Managing multiple accounts online without being detected by systems is often an extremely difficult task. Many platforms can obtain your browser fingerprint, IP information, and more device details through various means to detect whether you hold multiple accounts. In most cases, we can only solve this problem with anti-detection browsers, but anti-detection browsers are not cheap, or they adopt a subscription system. These expenses have a relatively high threshold for beginners or small teams.

Now we have good news for everyone. In 2025, there are still some reliable, trialable, or free anti-detection browsers available for us to use. In this article, we have compiled the top 5 anti-detection browsers worth trying to help you manage multiple accounts safely and stably.

What is an anti-detection browser?

An anti-detection browser is a professional type of browser whose main function is to hide your digital fingerprint (such as Cookies, browser type, IP address, computer parameters, and other information).

Platforms like Facebook, TikTok, and Amazon will all use browser fingerprints to detect if multiple accounts are being used. If detected, these accounts will be linked, leading to account restrictions or bans. Using an anti-detection browser can reduce the probability of these things happening.

Which groups of people are anti-detection browsers generally suitable for?

1. Cross-border e-commerce sellers

Need to manage multiple e-commerce stores (such as Amazon, eBay, Shopee, Etsy).

Need to avoid system association between different stores.

Example: A seller operates 5 brand stores and needs to ensure that each store appears to be independently operated.

2. Overseas advertising buyers (Media Buyers)

Operate multiple advertising accounts simultaneously (Facebook Ads, TikTok Ads, Google Ads).

Isolate each advertising account to avoid being banned due to logging in on the same device.

Example: A team controls 20 Facebook BMs and needs to simulate 20 different devices respectively without switching back and forth.

3. Affiliate marketers

Promoting affiliate products requires registering multiple traffic source accounts or testing different offers.

Prevent the platform from discovering that they are the same promoter.

4. Marketing teams/SEO teams

Need to test search results and advertising pages in different regions.

Simulate users from different countries visiting websites for SEO or competitor analysis.

Example: Use an anti-detection browser to simulate a US IP or IPs from other countries to check Google rankings.

5. Managers of multiple social media accounts

Operate multiple Instagram, Twitter, YouTube, and LinkedIn accounts simultaneously.

Avoid social platforms from determining that accounts are being (massively cultivated).

6. Data collection/testing personnel

Need to simulate multiple user environments during QA testing, web crawling, and automated operations.

For example, testing differences in the same web page on different devices.
