Undetectable Browser (Undetectable.io) Proxy Setup Guide 2025

Undetectable.io offers easy proxy integration, but if you’re using it for the first time, it could be confusing. It isn’t about adding proxies, but the real challenge is with how to configure them for a task, which is where many get stuck.

It goes beyond: You might have questions about which proxy to use, how to assign it to profiles, how to make sure the connection stays consistent, or how to check if it’s even working.

We've answered all your questions through this guide. In case you’re new to Undetectable.io, we’ve also included a quick breakdown of what it is and its capabilities, so you won’t need to look elsewhere.

What is Undetectable.io?

Unlike conventional browsers, anti-detect browsers help hide your digital identity. Instead of just switching the IP address, they go beyond by adjusting browser fingerprinting. Plus, device information and other crucial system parameters are also taken care of to reduce the chances of tracking.

Undetectable.io is built on the same and is considered one of the best anti-detect browsers. It is often used by those who need to stay anonymous while managing multiple accounts, working across regions, or running tasks.

To better understand the Undetectable browser, it is important to be aware of its capabilities. This way, you can decide how to use it effectively and what features matter most when setting up your workflow.

Core Capabilities of Undetectable Browser

Undetectable.io is loaded with features. Here are the ones that make the biggest difference when you're using proxies or handling sensitive workflows:

Run multiple accounts from one place

With Undetectable.io, you can create and manage as many isolated browser profiles as you want, without needing separate devices or VPNs. This helps you log into multiple accounts without triggering platform filters or risking bans.

Customize how each profile looks on a website

Each profile has a fingerprint, which can be tracked when it is frequently used. With the Undetectable browser, you can create profiles with a unique browser fingerprint, meaning you appear as a completely different user with each session.

You get to customize the fingerprint, choose the desired UserAgent, screen resolution, number of CPU cores, installed fonts, WebRTC, and more.

Assign and reuse proxies easily

Undetectable.io comes with a built-in proxy manager. You can assign HTTP or SOCKS5 proxies to any profile and save them for later use. Plus, there is a built-in tool to test if your proxy is active, allowing you to test the connection before proceeding with task execution.

Create multiple profiles in one go

If you want to scale, the Undetectable browser has you covered. You can bulk-create profiles at once using templates, user-agent lists, or cookie files. With this feature, you can launch campaigns in different regions or test how various setups function within the same platform.

Warm up profiles using the Cookies Bot

Cookies Bot is one of the most relied-upon offerings of the Undetectable browser. It works best with a fresh profile, as it visits popular websites in a specific region on behalf of the user. As a result, an authentic browsing history is created, resulting in building trust with platforms that check behavioral patterns.

Sync your actions across profiles

Undetectable.io’s Synchronizer tool lets you perform the same actions in multiple profiles at once. This feature saves time and brings in consistency as repeated clicks or inputs across windows can be controlled from a single main session.

Automate what matters with API support

If you're into scripting or automation, Undetectable.io supports tools like Playwright, Puppeteer and Selenium. You can automate login tests, scraping flows, or profile setup routines by calling Chromium DevTools Protocol flags directly.

Why Proxies Are Essential for Undetectable.io?

After learning about the Undetectable browser and its features, you might wonder how it delivers. It isn’t just the features that complete the picture, but it's the proxies that back them up.

Anti-detect browsers like Undetectable.io take care of things like device details, screen size, WebGL configurations, etc. However, the proxies make it happen by offering necessary network-level separation.

As a result, each browser profile appears to be entirely coming from a different location, user, or environment. This is why proxies are essential. Without them, even the best configured fingerprint could be weakened by a reused IP address or a weak connection path.

Which Proxies Work Best with the Undetectable Browser?

Undetectable.io is suitable for performing various complex tasks, which is possible only with the right proxy. This is because working with the wrong proxy can significantly impact the session. Hence, here’s a breakdown to help you choose wisely:

Set Up Proxies on the Undetectable Browser with Ping Proxies

To get started, navigate to the Undetectable browser download page and choose the version compatible with your device—Windows or macOS (M Series and Intel). Once downloaded, proceed with the installation.

Upon installation, create an Undetectable account or log in if you already have one. After a successful sign-in, you can proceed with adding proxies by following the steps below.

Step 1: Generate Proxies with Ping Proxies

Each proxy provider has a unique proxy generation approach. With Ping Proxies, generating proxies is just a matter of clicks. There is no need for CLI or complex manual inputs—simply sign in and generate the proxy. We have made the entire process easier for you.

Generate Static Proxies

If you’ve purchased static proxies from us, click on the “Static Proxies” option under the “My Proxies” section on the left in the dashboard.

Your proxy list will be displayed with the IP address (hostname), port, username, and password. No generation is needed, just copy the credentials and you’re ready.

Generate Residential Proxies

Generating residential proxies involves a few additional steps. This is where you provide your proxy needs by selecting the options. Here are easy steps for it.

1. On the dashboard, navigate to the “My Proxies” section on the left and select the “Residential” option.

2. Choose between rotating or sticky proxies and select the protocol you want (HTTP or SOCKS5).

3. Set the location. You can choose the country, city, and ISP/ASN if needed, but broader targeting gives you a larger proxy pool.

