Free plan · unlimited profiles

Every account in its own browser

Separate profiles with their own proxy, fingerprint and cookies — all in one window.

Closed beta — invites go out in batches. Have a code? Create account

Three Liminal profiles — a social feed from Paris, an ad account from Berlin and a store from Los Angeles, each with an address of its own — come together into one window with a sidebar, where a click switches between them, and the store’s profile shows what it carries: its connection and what sites see, a fingerprint that matches its proxy, its saved accounts and a script that opens it.

Everything a profile needs, in one window

Websites link accounts that share a browser — even through a VPN. In Liminal each profile is a browser of its own.

  • All your profiles in one window

    Open several profiles at once and switch between them without restarting.

  • A proxy or VPN for each profile

    See what sites will see before you work: the address, the location and the time zone.

    The Connection sheet of a profile: the connection works, and what sites will see — the IP address, the location and the time zone.

  • Looks like one real device

    Screen, fonts, WebGL and timezone are generated together and match the location of the profile’s proxy.

    A profile’s fingerprint: the system, the language, the time zone, the screen and the graphics, matching its proxy.

  • Saved accounts

    A profile opens signed in: no passwords to pass around.

    A profile’s saved accounts, each of them signed in.

  • Work on profiles as a team

    Invite people into your workspaces and choose which folders each of them sees and what they may do.

    A team of three people with the roles Admin, Member and Viewer.

  • Automation through the Local API

    Scripts open and drive profiles through a local API — with Puppeteer, Playwright or Selenium.

    A script that connects Puppeteer to a running profile.

  • No limit on profiles

    The Free plan has no limit on profiles. Pro adds sync and built-in proxies, Team adds roles.

    A dozen profiles and the New Profile button.

Three steps to your first profile

  1. Create a profile

    One click, no form to fill. A fingerprint that fits is generated for it.

    A new profile named Shop Canada, its fingerprint generated for it.

  2. Add a proxy

    Use your own, or a built-in one on Pro and Team. Timezone and language follow it.

    A Canadian proxy chosen for the profile from the list of working connections.

  3. Open and work

    Profiles run side by side in one window, each with its own tabs and the cookies of its saved accounts.

    The profile Shop Canada open, with a store’s page in its tab.

FAQ

Questions before you start

Yes. The free plan has no profile cap: unlimited profiles, generated fingerprints, full isolation, and proxy binding, with no card and no trial clock.

Manual fingerprint editing, cloud sync, built-in proxies and team roles are on the paid plans — that is how the free plan is paid for. Everything listed above stays free.

Liminal is built on real Chromium — not an emulator. The TLS fingerprint, the JavaScript APIs, and the browser's behavior are those of Chrome, and the built-in validator checks that a profile's fingerprint parameters are coherent with each other and with its proxy.

No browser can promise that a given site will never flag a given account: detection also depends on your proxy, your account history, and how you use it. What Liminal controls is the browser identity, and it keeps that consistent.

What a running profile holds — history, saved passwords, open tabs, cache, extensions — stays on your device. We do not receive it. Diagnostics, which you can turn off, do send us page addresses and the network log.

On the paid plans your catalog does sync so a second machine can pick it up: profiles, folders, workspaces, proxies, saved accounts, and app settings. Cookies you import onto an account card travel with that card; their values, like proxy passwords, are encrypted before they are stored. On the free plan nothing syncs at all.

Liminal runs natively on macOS (Apple Silicon) and Windows (ARM64).

Linux is not supported yet. Syncing your profiles, proxies, and accounts between machines is available on the paid plans; browser data does not travel with them.

Yes: HTTP, HTTPS and SOCKS5 proxies — residential, mobile or datacenter — and a WireGuard VPN per profile. A SOCKS4 proxy can be saved, but a profile does not open through it.

Paste a list or a file and every proxy is checked for IP and location; each profile gets one of its own, and its timezone and language follow it.

Unlimited profiles, free.
