Antidetect browser for Windows
VertexStealth is an antidetect browser (also written anti-detect) for Windows. It runs separate Chrome and Firefox profiles, each with its own proxy and configurable fingerprint settings, so every profile presents its own browser environment instead of sharing yours.
What is an antidetect browser?
A website can read many details about the browser visiting it: the user agent, language, timezone, screen, fonts, graphics and WebRTC information, and more. Together these details form a browser fingerprint. An antidetect browser lets you choose them per profile and keeps each profile's cookies and storage apart, so separate sessions do not share an environment by accident.
"Antidetect" names the category. It does not mean invisible: websites use many signals and their own rules, and no tool can promise otherwise.
How does VertexStealth work as an antidetect browser?
VertexStealth is not a new browser engine. It launches the Chrome or Firefox you already have installed, with a dedicated profile folder and the settings you chose for that profile. You keep the real browser and its updates, while VertexStealth manages the profile, proxy and fingerprint settings around it.
- Chrome: started with its own data folder and launch settings, then configured through the browser's DevTools protocol.
- Firefox: started with a prepared profile and a bundled extension, and controlled through Firefox's Marionette interface.
- Isolation: each profile has its own cookies, local storage and cache, separate from your everyday browser.
Which browser signals can you configure?
| Setting | What you control |
|---|---|
| Navigator and language | User agent, platform, Client Hints and browser language, which can follow the proxy's country |
| Timezone and location | Timezone and geolocation, matched to the proxy IP or set by hand |
| Proxy | HTTP, HTTPS or SOCKS5 per profile, including authentication |
| WebRTC | Modes that control which IP addresses a page can see |
| Fonts, display and hardware | Font list, screen and window settings, CPU cores, memory and media devices |
| Rendering | Canvas, audio and WebGL details |
Availability and behavior depend on the browser and on the profile's configuration.
Antidetect browser vs a regular browser
| Feature | Regular browser profiles | Private window | VertexStealth |
|---|---|---|---|
| Separate cookies and storage | Yes | Until the window closes | Yes, per profile |
| Per-profile proxy | Not built in | Not built in | Yes |
| Configurable fingerprint signals | No | No | Yes |
| Built-in fingerprint check | No | No | Yes |
| Saved, reusable profiles | Yes | No | Yes |
How do I set up an antidetect profile?
- Create a profile. Pick Chrome or Firefox and choose a Windows or mobile preset, or randomize the supported settings.
- Set the environment. Add a proxy, let timezone, location and language follow it or set them by hand, and choose a WebRTC mode.
- Launch and check. Open the profile and run Fingerprint Check to see what the browser reports before you use it.
What VertexStealth does not do
- It does not guarantee anonymity, undetectability or protection from account restrictions.
- It is a Windows app only. There is no macOS, Linux, mobile or cloud version, and no team sharing of profiles.
- It is not meant for activity that breaks the law or the terms of the sites and platforms you use.

Frequently asked questions
What is an antidetect browser?
An antidetect browser (also written anti-detect) lets you choose the browser details a website can read, such as user agent, language, timezone and WebRTC behavior, separately for each profile, and keeps each profile's cookies and storage apart.
Is VertexStealth a separate browser?
No. VertexStealth launches the Chrome or Firefox you already have installed, with its own profile folder and per-profile settings, so you keep the real browser engine and its updates.
Does VertexStealth make me undetectable?
No. Sites use many signals and their own rules, so no tool can guarantee anonymity, undetectability or freedom from restrictions. VertexStealth helps you control and inspect your browser environment.
Which signals can I configure?
Per profile you can configure the user agent and platform, language, timezone and geolocation, proxy, WebRTC behavior, fonts, display and hardware values, and canvas, audio and WebGL details. Some settings differ between Chrome and Firefox.
How can I test a profile?
Use the built-in Fingerprint Check to see what the running browser reports. You can also open outside testers such as BrowserLeaks and iPhey from the app.
Does it run on macOS or Linux?
Not yet. VertexStealth is a Windows 10 and 11 desktop app.
Is it allowed to use an antidetect browser?
Browser profile and fingerprint tools are general-purpose software. How you use them is your responsibility: follow applicable laws and the terms of the sites and platforms you use.
