Undetectable Browser

👉 The server-side issues have been successfully resolved! Everything is back to normal. We apologize for the inconvenience.

⚠️ We’re currently experiencing server-side issues. We’ll do our best to resolve them as quickly as possible.

Undetectable 2.49.0 Update We have updated the browser engine to Chromium 151 — a fundamental component that determines the survival of all your accounts. Moving to the latest core version allows the digital fingerprint to blend in with the traffic of millions of real users without standing out to the anti-fraud systems of Facebook, Google, and crypto exchanges. In addition, the up-to-date engine eliminates rendering errors and ensures correct responses to new hidden verification scripts, providing maximum trust and technical stability for your sessions. ⚡Update to version 2.49.0 and always remain undetected! —————————————————— Website | Download The Browser | Documentation

Why Battery and Sensor APIs Can Expose Your Mobile Profiles When talking about fingerprint spoofing, you probably immediately think of User-Agent, WebRTC, Canvas, or fonts. But if you work with mobile profiles, anti-fraud systems look at much more than just these parameters. Two metrics that are often overlooked are the Battery API and Sensor API. These alone can expose you even if you are using the most trusted proxy. Let’s break down how it works. 🔋 Battery API The Battery API allows a website to determine the device’s battery level, charging status, and even the estimated time until the battery is fully discharged or fully charged. How this is used for detection: For example, you launch a mobile profile through an emulator or a poorly configured anti-detect browser. What does the target website see? Your “smartphone” stays at 100% battery for days and is constantly plugged into a power source. Real users do not behave like that. A real person’s battery drains, the phone gets plugged in at 15%, and the battery level changes even while the page is open. Static or unrealistic battery readings trigger anti-fraud systems and signal that they may be dealing with a bot. Important note: On Android (Chrome), websites can read this information automatically without asking for any permission. Safari on iOS, however, disabled the Battery API long ago. So if your profile pretends to be an iPhone but happily sends battery information to the website, the anti-fraud system immediately understands that it is fake and bans it. 📱 Sensor API The Sensor API gives websites access to the accelerometer, gyroscope, and ambient light sensor. This means that: When a real person holds a phone in their hands, the device is constantly making micro-movements. The tilt angle changes, the screen rotates, and fingers may block the light sensor. On Android, websites can also read these micro-changes by default when running over HTTPS. On iOS, user interaction is required, but protection systems still analyze behavioral logic. If your mobile profile sends zero values across the X, Y, and Z axes, or if these values remain completely static, the system understands that the device is lying on a table at best 😳 or does not physically exist at all, meaning it is an emulator. How Can You Avoid Getting Detected? Emulators and basic extensions stopped being enough a long time ago. Advanced anti-fraud systems can easily detect them precisely through these less obvious hardware-level metrics. To avoid losing accounts because of a “frozen” battery or missing gyroscope data, take a comprehensive approach to masking. For safer work with mobile and other profiles, use professional anti-detect browsers such as Undetectable. A professional anti-detect browser properly spoofs digital fingerprints and helps keep your accounts safe from protection algorithms. —————————————————— Website | Download The Browser | Documentation

🔤 🔤🔤🔤🔤🔤🔤 2️⃣⏺4️⃣8️⃣⏺0️⃣ Hi! We’ve rolled out the fresh 2.48.0 release. Today, we’re breaking down what has changed and how it will benefit your workflows. 📱 Chromium 150 The foundation of any secure work is an up-to-date browser base. The protection algorithms of top platforms instantly react when your browser version lags behind the one used by most real users around the world. With the current version 150 core, your digital fingerprint fully matches the latest web standards. 📶 Network emulation for Android profiles We’ve added the Network setting to the Emulation section specifically for mobile configurations. Now the browser sends a specific connection type to target websites through the navigator.connection.type parameter. This parameter does not exist on desktop, but for anti-fraud systems analyzing mobile traffic, it is a highly important indicator. By default, the program automatically assigns a logical random value to each new profile (cellular or wifi), saving your time when creating accounts in bulk. If you need surgical precision, the connection status can be set manually. This deep level of fingerprint refinement significantly increases profile survival rates on resources with the strictest anti-fraud systems. ⚙️ What about improvements? We’ve also made a couple of improvements to the stability and convenience of daily work: • Password leak notifications have been disabled: Built-in browser warnings about compromised passwords created unnecessary visual noise. When filling in hundreds of login forms in bulk, this was very distracting. • Cloud profile API has been fixed: Previously, when stopping a session programmatically, the server could return a success status even if the data had not been correctly sent to the cloud in time. This issue has been fixed. Your automation scripts now receive only 100% reliable statuses. ⚡️ Update to version 2.48.0 and stay undetected! —————————————————— Website | Download The Browser | Documentation

