If you research sensitive topics, run multiple accounts, or simply don’t want to leave a trail across the web, a cloud browser is the smarter way to stay private. Instead of running pages on your laptop, a cloud browser executes everything remotely and streams a safe, interactive view to you—like controlling a live screen share. Your device never executes the page’s code. Your sessions can be encrypted, disposable, and non-attributable—and you can do it without installing a VPN.
In this guide, you’ll learn how Sendwin—an anonymous, privacy-first cloud browser for multi-login—works, how it differs from extensions and traditional browsers, who it’s for, what it costs, and how to get started in minutes.
What Is an Anonymous Cloud Browser?
A cloud (or remote) browser runs in an isolated virtual machine and streams pixels to your device. Cookies, cache, scripts, and downloads are contained away from your computer, so nothing executes locally. That means strong resistance to malware and phishing, fewer local artifacts, and the ability to spin up clean, disposable sessions on demand.
Unlike a VPN—which just tunnels traffic from the same local browser—cloud browsing moves execution off your device entirely. With Sendwin, each tab is its own isolated browser in the cloud, protected by AES-256 (symmetric) and RSA-2048 (asymmetric) cryptography, and built on a zero-trust model that avoids shared storage between tabs.
Why Sendwin?
Sendwin is a cloud browser to manage multi-login—a browser-based version of Sendwin that runs each login in its own isolated tab, with no extension or local install required. It’s built to help teams and power users switch accounts safely, share sessions securely, and work from multiple regions with bring-your-own proxies.
What makes it “anonymous”?
- Remote execution: Your laptop never runs page code; you control a safe video-like stream.
- Per-tab isolation: No shared storage between tabs prevents cookie bleed and cross-site monitoring.
- Encryption: AES-256 for data and RSA-2048 for key exchange.
- IP/Location controls: Point sessions at global endpoints (Americas, Europe, Asia) or assign your own proxies.
Key Security & Privacy Architecture (In Plain English)
Zero-Trust Browser Isolation
Assume every page could be hostile. Never let it execute locally. Stream only the result. This sharply reduces exposure to malware, phishing, and drive-by exploits and makes risky research safer.
Strong, Modern Cryptography
Sessions use AES-256 and RSA-2048. In practice, you get end-to-end protection for session data and keys, without local cookie or cache residue.
No Shared Storage
Sendwin’s browser tabs do not share storage. Each tab is a siloed environment, ideal for multi-login, ad ops, and agency work where clean separation is a must.
Real Browsers on Real Virtual Machines
No emulators. Sendwin runs real, custom desktop browsers on virtual machines for accurate behavior and compatibility.
Sendwin Features (What You Can Actually Do)
Multiple logins—minus the mess
Open two, ten, or a hundred accounts at once—each in its own isolated tab. No more logging in and out or juggling secondary browsers.
Session isolation on every tab
Each tab behaves like a separate browser profile, so cookies, cache, and storage never bleed between accounts. It’s perfect for testing copy variations side-by-side or separating client workspaces.
Different browsers in a single window
Switch among real browser engines for compatibility checks and debugging—in the cloud.
Premium Proxy add-on (Bring Your Own Proxy)
Assign a proxy per session for location testing, ad verification, or regional SEO checks—no VPN client required.
Protect every sensitive page
Blur or block billing pages and account settings before you share. You can also set session timers (e.g., 30 minutes, 1 hour, 1 day) to auto-revoke access on schedule.
Share accounts, not passwords
Generate time-boxed, encrypted links that give teammates temporary access—without exposing credentials. Revoke access anytime.
We protect your privacy
Sendwin doesn’t use shared storage between tabs; other tabs and sites cannot monitor your activity via shared local data.
Rock-solid security
AES-256 + RSA-2048 + isolation streaming for every session. Security is baked in by default.
Switch accounts with one click
Jump between sessions instantly with clean separation—no private windows, no throwaway profiles, no secondary browsers.
IP/Location anonymity (no client or VPN install)
Launch from global endpoints—Americas, Europe, Asia—or attach your own proxies. There’s nothing to install on your device.
Nightly version updates
Sendwin keeps engines current so your sessions look and behave like normal, up-to-date browsers—no maintenance on your end.
Isolation from malware/phishing
Because code doesn’t run locally, agentless sessions stream pixels rather than executing page scripts on your laptop.
Disposable browser sessions
Spin up a clean environment for testing and destroy it in seconds. Great for QA, growth experiments, and risky research.
Safe browsing sandbox
Everything runs in isolated infrastructure, reducing the risk of infection by trojans or malicious extensions.
No time limit mid-workflow
On paid plans, you won’t hit per-session countdown timers that interrupt work; use your monthly allocation flexibly.
Intuitive interface
A clean, simple dashboard makes cloud browsing approachable—even for non-technical teammates.
Global endpoints
Choose Americas, Europe, or Asia for lower latency and accurate geo testing.

Cloud Browser vs. Extensions/VPNs: What’s the Difference?
| Question | Traditional Browser + VPN | Multi-Login Extension | Sendwin Cloud Browser |
|---|---|---|---|
| Where does code run? | Locally | Locally | Remotely (agentless streaming) |
| Per-tab isolation? | Limited | Often profile-based | Every tab isolated by design |
| Local artifacts? | Yes (cookies/cache) | Yes | No local execution or shared storage |
| Easy, safe sharing? | Risky (passwords) | Risky (profile export) | Share sessions, not passwords; time-boxed links |
| Geo/IP control? | VPN tunnel | Proxy add-ons | BYO proxies + global endpoints |
| Maintenance | Manual updates | Extension limits | Nightly updates, no client install |
Bottom line: If your goals are privacy, compartmentalization, and team collaboration, a cloud browser aligns better than a local browser plus VPN.

FAQs: Anonymous Cloud Browsing with Sendwin
Do I still need a VPN?
Not for Sendwin usage. Because pages run remotely and stream to you, your local device isn’t the browser of record. You can also attach BYO proxies or pick global endpoints for location testing—no VPN client required.
Does Sendwin “block trackers”?
Sendwin reduces common tracking vectors by isolating tabs, avoiding shared local storage, and running code remotely. Tracking can’t be eliminated entirely, but per-session proxies and remote execution make it much harder to correlate your activity.
Is it really encrypted?
Yes—AES-256 for symmetric operations and RSA-2048 for asymmetric key exchange are standard across Sendwin sessions.
What about malware and risky sites?
Because your endpoint never executes page code, Sendwin’s agentless streaming helps protect you from malware and phishing attempts.
Are these real browsers?
Yes—Sendwin runs real browsers on VMs, not emulators, so sites behave normally and fingerprints look natural.
Will I hit session timeouts?
Paid plans do not impose per-session countdown timers that cut you off mid-flow; use your monthly allocation as you like.