4. Once you have selected all options, click on “Generate.” Your proxy list will appear in the format you selected.

Note: Always add the location to the username for the sticky proxies. Failing to do so routes you to the incorrect location.

Step 2: Create Profiles on Undetectable.io

Once you’ve generated the proxies, it’s time to create profiles inside Undetectable.io and link them with the right proxy settings. Here’s how to do it.

1. From the Undetectable browser dashboard, navigate to the “+ New Profile” button and click on it.

2. When you do so, the window expands, providing you with more options. First, assign the name to the profile, followed by the folder, group, and tags. Next, adjust the profile settings to your liking.

3. If you notice, you can find the person with the gear icon labelled “Main.” Click on it to access the proxy-related settings.

4. Set the proxy to “New Proxy” and select the proxy protocol (HTTP or SOCKS5)

5. Finally, enter the proxy details in the field provided. Make sure that you match the proxy structure supported by the Undetectable browser.

6. You can also set the IP Change Link and the proxy name, which are optional. Once everything is done, click on the “Create” button to successfully add proxies to Undetectable.io.

Use Proxy Manager To Add Proxies in Undetectable.io

You don’t have to create a profile every time you add a new proxy. Instead, you can use Undetectable.io’s Proxy Manager to save them and assign them to the profile of choice.

Proxy Manager helps manage all proxies in one place, from adding and testing to importing, editing, and deleting. Here is how to add proxies using it.

1. From the dashboard, navigate to the quick access options on the left. Find Proxy and click on it to open the Proxy Manager.

2. Now, click on the “+” button labelled “Add new Proxy” to open the “New proxy” pop-up.

3. In the pop-up window, fill in the Proxy name, Proxy type (HTTP or SOCKS5), Host, Port, Username, and Password.

Having trouble figuring them out from the proxy generated? Here’s a quick breakdown.

Example: socks5://user123_s_TMEK5I970J0IC4QJ:[email protected]:8864

All proxies generated follow the structure - (username_location:password@hostname:port number)

Not clear yet? Let us make it even easier for you.

• Proxy protocol: SOCKS5
• Hostname/Address: residential.pingproxies.com
• Port number: 8864
• Username & Location: user123_s_TMEK5I970J0IC4QJ
• Password: abc123

4. Once the respective fields are filled, click on the “Save Proxy” button to add proxies to the Undetectable browser.

Bulk Add Proxies in Undetectable.io

You can also add proxies in bulk using Undetectable.io's Proxy Manager. Follow the steps below to get started.

1. Click the Import button in the Proxy Manager. Unfortunately, the Import option isn’t available in the free version.

2. Doing so opens the Import proxy pop-up. Start by selecting your proxy type and input format. You can also set a start ID and name template if you want to auto-name each entry.

3. Paste your list of proxies in the field provided or upload a file. Once done, click on “Add Proxy” to add proxies in bulk to Undetectable.io.

Step 3: Test the Proxy Setup

After setting up a proxy, it’s always important to test it before running tasks. Inside Undetectable.io, you can do this in two ways:

• Use the Check button in the Proxy Manager when adding or editing a proxy.

• You can also test it directly while creating a new profile under the “Main” settings by clicking on "Check Proxy."

While handy, there’s a catch. What if your proxy doesn’t work even before you add it to Undetectable.io? To avoid that, try using the Ping Proxies Proxy Tester.

It’s a free tool that checks your proxies for uptime, speed, and regional performance. Just paste your proxy list, hit test, and instantly see which ones are good to go. You can even share or export the results if needed.

Fix Common Proxy Issues on the Undetectable Browser

While setting up or after successfully setting up proxies by following the steps, you might have come across a few issues. Here are the common ones and how to fix them:

• Proxy not connecting or failing the test: Always double-check the proxy format. Even making a small mistake can break the connection. Also, make sure the proxy is active and not expired or geo-blocked, which usually happens with non-reputable proxy providers.
• Selected the wrong proxy protocol: Undetectable.io supports both HTTP and SOCKS5, but you need to match the correct protocol with your proxy. Using SOCKS5 in an HTTP field (or vice versa) will lead to failed connections or browser errors.
• Session disconnects too quickly: If your session drops too frequently, it usually means a rotating proxy was used where a sticky or static one was needed. As explained before, we recommend using the right proxies based on your task. For logins or session-based activity, make sure to use a sticky residential or ISP proxy.
• Target site blocks or captchas: Even if the proxy is working, the IP might already be flagged by the target site. Try switching to a fresh residential or mobile proxy. Also, warm up the profile using Undetectable’s Cookies Bot to simulate normal user behavior.
• Wrong location or country mismatch: If your proxy string includes a location tag (like us, uk, etc.), make sure it matches the country you intend to appear from. A mismatch may lead to content not loading properly or being redirected.
• Proxy working, but profile behaves abnormally: This can happen if the browser fingerprint and the proxy location don’t align (e.g., an Indian IP with a US fingerprint). Try regenerating the profile with regional settings that match your proxy.
• Everything looks correct, but the connection still drops: Some providers require a session ID (SID) tag for sticky proxies. If your username string lacks this, the proxy might rotate unexpectedly. Check with your provider if SID formatting is needed.
