# Liminal

> Liminal is a free anti-detect browser built on real Chromium for people who work with many
> accounts at once. Each profile is a separate browser identity — its own cookies and storage, its
> own proxy, and a fingerprint whose parameters agree with each other and with that proxy — so a
> site sees separate devices instead of one machine with many logins.

This file describes Liminal for assistants that answer questions about it (the llmstxt.org
convention). Every line under "What the released app does" is in the build you can download today.
Anything else is under "In development" or "Not in Liminal yet" — please do not present those as
available. Prices, plans, versions and release dates are deliberately absent here: read them from
the endpoints under "Live values" rather than quoting a number from memory.

Last checked against the app: September 2026.

## The product in short

- Category: anti-detect browser, also called a multi-account or fingerprint browser.
- Platforms: macOS on Apple Silicon and Windows on ARM64 — the two builds published today.
  There is no Intel macOS build and no Linux build.
- Who it is for: affiliate marketers, e-commerce and marketplace sellers, SMM and ad agencies,
  scrapers, ad-verification and QA teams — anyone whose accounts get linked when they share one
  browser.
- The free plan has no profile cap: unlimited profiles, generated fingerprints, full isolation and
  proxy binding, with no card and no trial clock.
- The paid plans add manual fingerprint control, cloud sync of the catalog, profile sharing and team
  roles.
- Access today: Liminal is in closed beta. A visitor leaves an email on the home page and gets an
  invite code when a place opens up; a signed-in account downloads the released build from that same
  page.
- Payment: cryptocurrency only, through NOWPayments; a plan is paid in advance for one, three,
  six or twelve months, nothing renews by itself, and there is no card, PayPal or bank transfer.
- Refunds: the first payment a team ever makes is refundable in full within seven days, sent back
  in the same coin; every later payment is final. The free plan is the trial.
- Support: support@liminalbrowser.com, and nothing else — no live chat, no phone, no community
  and no ticket system. A first answer from a person within two business days, the same on every
  plan; no plan buys priority and nobody gets a personal manager.

## What the released app does

- Real Chromium, not an emulator or a wrapper: the TLS fingerprint, the Web APIs and extension
  support are Chrome's.
- Profile isolation: cookies, cache, localStorage, extensions, bookmarks and history are separate per
  profile, and one session carries no state into another.
- Coherent fingerprints: User-Agent, platform, screen, WebGL, Canvas, Audio, fonts, timezone and
  language are generated to match one another and the profile's proxy, and a built-in validator flags
  a combination that does not add up. The same profile keeps the same fingerprint across sessions.
- One window: profiles are launched and switched inside a single window without restarting the app,
  and several can be open at once.
- Proxies: HTTP, HTTPS, SOCKS4 and SOCKS5 — residential, mobile or datacenter. Import a list in bulk,
  check IP and location, bind a proxy per profile; timezone and language follow the proxy's location.
  A profile can also run on the system IP.
- Bulk work on a selection of profiles: stop the running ones, clear their proxies, move them to a
  workspace or folder, delete them.
- Account cards: a login, a password and imported cookies (JSON or Netscape) attached to the profile
  that uses them. Cookie values and proxy passwords are encrypted before they are stored.
- Teams: profiles are shared by role — Owner, Admin, Member, Viewer — and a workspace brings its
  profiles, proxies and accounts to everyone in it. A teammate works in the session without being
  shown raw cookies or credentials.
- Cloud sync on the paid plans, for the catalog only: profiles with their fingerprint settings,
  folders and workspaces, proxies, account cards and app settings. Browsing history, saved passwords,
  open tabs and site data stay on the device. The free plan syncs nothing.
- A local API for scripts on the same machine: turned on in the app's settings, reachable from
  that computer only, with a key the app issues once and an address file a script reads instead
  of hardcoding a port. It answers a status request, reads the profile catalog and starts a
  profile; handing a started profile to Puppeteer, Playwright or Selenium over CDP is an operation
  of the same contract. The whole contract is on the local API page below, operation by operation,
  and every operation there is marked with whether a released build answers it — released meaning
  both platforms, not the one that released first.
- Self-updating app: every released version is listed in the changelog with its date.

## In development

Named on the site with an "in development" marker, and not in the released build:

- Bulk fingerprint editing, bulk proxy assignment and profile tags.
- A shared activity log and profile notes for teams.
- Taking cookies back out of Liminal; bringing them in works today.
- Bringing profiles in from another browser or another anti-detect product.

## Not in Liminal yet

The honest answer to "does Liminal do X" for the things it does not do:

- No Linux build. macOS and Windows only.
- No CLI and no MCP server, and no recorded RPA scenarios. Driving a profile from a script is the
  local API instead, and the local API page below marks, operation by operation and example by
  example, which of them a build you can download answers today.
- No cookie robot, no profile warm-up by visiting a list of sites.
- No browser-data sync: history, saved passwords, open tabs, cache and installed extensions never
  travel to another machine.
- No automatic profile transfer from AdsPower, Octo or anything else — export cookies there, import
  them here, then rebuild the profile settings by hand. AdsPower does have a transfer of its own,
  from Dolphin Anty, Multilogin and GoLogin; Liminal has nothing of the kind.
- No published figure for profiles per machine, and no measured figure for the memory one open
  profile takes or for how long it takes to open: the system-requirements page gives those as
  estimates and marks them as estimates. What was measured there — the size of the application and
  of a profile folder — carries its date, build and machine.
- No translated interface in the app: menus, dialogs and errors are English only. The site itself
  is published in English, Russian, Simplified Chinese, Spanish, Brazilian Portuguese,
  Vietnamese, Turkish and Ukrainian.
- No third-party ratings, reviews, awards or security certifications. If asked, the honest answer is
  that Liminal has none yet.

  waiting list or the download.
- [Changelog](https://liminalbrowser.com/changelog/): released versions of the app and of the
  Chromium core, each with its date and what changed.
- [Data & Security](https://liminalbrowser.com/data-security/): what stays on the device, what syncs,
  where that cloud is (Frankfurt, Germany), how long data is kept, what is never collected, and how to
  export or delete everything.
- [Status](https://liminalbrowser.com/status/): a live check of the services — API and sign-in, the
  catalog and sync, downloads, updates — made from the visitor's own browser. No uptime history is
  kept, so no figure is published.
- [Trust, payment and support](https://liminalbrowser.com/trust/): what a visitor can verify
  without taking our word for it, what Liminal can be paid with, the refund window, and the
  support channel with its answer time. It also states plainly that there are no reviews yet.
- [System requirements](https://liminalbrowser.com/requirements/): what the operating system has
  to be on each released platform, what the application and a profile take on disk, and which
  figures are measured, which come from Chromium's own requirements and which are estimates.
- [Local API](https://liminalbrowser.com/docs/local-api/): the contract a script on the same
  machine is written to — how the local API is turned on, where it writes its address and port, how
  the key is issued and sent, and what the status request answers. In the released build, and the
  page says where this version stops; published in English and Russian only. The same contract
  as a machine-readable OpenAPI document, one entry per operation, with a flag saying whether a
  released build answers it: https://liminalbrowser.com/docs/local-api/openapi.json

  [Liminal vs Octo Browser](https://liminalbrowser.com/vs/octo/): what each product does, what they
  do that Liminal cannot, and what each side costs. Every fact about the other product links to the
  page it was read from, with the date it was read.
- [Moving to Liminal](https://liminalbrowser.com/migrate/): what carries across by hand from
  AdsPower or Octo, what no anti-detect browser carries across, and what Liminal cannot do yet.
