One browser. Every account.
Manage more accounts without paying more.
Give every account its own browser identity, then keep your work organized across devices and teammates.
Isolated identities
Each profile keeps its own browser identity, cookies, sessions, and storage so your accounts stay separate.
Cloud teamwork
Sync encrypted portable profiles, invite teammates, and work together, people and AI agents, through one shared workspace.
Detection-tested runtime
Passes the bot checks real platforms use.
AliasMode Chromium profiles open in CloakBrowser, a Chrome-based runtime patched at the source, so websites see a normal human-driven browser, not an automation tool. Here is how it compares on the public detection services that platforms use to screen visitors.
| Detection service | Standard automated browser | CloakBrowser | Notes |
|---|---|---|---|
| reCAPTCHA v3 | 0.1 (bot) | 0.9 (human) | Server-side verified |
| Cloudflare Turnstile (non-interactive) | FAIL | PASS | Auto-resolve |
| Cloudflare Turnstile (managed) | FAIL | PASS | Single click |
| ShieldSquare | BLOCKED | PASS | Production site |
| FingerprintJS bot detection | DETECTED | PASS | demo.fingerprint.com |
| BrowserScan bot detection | DETECTED | NORMAL (4/4) | browserscan.net |
| bot.incolumitas.com | 13 fails | PASS | Bot checks passed |
| deviceandbrowserinfo.com | 6 true flags | 0 true flags | isBot: false |
navigator.webdriver | true | false | Source-level patch |
navigator.plugins.length | 0 | 5 | Real plugin list |
window.chrome | undefined | object | Present like real Chrome |
UA string | HeadlessChrome | Chrome/150.0.0.0 | No headless leak |
CDP detection | Detected | Not detected | isAutomatedWithCDP: false |
TLS fingerprint | Mismatch | Identical to Chrome | ja3n/ja4/akamai match |
A standard automated browser is out-of-the-box Playwright or headless Chrome/Chromium, the default setup most automation scripts and bots use.
Point-in-time results from independent public test services; you can reproduce them yourself against a CloakBrowser profile. Detection vendors update their checks continuously, and no browser can guarantee a pass on every service forever.

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 profiles that pass the bot checks blocking stock automated browsers.
// start the profile
GET /api/v1/browser/start?user_id=PROFILE_ID

The antidetect browser you can fully audit.
Most antidetect browsers ship a closed engine. AliasMode ships its own: AliasMode Firefox, with every fingerprint patch public under MPL-2.0. The complete desktop app — dashboard, local runtime, Local API, and MCP server — is Apache-2.0. Chromium profiles run in CloakBrowser, a third-party engine included at no extra cost, and the optional Cloud sync is a hosted service.
