Antidetect Browser vs VPN vs Incognito Mode: What's the Difference?
People often lump three different tools together: incognito mode, a VPN and an antidetect browser. They all get described as "privacy tools," but they change completely different things. Picking the wrong one is the most common reason people feel disappointed with their setup. This guide explains what each tool actually does, with a side-by-side comparison, and when it makes sense to combine them.
The short answer
- Incognito mode keeps your browsing off your own device after the session ends.
- A VPN changes the network path and IP address your traffic appears to come from.
- An antidetect browser manages separate browser profiles, each with its own storage, settings and optionally its own proxy.
None of them makes you anonymous on its own.
Incognito mode: private from your own device
Google's Chrome Help is clear about the scope. When you close all Incognito windows, Chrome discards the site data and cookies from that session, and it does not keep a record of the sites you visited on your device. Chrome also states that Incognito does not change how data is collected by the websites you visit and the services they use, and that it does not make you invisible.
Mozilla describes its private browsing the same way: it keeps your local history private, but your internet provider, school or employer can still see where you have been, and websites still see your location through your IP address.
What incognito is good for: using a shared computer, signing in as a different user for a moment, checking a page without saved cookies or avoiding saved history for a one-off search.
What it does not do: hide your IP address, stop websites from collecting data, block your internet provider from seeing connections, or change what your browser reports about itself.
A VPN: a different network path
A virtual private network routes your device's traffic through a server run by the VPN provider. Websites see the VPN server's IP address instead of your home or office address, and the connection between you and the VPN server is encrypted. That helps on untrusted networks such as public Wi-Fi and lets you appear in another country.
Important limits to understand:
- You are trusting the VPN company with the traffic your internet provider used to see.
- Your browser fingerprint does not change. Your fonts, screen, graphics behavior and language settings are still reported exactly as before. Our explainer on browser fingerprinting covers what those signals are.
- Everyone on the same server shares an address, which some websites treat with suspicion.
- You are still logged in everywhere. Cookies and saved sessions are unaffected.
An antidetect browser: separate, configurable profiles
An antidetect browser (also written anti-detect) is a profile manager. Instead of one browser holding every account and session, you create separate profiles. Each profile has its own cookies and storage, its own settings for supported browser signals, and optionally its own proxy.
VertexStealth works this way on Windows: it launches the Chrome or Firefox you already have installed with a dedicated profile folder, so cookies and browser storage stay separate across managed profiles and from your everyday browser profile. You can set a proxy per profile, adjust supported signals such as user agent, language, timezone, screen and fonts, choose WebRTC behavior and use a built-in fingerprint check to see what the browser reports. The antidetect browser page goes deeper, and how it works walks through the three-step flow.
What it is good for: managing several client or campaign accounts without mixing sessions, testing a website from different configurations, regional research and QA work.
What it does not do: guarantee anonymity or stop a site from applying its own rules. Fingerprint configuration and profile separation are not a promise of invisibility.
Side-by-side comparison
| Incognito mode | VPN | Antidetect browser | |
|---|---|---|---|
| Main purpose | Leave no local history | Change network path and IP | Keep separate browser identities |
| Hides your IP from websites | No | Yes, behind the VPN server | Only if you set a proxy per profile |
| Hides activity from your internet provider | No | Partly, they see the VPN connection | Only if combined with a proxy or VPN |
| Changes browser-reported signals | No | No | Yes, for supported settings |
| Separates cookies and logins | Only for one session | No | Yes, per profile and persistent |
| Keeps profiles saved for later | No | Not applicable | Yes |
| Typical user | Anyone on a shared device | Anyone on public Wi-Fi or needing another location | Multi-account managers, testers, researchers |
Which one should you use?
- You just want no history on a shared computer: incognito mode is enough.
- You are on public Wi-Fi or need a different country's IP: use a VPN.
- You run several accounts or test environments and need them kept apart: use an antidetect browser with a multi-profile workflow.
- You need separate identities and a different IP for each: use an antidetect browser with a proxy configured per profile. Our guide to HTTP, HTTPS and SOCKS5 proxies explains how to choose.
You can also combine tools. A common setup is profiles with a proxy each, which makes a VPN unnecessary for that traffic. Avoid stacking tools you do not understand, since conflicting layers cause connection problems.
Using these tools responsibly
Separate profiles are widely used for legitimate work: QA, marketing agencies, research and development. Many platforms restrict running multiple accounts or automating actions. Check the terms of every service you use and the laws that apply to you. Our use cases page describes the workflows VertexStealth is built for.
Frequently asked questions
Is an antidetect browser the same as a VPN?
No. A VPN changes your network path and IP address. An antidetect browser manages separate browser profiles and settings. They can be used together, but they solve different problems.
Does incognito mode hide my IP address?
No. Websites still see your IP address in incognito mode, and your internet provider can still see your connections.
Do I need a proxy with an antidetect browser?
Not always. A proxy matters when each profile should appear on a different IP address. For simple isolation of cookies and settings you can start without one.
Is it legal to use an antidetect browser?
Browser profile managers are legal software in most countries. What matters is how you use them. Follow the laws and platform terms that apply to you. This is general information, not legal advice.
