The Sendwin desktop browser
A downloadable anti-detect browser for Windows, macOS and Linux. Every profile is a fully isolated, Chromium-based browser with its own fingerprint, proxy, cookies and storage, running locally on your machine and powered by the Sendwin Stealth Engine.
Isolated local profiles
Every profile is a self-contained Chromium-based browser with its own cookies, local storage, history and login state — so there is zero bleed-over between accounts. Create up to 10 profiles on Free, 150 on Pro and 500 on Team, organize them into folders, and open as many side by side as your plan allows.
Sendwin Stealth Engine
Each profile is given a coherent, real-looking device identity. Canvas, WebGL, audio, installed fonts, hardware, timezone and User-Agent client hints are all spoofed together at the engine level, so a site sees a distinct physical device rather than one machine running many logins.
A proxy per profile
Assign a dedicated proxy to each profile. Use Sendwin's built-in residential pool (1 GB on Free, 5 GB on Pro, 20 GB on Team) or bring your own HTTP/SOCKS proxy. The built-in tester sends a live request and shows the real exit IP, country and latency before you launch — so a bad proxy never touches your account.
Cookies & per-profile 2FA
Import and export cookies as JSON to move sessions in or out, and store a TOTP two-factor secret per profile so your current authenticator code is always one click away inside the profile. Both stay on your own machine.
Bulk create
Paste a list of proxies plus a naming template (OS, browser, country, prefix) and spin up dozens of ready-to-use profiles at once, each paired 1:1 with a proxy — instead of building them one by one.
Automation & the Synchronizer
Team plans expose a local Automation API so you can drive profiles with Selenium, Puppeteer or Playwright over the standard CDP endpoint. The Synchronizer broadcasts the same click, type or navigation across many running profiles at once, with a live thumbnail grid.
The Sendwin cloud browser
Run your profiles on Sendwin's servers and stream the live browser to your screen — no local resources or install needed. Ideal for lightweight devices, keeping profiles online around the clock, and sharing a live session with a teammate.
Run any profile in the cloud
Sync a profile and launch it in the cloud with one click. The browser runs on a Sendwin server and streams live to your screen, keeping the same fingerprint and proxy — no local CPU, RAM or install required to use it.
EU & US regions
Cloud sessions run on European and US nodes, so you can place a session close to the region you're operating in for a more natural, lower-latency footprint.
Persistent sessions
Saved cloud sessions keep their cookies and logins for 28 days of inactivity. Close the tab and reopen later — you land right back in your logged-in accounts instead of starting over.
Your daily cloud time
Free includes 10 minutes of cloud time per day and one saved session. Pro and Team get unlimited cloud minutes, with 20 and 100 saved sessions and up to 3 and 9 running at the same time respectively.
Encrypted cloud sync
Push local profiles up to the cloud — 20 synced profiles on Pro, 100 on Team. Profiles are encrypted on your device before they are uploaded, so your cookies and session data are never exposed in transit.
Share a live session
Hand a saved cloud session to a teammate or another user — Pro can share 20 sessions and Team 50. The person you share with opens the same live browser in their own tab, which is perfect for handoffs and collaboration.
Use the desktop browser when…
- You want the strongest, engine-level fingerprint protection.
- You need unlimited run time and full local control.
- You automate with Selenium, Puppeteer or Playwright.
- You run large numbers of profiles at once on your own hardware.
Use the cloud browser when…
- You're on a Chromebook, tablet or locked-down machine.
- You want a session to stay online after you close the tab.
- You need to hand off or share a live session with a teammate.
- You want to operate from a specific EU or US region.
Frequently asked questions
Everything about the desktop and cloud browsers, plans, proxies and security.
Sendwin is an anti-detect browser that comes in two forms that share one account: a downloadable desktop browser for Windows, macOS and Linux, and a cloud browser you run from any device. Both let you operate unlimited isolated profiles — each with its own fingerprint, proxy, timezone and cookies — powered by the Sendwin Stealth Engine.
