What Is Send.win? A Quick Overview
Send.win is a multi-login (anti-detect) browser built for anyone who needs to run more than one account on the same website at the same time — safely, and without triggering bans. Instead of juggling incognito windows, secondary browsers, or a pile of browser profiles that all still share the same underlying fingerprint, Send.win gives every profile its own isolated cookies, local storage, and browser fingerprint (canvas, WebGL, fonts, timezone, and more), plus a built-in proxy option so each profile can look like it’s coming from a genuinely different device and location.
This guide replaces our old 2022 install walkthrough. Send.win has changed a lot since then — it now ships as a native Desktop app for Windows, macOS, and Linux, plus fully cloud-hosted browser sessions you can run with zero local install, and Team-plan users get access to an Automation API that plugs directly into Selenium, Puppeteer, and Playwright. Below, we’ll cover what Send.win actually does, how to run a cloud browser session in every major browser, how to set up the desktop app, and how to get your first isolated profile running in under five minutes.
Why You Need a Multi-Login Browser in 2026
If you’ve ever tried to manage two Instagram accounts, run parallel ad accounts for different clients, or test a website while logged in as both an admin and a regular user, you already know the pain: browsers are built around the assumption that you only have one identity per device. Every tab you open shares the same cookies, the same fingerprint, and the same IP address unless you go out of your way to change that.
That single-identity assumption is exactly what platforms like Facebook, Amazon, TikTok, and Google use to link accounts together and flag them for suspicious activity. Opening a second account in an incognito tab doesn’t fix this — your device fingerprint, fonts, screen resolution, and often your IP address are still identical across both sessions, so the platform can still connect the dots.
A dedicated multi-login browser solves this at the root by generating a distinct, consistent fingerprint per profile and keeping each profile’s storage completely separate. Send.win takes this further by bundling proxy management, team sharing, and automation support into the same tool, so you’re not stitching together three or four separate apps just to run a handful of accounts safely.
Send.win Core Features at a Glance
| Feature | What It Does |
|---|---|
| Unique fingerprint per profile | Each profile gets its own canvas, WebGL, font, timezone, and hardware fingerprint so platforms can’t correlate accounts |
| Isolated sessions | Cookies, cache, and local storage never bleed between profiles — log into five accounts on the same site with zero cross-contamination |
| Built-in proxy support | Attach residential, datacenter, or mobile proxies directly to a profile so IP and fingerprint stay consistent together |
| Team sharing | Share individual profiles/sessions with teammates without ever handing over the underlying password |
| Cloud browser sessions | Run an isolated profile entirely in the cloud from Chrome, Firefox, or Edge — no install required |
| Native Desktop app | A standalone Windows/macOS/Linux client for users who want a dedicated, always-available profile manager outside the browser |
| Automation API | Selenium, Puppeteer, and Playwright integration for scripted, headless, or QA workflows (Team plan) |
How to Install Send.win in Google Chrome
Chrome is the most common starting point — and since Send.win doesn’t ship as a Chrome extension, the fastest way in is a cloud browser session that runs with zero local install:
- Open Chrome and go to send.win.
- Click Sign up or Log in to reach your dashboard.
- Click Launch Cloud Session to start a fully cloud-hosted profile — it opens directly inside a new Chrome tab.
- Sign in inside the session, and you’ll land on your profile dashboard.
- Prefer running profiles locally instead? Click Download from the same dashboard to install the native Sendwin Browser desktop app for Windows, macOS, or Linux.
From here you can create your first isolated profile, assign it a proxy, and start browsing without touching your main Chrome identity.
How to Install Send.win in Microsoft Edge
Edge is Chromium-based, so a Send.win cloud session behaves identically once you’re signed in — there’s no separate Edge add-on involved:
- Go to send.win in Edge.
- Click Sign up or Log in.
- From your dashboard, click Launch Cloud Session to open an isolated profile running entirely in Send.win’s cloud — nothing downloads to your machine.
- Sign in inside the session, and you’re ready to create your first profile.
If you’d rather manage profiles locally, the Sendwin Browser desktop app covered below installs like any standard Windows, macOS, or Linux application.
