If you’ve ever wished you could open any website in a fresh, isolated browser that leaves no trace on your computer—and do it without installing anything—this guide is for you. A cloud browser streams a fully functional browser from the cloud to your device. That means you can handle sensitive logins, test campaigns in parallel, and research safely without cross-contaminating cookies, leaking credentials, or risking your laptop.
In this post, you’ll learn how a cloud browser works, why it’s different from extensions or local profiles, and how Sendwin—the cloud browser built for multi-login and privacy—helps teams move faster while staying secure. We’ll cover features, security, use cases, pricing, and a simple “getting started” checklist so you can try it today on send.win.
What Is a Cloud Browser (and Why It Matters)
A cloud browser runs remotely on provider infrastructure and streams the web page to your device. Because the page executes away from your computer, risky code never runs on your machine. This setup—often called remote browser isolation (RBI)—reduces malware and phishing risk by keeping browsing activity separated from your endpoint. In plain language: your device receives a safe stream, not the raw, executable page.
Why it matters:
- No local footprint: Sessions don’t mix or spill cookies onto your device.
- Lower risk: Malicious scripts execute remotely, not on your laptop.
- Easy collaboration: Grant access to a session without handing over the password, and revoke it any time.
Cloud Browser vs. Extensions, Profiles, and VMs
You can juggle multiple accounts with Chrome profiles, incognito windows, or separate browsers. That works—until it doesn’t. Profiles still run locally and can share system context. Incognito isn’t true isolation. Secondary browsers create clutter. And full remote desktops/VMs are heavy to maintain compared to a focused, agentless cloud browser that spins up in seconds.
A cloud browser like Sendwin is built for tab-level isolation and password-free collaboration, streaming real browsers from the cloud so nothing executes on your device. The result is cleaner security and smoother multi-login workflows.
Meet Sendwin: A Cloud Browser Built for Multi-Login & Privacy

Sendwin is a cloud browser for managing multi-login. Each tab is its own isolated browser with its own cookies, cache, storage, IP, and (optionally) proxy. Open several accounts on the same site side-by-side, switch in one click, share a live session with teammates without revealing passwords, and keep everything in sync across devices. Because it’s browser-based, there’s nothing to install. Sign in on the web and launch isolated tabs.
Highlights at a Glance
- Multiple logins made easy Run many accounts in parallel—no more sign-in/out loops, incognito detours, or spare browsers. Teams see big time savings once every login lives in its own tab.
- Session isolation on every tab Tabs never share cookies or local storage, preventing cross-account mishaps and keeping ad ops and marketplace work clean.
- Different browsers in a single window Each tab behaves like a separate profile, without the hassle of managing local profiles.
- Share account, not password Invite collaborators into a live, logged-in session. Add a timer and revoke access any time.
- Premium Proxy add-on (BYO proxy) Attach a proxy per session for accurate geo testing, ad reviews, or regional SEO checks—often more precise than a blanket VPN.
- Protect pages you don’t want to share Blur or block sensitive views (billing, payouts, admin) before sharing a session.
- Session timers Time-box access (e.g., 30 minutes, 1 hour, 24 hours) so least-privilege is easy.
- Privacy by design Tabs don’t use shared storage; other sites or tabs can’t monitor your activity.
- Rock-solid security AES-256 for symmetric operations and RSA-2048 for asymmetric operations across sessions.
- Zero-Trust Browser Isolation Pages execute remotely; your device receives a safe stream—dramatically reducing phishing and malware risk.
- Disposable browsers Create and discard clean sessions in seconds for risky links or one-off tests.
- No client install; nightly updates Launch from the dashboard; cloud images update frequently for compatibility and stability.
- No arbitrary time limits on paid plans Work as much as you want throughout the billing month—no surprise cutoffs.
- Intuitive interface Clean and straightforward for non-technical users, efficient for power users.
