Puppeteer, or Playwright, the same way you’d script any desktop Chromium browser.
Does Send.win limit how long I can use a session?
Sendwin Browser sessions aren’t capped by an arbitrary timer — you work as long as your plan allows. Cloud browser sessions draw from a cloud browsing time allowance, so check your plan’s current allowance if you rely heavily on the cloud mode.
How much does Send.win cost, and is there a free trial?
Send.win offers a 30-day free trial with no credit card required. After that, Pro is $9.99/mo ($6.99/mo billed annually) with 150 profiles and 5GB of proxy bandwidth, and Team is $29.99/mo ($20.99/mo billed annually) with 500 profiles, 20GB of bandwidth, and 16 seats. Both plans include the Automation API.