How to Install Send.win in Mozilla Firefox
Firefox runs a Send.win cloud session the same way as any modern browser — there’s no Firefox add-on to find or install:
- Visit send.win in Firefox.
- Click Sign up or Log in.
- Click Launch Cloud Session to start an isolated, cloud-hosted profile directly inside a Firefox tab — nothing to install.
- Sign in inside the session, and start creating profiles.
One thing worth knowing: Firefox’s own Multi-Account Containers extension solves an overlapping but narrower problem — it only isolates cookies inside Firefox, while Send.win’s cloud sessions isolate the full fingerprint and work consistently across every browser you use.
Installing the Send.win Desktop App
Beyond running cloud browser sessions with zero local install, Send.win also ships as a native Desktop app for Windows, macOS, and Linux (Sendwin Browser). This is the option most agencies, e-commerce sellers, and teams running dozens of profiles end up using day to day, because it doesn’t depend on any single browser being open and it’s built specifically to manage large numbers of isolated profiles at once.
- Go to send.win/download (the “Download” link is the first item in the site’s top navigation).
- Choose the installer that matches your operating system — Windows, macOS, or Linux.
- Run the installer and follow the on-screen setup steps.
- Launch the app and sign in with the same account you use for cloud browser sessions — your profiles sync automatically.
- Create, launch, and organize profiles directly from the desktop dashboard, complete with folders, tags, and bulk actions for larger profile counts.
Because the desktop app and cloud browser sessions share the same account, you can start a session in the cloud at your desk and pick it up later from the desktop app on a different machine without losing any cookies or login state.
Setting Up Your First Profile After Install
Once Send.win is set up (cloud session, desktop app, or both), getting your first working profile takes just a few steps:
- Create a new profile. Give it a name (e.g., “Instagram – Client A”) so it’s easy to find later.
- Choose a fingerprint configuration. Send.win auto-generates a realistic, consistent fingerprint, or you can fine-tune the operating system, browser version, screen resolution, and timezone shown to websites.
- Attach a proxy (optional but recommended). Send.win supports residential, datacenter, and mobile proxies out of the box, and matching your proxy’s location to your fingerprint’s timezone is one of the biggest factors in avoiding flags.
- Launch the profile. A new isolated window opens with its own cookies and fingerprint — log into your account exactly as you normally would.
- Save and reuse. The profile stays saved for next time; closing it doesn’t log you out or clear its cookies.
If you’re managing dozens of accounts across a team rather than just a couple for yourself, our step-by-step walkthrough on how to create sessions in Send.win’s cloud browser goes deeper into naming conventions, folders, and bulk profile creation. And if proxies are new to you, the dedicated guide on how to add a proxy to any session covers residential vs. datacenter vs. mobile proxies and how to match them to your use case.
Sharing Profiles With a Team
Solo users can stop here, but if you’re working with a team — virtual assistants, agency staff, or co-founders — Send.win lets you share individual profiles without ever handing over the actual account password. You control who has access, and you can revoke it instantly if someone leaves the team. This is a common upgrade path once a single-user setup grows into a small operation, and it pairs naturally with the Automation API below once a team starts scripting parts of its workflow.
Send.win Automation API: For Developers and QA Teams
If you work in QA testing, web scraping, or ad verification, manually clicking through dozens of profiles doesn’t scale. That’s what the Automation API is for — it’s included on the Team plan and lets you drive Send.win profiles programmatically through the frameworks most engineering teams already use:
- Selenium — connect to a Send.win profile’s browser instance the same way you’d connect to any remote WebDriver session
- Puppeteer — attach over the DevTools protocol to script navigation, form fills, and scraping against an isolated fingerprint
- Playwright — run cross-browser automated test suites against real, fingerprinted profiles instead of a single shared headless instance
This matters because most anti-bot systems are specifically tuned to catch generic headless browser fingerprints. Running your automation scripts through a Send.win profile with a proxy attached gives each automated session a distinct, realistic fingerprint instead of the flat, easily-flagged signature that a bare Selenium or Playwright instance produces.