- Global endpoints Choose regions in the Americas, Europe, and Asia for low-latency access and location-accurate testing.
How Sendwin Keeps You Safer by Default
Agentless isolation that shields your device
With RBI, the remote browser runs in a protected cloud container or VM. Only a safe visual stream reaches your device, which significantly reduces the chances of drive-by downloads or script-based attacks affecting your machine. You get a strong security baseline without changing how you browse.
Strong encryption and privacy-first design
Sendwin encrypts session data with AES-256 and uses RSA-2048 for asymmetric operations. Tabs are sandboxed, and session data is protected in transit and at rest. Combined with per-tab storage isolation, this prevents cross-tab tracking and cookie bleed.
Real browsers on real machines
Unlike emulated browsers that can break compatibility, Sendwin streams real desktop browsers running on virtual machines. That means fewer weird rendering issues and smoother experiences across ad platforms, analytics tools, marketplaces, and web apps.
Productivity Wins: Multi-Login Without the Headaches
Switch accounts with one click
Pin and name tabs per client or project (e.g., “ACME – Meta Ads,” “ACME – Google Ads,” “ACME – Shopify”). Jump between them instantly, keep identities stable, and avoid accidental edits under the wrong account.
Test creative faster
Session isolation lets you open multiple ad accounts or storefront variants in parallel. Compare copy, creative, and pricing side-by-side—without re-auth prompts or cookie collisions slowing you down.
Collaborate without sharing credentials
Need a teammate to fix a pixel, check a bid, or reconcile a payout? Share the live session link, set a timer, blur billing pages, then revoke when done. The password stays private.
Bring your own network identity
Per-session proxies keep IP and location consistent for reviews, QA, and localized SEO checks—no system-wide VPN required. It’s a more precise way to control attribution and avoid signal mixing.

Feature Deep Dive (What You Get, Why It’s Useful)
Multiple logins made easy
Every project gets its own clean browser tab. Once you stop juggling profiles and re-auth prompts, the daily productivity boost is obvious—in many teams, the multi-login “wall” simply disappears.
Session isolation on every tab
No shared local storage means no cookie carryover. You can open the same site in two tabs under different accounts and work normally, with zero cross-mixing.
“Different browsers” in a single window
Realistically, you no longer need separate browsers or a profile zoo. Each tab behaves like a dedicated browser profile—but runs remotely, so it never touches your machine.
Premium Proxy add-on (BYO proxy)
Attach per-tab proxies for regional tasks—ad reviews, market checks, affiliate QA. This is more granular (and often more reliable for attribution) than a broad VPN.
Protect every session page (blur/block)
Before sharing, hide sensitive pages or elements—think billing, payouts, or admin settings—so reviewers see only what they need.
Share account, not password
Let teammates work inside the logged-in session with one click. Add a timer and blur or block pages you don’t want exposed. You keep control; they get work done.
Session timer (access windows)
Define how long someone can use the session: 30 minutes, 1 hour, 24 hours—you choose. It’s least-privilege access designed for real-world workflows.
Privacy you can feel
No shared storage across tabs means other tabs and websites can’t monitor your activity. Combined with isolation, you get a strong privacy baseline without extra effort.
Rock-solid security (AES-256 + RSA-2048)
Industry-standard cryptography protects session data—combined with sandboxed tabs and zero-trust execution to minimize risk.
Zero-Trust Browser Isolation
Pages execute remotely and stream to you, which dramatically reduces exposure to phishing and malware. You keep your endpoint clean without changing your browsing habits.
Disposable browsers
One-off test? Unknown link? Create a session, do the work, dispose of it. Fast, safe, and clean.
Intuitive interface
Sendwin is simple and friendly for non-technical users yet powerful for experts. The learning curve is short; the productivity benefits are immediate.
Global endpoints (Americas, Europe, Asia)
Pick the closest region for low latency or the right region for geo-specific tasks. It’s ideal for teams operating across countries and time zones.
