The antidetect browser
for running multiple accounts
Parallel gives every account its own isolated browser profile with a unique, coherent fingerprint — proxy, cookies, canvas, fonts, the works. Built for anyone managing multiple accounts: social, ads, marketplaces, or your own automation.
3 profiles free, forever. No account limit games — licence more only if you need them. · Latest v0.0.00
Windows may show a security warning — here's why
Create your free account
Three profiles free, forever. No card.
Sign in to manage profiles, proxies and your team from any browser. Opening a profile needs the app.
What a real antidetect browser needs
Three questions worth asking of any of them: does it really keep accounts apart, can it run a hundred without becoming a chore, and is the account holding all of it worth trusting.
Keeping accounts apart
Coherent fingerprints
Every profile gets a consistent, deterministic identity — canvas, WebGL, audio, fonts, timezone and UA all agree with each other. A contradiction between them is what gets a profile flagged, so they are generated together rather than spoofed one at a time.
Built-in proxy manager
HTTP, HTTPS, SOCKS4 and SOCKS5, pasted in whatever format you already have. Test one to see its real exit IP and country before you rely on it, and assign a pool across profiles at random, round-robin, or one each.
Sessions that follow you
Cookies are encrypted with your own key and synced, so a profile signed into an account on one machine is signed in on the next. A lock stops the same profile being open in two places — which is what would otherwise cost you the login.
Ten accounts per profile
A persona is not one login. Keep up to ten platform accounts on a profile, each with its own saved username and password, each opening in its own tab. The password is typed into the login page for you — and never submitted, because an automatic login attempt on every launch is what trips a challenge.
Running a lot of them
Built for hundreds, not three
Create profiles in bulk with name patterns, organise them with groups and tags, and launch, stop, move or delete dozens at once. Search and filter instead of scrolling.
Automation, three ways
A no-code RPA builder with scheduling for work you can describe in advance. A token-gated local API that hands your own Puppeteer or Playwright script a real CDP endpoint. And an AI assistant you can just ask — Claude opens a profile, reads the page, clicks and types, using that profile’s own fingerprint, proxy and logins without ever handling a credential.
Window syncing
Open several profiles, act in one, and it happens in all of them — typing, clicking, scrolling, navigation. For the work you cannot script because you are reading the page as you go.
The account it all hangs off
Your account, actually protected
Two-factor authentication with recovery codes, a sign-in history, and an email the moment your account is opened from somewhere new. Your account holds the sessions for every profile you run — one stolen password should not be every account you own.
A delete you can undo
Profiles go to the trash for 30 days, fingerprint and browser session intact. Restore one and it is still signed in to whatever it was signed in to.
Hand a profile to someone
Send a profile to another Parallel account — fingerprint, proxy, session and logins — encrypted to their device before it leaves yours. Or export an encrypted file. Either way nobody in between can read it, including us.
Extensions and per-profile settings
Load your own unpacked extensions into the profiles that should carry them. Require a working proxy before a profile opens, block video to save metered traffic, push bookmarks onto new profiles, or feed a video file in as the webcam.
A team, with real boundaries
Up to five people on a paid account, each with their own login and role. Grant access by group or by individual profile, cap how many profiles each person can hold, and see who changed what.
Automate every profile with no-code RPA
Build a process once — visually, no scripting — and run it on any profile: log in, fill a form, scroll a feed, click through a checkout. Every automation runs through the same isolated, fingerprinted browser as a normal launch, so it's indistinguishable from you clicking it by hand.
- Visual step builder — drag together clicks, typing, navigation, and waits, no code
- 57 commands — CSS & XPath selectors, tabs, cookies, screenshots, file & Excel I/O, network listeners, raw JS
- Conditionals & four loop types — if/else on 14 condition kinds, loop by count, by element, over data, or while — nested as deep as you need
- Scheduling — run a process unattended once, on an interval, daily, weekly, or monthly, with no browser window open
- Built-in integrations — Google Sheets, 2Captcha, OpenAI, IMAP inboxes, and 2FA codes, all keyed locally and never synced
- Debug mode & run history — pick the profile at launch, then replay exactly what happened, step by step
- Import/export & cloud sync — share a process as JSON, or sign in anywhere and it's already there

Frequently asked
Windows says “Windows protected your PC” — is that safe?
Yes. That's Microsoft Defender SmartScreen, and it appears because Parallel isn't code-signed yet — a signing certificate is an ongoing cost we haven't taken on while the app is new. It's a warning about an unrecognized publisher, not about anything detected in the file.
To install:
- Click More info on the blue dialog.
- Click Run anyway.
If you'd rather verify the download first, every release publishes the installer's
SHA-256 hash — compare it against
the published checksum
by running Get-FileHash .\Parallel-Setup-<version>.exe in PowerShell.
Matching hashes mean the file is exactly what we built.

What is an antidetect browser?
A browser that runs each account in its own isolated profile, so the sites you visit can't tell they belong to the same person. Every profile gets its own cookies, storage and cache — and its own device fingerprint: the canvas, WebGL, fonts, screen, timezone and language signals a site reads to identify a visitor beyond their login. Bind a separate proxy to each and the accounts have nothing in common to correlate. The point isn't hiding that a browser is a browser; it's that two profiles look like two ordinary, unrelated people.
You will see the same thing called an anti-detect browser, an anti detect browser, a multi-login browser or a browser profile manager — they all describe this, and the spelling varies more than the software does.
What platforms are supported?
Windows today. Updates are opt-in — when a new version is available the app shows an “Update to” button in the top bar, and nothing downloads or installs until you click it.
Why crypto only, no card?
Card processors aren't available to us in every region yet. Crypto works everywhere and settles directly — we're working on adding card payment.
What happens when a licence expires?
Starter, Pro and Scale are licences with a term — one month, six months or a year. You are emailed a key and activate it in the app. Nothing auto-renews and no card is stored: when a licence runs out you keep your account and your data, and profiles over the free limit are frozen until you renew rather than being deleted.
Can I use my own automation scripts?
Yes — a local, token-gated HTTP API lets you start a profile and get a real CDP WebSocket endpoint to connect Puppeteer, Playwright, or anything else that speaks the Chrome DevTools Protocol.
Do my profiles sync across machines?
Yes — sign in with the same account on another machine and your profiles/proxies pull down automatically. Launch state itself is per-machine.