The desktop browser runs profiles locally on your own machine with engine-level fingerprinting — best for maximum stealth, unlimited run time, automation and full local control. The cloud browser runs the same profiles on Sendwin's servers and streams them to your screen — best when you're on a low-powered device, want a session to stay online, or need to share a live session. You can sync a local profile and open it either way.
Create a free account, then download the desktop build for your operating system, install it and sign in with your browser. Your 30-day free trial starts automatically — no credit card required. You can also launch cloud sessions from the portal at portal.send.win.
The desktop browser runs natively on Windows, macOS (both Intel and Apple Silicon) and Linux. The cloud browser needs no install at all — it streams to any modern browser, so you can use it from a Chromebook, tablet or a machine where you can't install software.
No. Because installers are still being notarized, your OS may show an "unidentified developer" or SmartScreen prompt the first time. On macOS, right-click the app and choose Open, then confirm. On Windows, click "More info" then "Run anyway." After the first launch it opens normally.
The Sendwin Stealth Engine gives every profile a consistent, realistic device identity. Canvas, WebGL, audio, fonts, hardware, timezone and User-Agent client hints are spoofed coherently — derived from a base device and the profile's proxy IP — so profiles look like separate real machines instead of one device running many logins. Pair each profile with its own proxy to keep accounts fully isolated.
Yes. Open as many profiles as your plan allows side by side — each is a fully separate environment with its own cookies and storage, so there's no bleed-over between accounts. On the cloud browser you can run up to 3 sessions at once on Pro and 9 on Team.
You assign a proxy per profile. Use Sendwin's built-in residential pool (1 GB of traffic on Free, 5 GB on Pro, 20 GB on Team) or add your own HTTP/SOCKS proxies in the proxy manager. Every proxy can be tested with one click, which shows the live exit IP, country and latency. Pro and Team can top up residential traffic at $6/GB.
Yes. You can import and export cookies as JSON to move logged-in sessions in and out, and store a TOTP two-factor secret per profile so the current code is always available in the editor. Both live locally on your machine.
Run-in-cloud takes a synced profile and launches it on a Sendwin server instead of your computer, streaming the live browser to your screen. It keeps the same fingerprint and proxy, uses none of your local resources, and stays reachable from any device. Saved cloud sessions keep their logins for 28 days of inactivity.
Yes. Team plans include seats (6 on Pro, 16 on Team) and you can share saved cloud sessions with teammates or other users — 20 shares on Pro and 50 on Team. Whoever you share with opens the same live session in their own browser, so handoffs don't require passwords to change hands.
Yes, on Team plans. The desktop browser can expose a token-guarded local endpoint that returns a standard CDP connection, so you can drive profiles with Selenium, Puppeteer or Playwright while keeping each profile's fingerprint and proxy. The Synchronizer can also broadcast the same actions across many running profiles at once.
Every account starts with a 30-day free trial of the full product — no credit card required. After the trial you can continue on the Free plan (10 profiles, 1 cloud session, 10 cloud minutes/day) or upgrade to Pro ($9.99/mo) or Team ($29.99/mo) for more profiles, unlimited cloud time, sync, sharing and team seats.
Free: 10 local profiles, 1 residential-proxy GB, 1 saved cloud session and 10 cloud minutes a day. Pro ($9.99/mo): 150 profiles, 5 proxy GB, 20 cloud sessions (3 at once), unlimited cloud minutes, 20 synced profiles and 6 seats. Team ($29.99/mo): 500 profiles, 20 proxy GB, 100 cloud sessions (9 at once), 100 synced profiles, 16 seats and the automation API. See the full comparison on the pricing page.
By default your profiles, cookies and session data live on your own machine. Nothing is uploaded unless you enable cloud sync, and profiles are encrypted on your device before they leave it. You can also block a profile for privacy. Your Sendwin account itself supports email verification and two-factor authentication.
Start with the guides above, and if a proxy fails the tester will tell you the exit IP and latency so you can swap it. For anything else, email [email protected] and a real person usually replies within a few hours.