🔤🔤🔤 AI browser automation for $0: Integrating Undetectable with local LLMs AI automation is gradually taking over the market, but when scaling account farms, your inner cheapskate can instantly strangle you after seeing the API token bills. Although it is not just about money. Commercial AI tools have strict restrictions and censorship, and not every automation scenario will work with them. There is a free solution! Thanks to the MCP server built into the browser, you can connect your antidetect browser to any open local neural networks (Llama, Mistral, etc.), for example through the LM Studio app. This allows you to bypass censorship and fine-tune the neural network however you want. How the setup works LM Studio runs the language model directly on your PC. MCP server translates the neural network’s text commands into specific actions inside Undetectable profiles. 🔤🔤🔤 🔤🔤 🔤🔤🔤🔤🔤🔤🔤 (5 simple steps): - Download LM Studio from the official website and load the AI model you need. - Connect the MCP server: In LM Studio, open the Chat tab ➡️ Integrations panel ➡️ Install ➡️ Edit MCP Json. - Enter the data: Add the Undetectable MCP server settings, click Save, enable the server with the toggle, and grant the required permissions. - Restart the software: Close and reopen LM Studio and the Undetectable browser. - Start automation: Load the LLM in the Select model to load tab and send your first prompt in the chat! What can already be automated ✔️ Smart farming and warm-up: AI imitates real human behavior by naturally moving across websites and building up trusted cookies for anti-fraud systems. ✔️ Full-cycle SMM: Set up fully automated posting on Instagram. AI will log into the account, generate captions, upload media, and publish content while bypassing detection algorithms. ✔️ Ad account monitoring: The neural network will independently click through your profiles, collect data on remaining budgets, and provide a ready-made text summary or table. ✔️ Intelligent parsing: Collection and deep analysis of data from any resources in real time without writing custom parsers. *It is important to note that automation on a local neural network requires significant computing power from your PC. In other words, the more powerful your hardware is, the smarter the AI and the more complex the automation you will be able to deploy. 🤓 Read the detailed step-by-step guide on integrating Undetectable and LM Studio in our new article —————————————————— Website | Download The Browser | Documentation

🔥 Undetectable Hotfix We've rolled out a small but important update. Let's break down what's changed below. Control Over Cloud Profile Downloads When you are working with hundreds of profiles, constant background downloads can consume a lot of internet traffic and slow down your processes. Now, you can disable automatic downloading using the Auto-download cloud profiles checkbox in the settings. With auto-download disabled, profiles receive a Not sync status and are visually highlighted in the interface. You decide when to allocate resources to them: you can simply download the required account from the cloud, or click "sync and launch immediately." 🖤🖤🖤Note: You can only change profile settings after it has been downloaded from the cloud. New API Methods for Synchronization For those who automate routine tasks, we've added API methods to manage deferred downloads. Profiles waiting to be downloaded will return the status "status":"Need Sync". Two methods are available for management: /profile/sync/<id> — for targeted downloading of a specific profile. /profile/syncmany with the body ["<id1>", "<id2>",...] — for bulk downloading a specific pool of accounts from the cloud. Hide Video Devices Anti-fraud systems are getting more complex: some websites are starting to request webcam access (for example, to pass a video CAPTCHA) or checking for its presence for fingerprinting purposes. Now, the "Hide video devices" option is available in the profile settings. It conceals the presence of a camera from the target website; the system will be convinced that you simply don't have any video devices and won't be able to use them for detection.  Fix for iOS + Safari We removed the annoying system notification "Google API keys are missing", which previously could appear inside profiles using an iPhone footprint on Safari. Update your browser to enjoy the new features! —————————————————— Website | Download The Browser | Documentation

AI Detection: How Neural Networks Are Teaching Websites to Spot Bots A few years ago, anti-fraud systems were much simpler. Hide your real IP behind good proxies, spoof your User-Agent, warm up some cookies—and you were in. Today, the rules of the game have changed a bit. Cloudflare, Google, Facebook, and others are massively implementing AI models to catch multi-accounting. 😪 How AI Detects Bots and Multi-Accounts Behavioral biometrics. Neural networks analyze micro-timings: how fast you type, and whether your mouse moves in a perfect straight line or jitters like a living person's. Fast and perfectly precise actions are overly suspicious. Comparison with majority patterns. AI trains on millions of real user sessions. If your profile is perfectly configured but behaves differently from 99% of regular people on that site, the system will flag it as an anomaly. The "Software + Hardware" link. AI has learned to spot inconsistencies. For example, if you have a User-Agent from the latest iPhone, but your fonts and Canvas rendering indicate a Windows emulator, the neural network will issue an instant ban. 🙏 What Should You Do? Fighting AI is pointless—you need to deceive it by blending in with the "crowd." • Use deep fingerprint substitution. At Undetectable, we don't just randomize values (which is often exactly what gets caught by AI); we take real browser fingerprints from real devices. To the neural network, your profile looks like an ordinary person browsing from a regular home PC or smartphone. • Be "imperfect." Don't automate everything 100% without randomizing your pauses. If you use scripts for account warm-up, set up chaotic mouse movements, variable scrolling speeds, and pauses to "read" pages. If you're automating with AI, make sure to factor in pauses and human-like behavior in your prompt. • Maintain consistency. Your proxy, geolocation, time zone, browser language, and WebGL fingerprints must all follow a unified logic. Undetectable helps you synchronize this data in just a few clicks. Neural networks learn fast, so the golden rule today is: the quality of your profile and behavior is far more important than the quantity of your accounts. —————————————————— Website | Download The Browser | Documentation

