Each profile carries its own timezone, language and hardware fingerprint.

Unlimited accounts. One device.

Every account gets its own browser identity.

Run as many accounts as your work needs from one computer, and keep each one apart from the others.

Unlimited profiles

Create a separate profile for every account, client, brand, or project. There are no profile limits and no fees.

A proxy per profile

Give each profile its own proxy. Proxy Tools check proxies in bulk and apply them to a folder or to selected profiles.

Antidetect browser benchmark · October 2026

The top score in our test of 12 antidetect browsers.

Open from engine to app

The antidetect browser you can fully audit.

Most antidetect browsers ship a closed engine. AliasMode ships two of its own. AliasMode Firefox has every fingerprint patch public under MPL-2.0. AliasMode Chromium is our own open-source Chromium 155 engine, and new Chrome profiles use it. The complete desktop app — dashboard, local runtime, Local API, and MCP server — is Apache-2.0. Chrome 146 profiles can still run in CloakBrowser, a third-party engine included at no extra cost on Windows, and the optional Cloud sync is a hosted service.

Local mode

Want to work without an account?

Use AliasMode Local. No account, no Cloud traffic: your profiles, cookies, and fingerprints stay on your computer.

Browser automation API

Automate profiles with the tools you already use.

Open profiles through the AliasMode Local API (AdsPower-compatible), attach the Playwright CDP endpoint, or hand the whole browser to an agent through the built-in MCP server — local stdio or Remote MCP with OAuth.

  • Start and stop browser profiles through HTTP.
  • Check profile and service status programmatically.
  • Connect Playwright directly to the running browser over CDP.
  • Expose profiles to Claude, ChatGPT, Codex, or any MCP client.
  • Run AI browser agents on persistent profiles, each with its own identity.
automation.js
// start the profile
GET /api/v1/browser/start?user_id=PROFILE_ID

// attach to what is already running
const browser = await chromium.connectOverCDP(
  res.data.ws.puppeteer
)

For teams

Bring the whole team, at no cost.

Share profiles between people and devices in Cloud, or keep every profile on one computer in Local mode. Both are free, with no seat or profile fees.

  • Workspace roles

    Each Cloud account has one workspace with owner and member roles. Invite teammates and hand profiles over between people.

  • Device revocation

    Revoke a workspace device when access ends. Deleted profiles go to Trash first, so they can be restored.

  • Encrypted profile sync

    Cloud syncs encrypted portable profiles, rejects stale uploads, and warns about concurrent opens.

  • Local mode

    No account and no AliasMode Cloud traffic. Profiles, cookies, and fingerprints stay on the computer.

  • Automation and AI agents

    AdsPower-compatible Local API, Playwright over CDP, and an MCP server for AI agents.

  • Open source on every desktop

    Windows, Mac (Apple Silicon and Intel), and Linux. The app is Apache-2.0, AliasMode Firefox is MPL-2.0, and AliasMode Chromium is GPL-3.0.