Troubleshooting Common Installation Issues
My cloud browser session doesn’t load
Cloud sessions run inside a regular browser tab rather than a separate extension, so there’s no icon to pin. If a session doesn’t load, refresh the tab, confirm you’re logged into the correct Send.win account, and check that your cloud browsing time or saved session limit for your plan hasn’t been reached.
Send.win won’t launch a profile
Check that your browser is fully up to date — older browser versions can occasionally block the web technologies cloud sessions rely on. Restarting the browser after an update usually resolves this immediately.
A proxy attached to a profile isn’t connecting
Double-check the proxy credentials (host, port, username, password) were entered exactly as provided by your proxy vendor, and confirm the proxy hasn’t expired or hit its data cap.
The desktop app and a cloud session show different profiles
Make sure you’re logged into the same Send.win account on both. Profiles sync per-account, so a mismatched login is the most common cause of this.
Corporate or managed devices block software installs
Some organizations restrict new application installs via IT policy. In that case, running a Send.win cloud browser session is often the more reliable path, since it works entirely inside a browser tab with nothing to install locally, unlike the native Desktop app.
🏆 Send.win Verdict
If you need to run more than one account on the same platform — safely, consistently, and without babysitting a pile of browser windows — Send.win is the most complete tool for the job. It runs instantly in Chrome, Firefox, or Edge through zero-install cloud browser sessions, backs that up with a native Desktop app for heavier profile management, and scales all the way up to a full Automation API for teams running Selenium, Puppeteer, or Playwright. Few multi-login tools cover this entire range from casual single-user setups to team-scale automation in one product.

Frequently Asked Questions
Is Send.win free to use?
Send.win offers a 30-day free trial with no credit card required, so you can install it and test it fully before committing to a paid plan. After the trial, paid plans start at $9.99/mo for Pro.
Does Send.win work on Mac and Linux, or just Windows?
Yes. The native Desktop app (Sendwin Browser) has dedicated installers for Windows, macOS, and Linux, and cloud browser sessions run entirely inside any modern browser, so they work the same way on Mac and Linux as they do on Windows.
Do I need the Desktop app if I’m already using cloud browser sessions?
No, they’re not mutually exclusive but also not required together. Cloud browser sessions are enough for casual or single-device use. The Desktop app is better suited to managing a large number of profiles, running Send.win without keeping a browser tab open, or working across multiple machines.
Will using Send.win actually stop my accounts from getting banned?
No tool can offer a 100% guarantee, since platforms constantly update their detection methods and account bans can also happen for reasons unrelated to fingerprinting (like policy violations). What Send.win does is remove the single biggest technical signal — a shared fingerprint across multiple accounts — that platforms use to link and flag accounts in the first place.
What’s the difference between Send.win and just using Incognito mode?
Incognito mode clears cookies when you close the window, but it does not change your browser fingerprint, screen resolution, fonts, or IP address. Two incognito sessions on the same device still look identical to a website’s fingerprinting script. Send.win generates a genuinely distinct fingerprint per profile, which incognito mode cannot do.
Can I use my own proxies with Send.win, or do I have to buy Send.win’s?
You can attach your own residential, datacenter, or mobile proxies to any profile, or use proxy bandwidth included in your Send.win plan. Both options are supported from the same profile settings panel.
What is the Automation API and who actually needs it?
The Automation API lets you control Send.win profiles programmatically using Selenium, Puppeteer, or Playwright. It’s aimed at QA engineers running automated test suites, teams doing web scraping, and anyone verifying ads or site behavior at scale where manually clicking through profiles isn’t practical. It’s included on the Team plan.
How many profiles can I run at once?
This depends on your plan — Pro includes 150 profiles and Team includes 500, both with the option to add more profiles individually at $0.05 each if you need to go beyond your plan’s included amount.
Is installing Send.win difficult for a non-technical user?
No. Starting a cloud browser session just takes signing up and clicking Launch — there’s nothing to install. If you prefer running profiles locally, the Desktop app installs like any standard Windows, macOS, or Linux application. No coding or technical configuration is required to create and use your first profile.