📱 ChatGPT Runs Instagram: Codex + Undetectable Browser Automation! We've set up browser automation so that the AI itself opens the required profile, logs into the social network, creates a post, and publishes it. The coolest part is that this setup works even on the free version of Undetectable (you'll only need an OpenAI subscription). Let's break down how to set it all up yourself: Step 1️⃣: Prepare the base • Download the Undetectable anti-detect browser. • Install Node.js on your PC (it's required for the scripts to work properly). • Create a separate folder and put your ready-made images and post texts there. 🖤🖤🖤 The AI will need exact file paths. On Windows: hold Shift + right-click on the file ➔ "Copy as path" (it's better to remove the quotes when pasting). On macOS: right-click + hold Option ➔ "Copy path as pathname". Step 2️⃣: Launch Codex and connect the MCP Download the Codex desktop app and log in. Now you need to introduce the AI to the browser. To do this, send this prompt in a new Codex chat: "Connect the MCP server:" JSON

{
  "mcpServers": {
    "undetectable-local-api-ts": {
      "command": "npx",
      "args": ["-y", "undetectable-local-api-mcp-ts"],
      "env": {
        "UNDETECTABLE_BASE_URL": "http://127.0.0.1:25325",
        "UNDETECTABLE_TIMEOUT": "60"
      }
    }
  }
}

The AI will connect the server itself! After that, restart Codex and open Undetectable. Step 3️⃣: Automated posting After testing various algorithms, we found that asking the AI to look for buttons "with its eyes" works, but takes too long. Therefore, after some trial runs, we asked the neural network to analyze its own mistakes and write an optimized prompt for maximum speed itself! Create a new chat in Codex and copy this prompt into it, replacing the file paths with your own:

Start the Undetectable profile named Social UDT Wait 3 seconds after profile start. Connect to the profile’s returned websocket_link. Open Instagram directly at: Wait 3 seconds for the create upload page. If the Select from computer button is visible, click it and set this file in the chooser: [Path to image file] If a file input is already present, set the same file directly on input[type="file"]. Wait up to 45 seconds for Instagram to finish upload/navigation. Do not wait for Next buttons. The observed successful flow goes directly to: On the details page, fill the visible textarea: textarea[aria-label="Write a caption…"] with exactly: [Post text] Find the enabled button whose exact visible text is Share. Trigger the Share button directly with a full pointer/mouse/click event sequence on that button. Wait up to 90 seconds for Instagram to leave /create/details/ and return to Instagram home or another non-create page. Open: [Page URL] Wait 5 seconds. Take a screenshot confirming the newest grid item appears at the top-left of the profile grid.

For better results, we recommend running your own tests with the AI and, based on those, asking it to create a personalized prompt for you. 🔥 Try setting up your first auto-post today! 🖤🖤🖤🖤 For more details and visual screenshots, jump into the full article on our blog. —————————————————— Website | Download The Browser | Documentation

🔤 🖤🖤🖤🖤🖤🖤 2.47.0 In version 2.47.0, we have not only updated the browser core but also refined the mechanisms for automation and interaction with Google services. Let's break down exactly what has changed and how it will simplify your daily routine: 📱 Chromium 149 and Fresh Widevine True to our traditions, we are updating the core to the latest version, 149. Modern AI filters are trained in real time and know exactly which micro-delays during rendering correspond to the new versions of Chrome. With a fresh core, your profiles blend in seamlessly with billions of regular users. We have also updated the Widevine module. Anti-fraud systems frequently check DRM (content protection technology) components to assess the legitimacy of a device. A fresh Widevine confirms the integrity of the fingerprint and removes unnecessary suspicion from the account. 🤖 Improved Chrome Imitation We have changed the logic for generating the x-browser-validation header. This parameter is used by all Google services for a strict "humanity" check of the session. Now, our Chrome imitation has become even more precise. ⚙️ Automation For those who scale their account farms using scripts, we have rolled out some very useful upgrades: • Unlock method: The /profile/unlock/<profileID> method has been added to the API. Previously, if a script crashed or the network dropped, a profile could get stuck in a locked state, stopping the entire funnel. The new method forcefully returns the profile back to work. • Search in iframe: We improved how the native API interacts with elements inside frames (most commonly payment gateways and captchas). Your scripts will now find the necessary buttons faster and without errors. • AI automation: As a reminder, you can interact with websites without third-party libraries using our MCP server—just feed a prompt to the AI and initiate complex automation without the headache. 😜 Stable RDP Connection Resolved an issue where the program could close when reconnecting to the server via RDP. Remote management now works seamlessly and does not interrupt your multi-accounting processes. ⚡️ Update to version 2.47.0 right now and scale your projects with enhanced reliability! —————————————————— Website | Download The Browser | Documentation
