Undetectable Browser

Proxies not working? Check these things before replacing them Your profile launches, but a website won’t load. Or your proxy passes the check, yet the platform you need is still unavailable. There can be several reasons, so avoid changing all your settings at once. 1️⃣ Check your connection details The address, port, username, password, and proxy type must match the details provided by your proxy service. Don’t choose HTTP or SOCKS5 at random: use the protocol and port your provider specified. If access is authenticated by IP, check your provider’s list of allowed addresses. Your external IP may have changed after switching networks or enabling a VPN. 2️⃣ Check whether the proxy is active In your provider’s dashboard, check the expiration date, remaining traffic, and connection limits. Then run Undetectable’s built-in proxy checker, available in the profile card, settings, and proxy manager. This lets you start troubleshooting directly in the browser. 3️⃣ Separate connection issues from website-specific issues If other pages load through the proxy but one platform doesn’t, that doesn’t necessarily mean the proxy has stopped working entirely. The cause could be restrictions imposed by the website or provider, or a temporary outage. A successful proxy check confirms the result of that particular test, but does not guarantee access to every service. 4️⃣ Consider the impact of your network and VPN A VPN doesn’t necessarily conflict with a proxy. However, it changes the connection route, and some networks restrict certain protocols. To troubleshoot, try connecting to the same proxy from another available network. Change one condition at a time — otherwise, it will be difficult to tell what affected the result. 🔤🔤🔤 Undetectable supports SOCKS5 proxies with UDP This allows WebRTC traffic to pass through a compatible proxy. QUIC support has also been added — this is the protocol used by HTTP/3. There’s an important detail: the proxy itself must support UDP. Enabling a browser setting alone is not enough. In the profile settings, under Main, you’ll find the Proxy with UDP support option. During a proxy check, UDP support is shown by a separate indicator: green if the check succeeds, red if support is not confirmed. Don’t enable this option for proxies without UDP support, as it may disrupt WebRTC. If regular pages load but QUIC doesn’t work, check your provider’s UDP support and any network restrictions separately. UDP support has been introduced in test mode, so your feedback on how it works is especially valuable to us. Still can’t find the cause? Contact Undetectable support. Include your browser version, proxy type, error message, and specify whether all websites fail to load or only one. ———————————————— Website | Download The Browser | Documentation

👛 More wallets and projects. Less busywork. Airdrops, retroactive airdrops, testnets, Web3 quests — every project comes with its own websites, extensions, and connections. The more you manage, the harder it gets to keep everything organized in one browser. Undetectable lets you give each wallet its own browser profile — with separate cookies, extensions, proxies, and a digital fingerprint. Unlimited local profiles are included on every paid plan. 🪂 Where does this help? • Airdrops and retroactive airdrops: save each project’s workspace and return to your activities without constantly switching wallets. • Testnets and new dApps: create separate profiles for test wallets and experimental extensions. • Rewards programs and Web3 quests: save task pages and track your progress while following each project’s participation rules. ⚙️ What makes the workflow easier? → A dedicated profile for every project Open the wallet you need alongside its settings and saved sessions. Names, folders, and tags help you find the right workspace and keep track of your dApp connections. → Separate browser fingerprints Different wallet addresses don’t automatically mean separate browser environments: websites can also consider your IP, cookies, and device parameters. Separate fingerprints and proxies in Undetectable help reduce shared browser signals across profiles. On-chain transactions remain public. → Local storage without per-profile fees Keep profiles on your computer without mandatory uploads to Undetectable’s cloud. Every paid plan lets you create as many local profiles as your projects need. → Bulk extension installation Add MetaMask, Rabby, Phantom, and other extensions to selected profiles through a single extension manager. → Automate repetitive tasks The synchronizer on Windows repeats actions such as opening pages and typing across multiple windows. The local API lets you manage profiles through scripts, while MCP lets you connect an AI agent to prepare workspaces and gather information. Start with one project: create a profile, install the extension you need, and save your workspace for the next session. 👉 Try Undetectable for free Subscribe to the channel for practical guides on setting up profiles, cutting repetitive work, and bringing automation into your projects.

🌐 Your IP changed. What about your browser? A proxy changes the IP address a website sees. But your cookies, browser settings, and digital fingerprint don’t automatically change with it. If you manage multiple projects or accounts in the same browser profile, switching proxies alone won’t separate their environments. Undetectable complements your proxies: a separate browser profile with its own cookies, fingerprint settings, and proxy connection for each task. Here’s how that helps your workflow ↓ → Separate your environments, not just your IPs Create individual profiles for ad accounts, stores, and client projects. Sessions and cookies stay separate, while browser fingerprint settings can be configured for each profile. → Manage your proxies in one place Add proxies individually or in bulk, check their connection status, and assign them to profiles. Bring your own proxies and manage them alongside your browser environments. → Scale without paying for each local profile Every paid plan includes unlimited local profiles, stored on your device. Your profile count won’t force you to buy a larger package. Adjust the number of browsers running simultaneously to suit your computer’s resources. → Set up multiple profiles at once Bulk profile creation, cookie imports, and extension installation help you prepare your environments without repeating the same steps manually. Use the synchronizer to perform identical actions across multiple browser windows. → Add automation as your workload grows The local API has no request limits and lets you create and launch profiles, assign proxies, and manage sessions from your scripts. Selenium, Playwright, and Puppeteer are supported. You can also connect an AI agent via MCP — for example, to create profiles and assign proxies from a list. Compatible local models running through LM Studio are an option too. Start with a task you already do: create a profile → connect your proxy → check the connection → open the website you need. The free plan includes 5 cloud profiles. Unlimited local profiles are available on paid plans. 👉 Try Undetectable Subscribe to the channel for practical guides on proxies, browser profiles, and automation you can use in your own projects.

⚙️ More automation. Fewer restrictions. A local API with no request limits, unlimited local profiles on every paid plan, and protection against automation detection — all in Undetectable. Writing scripts with Selenium, Playwright, or Puppeteer? Building AI agents? Here’s what the browser can bring to your projects ↓ Undetectable is an antidetect browser with a local API with no request limits and unlimited local profiles on every paid plan. Here’s what that means for your workflows: → Scale without paying for each local profile Create profiles, assign proxies, manage cookies, and start and stop sessions through the API. Your local profile count won’t force you to upgrade your plan. Adjust concurrency to suit your machine’s resources. → Protection against automation detection Our own ChromeDriver for Selenium, protection against DevTools Protocol detection, and suppression of the webdriver flag during automation. These mechanisms help make browser automation less detectable. → Control within web pages Built-in API methods for navigation, clicks, scrolling, and text entry that mimics human typing. Control the browser directly or connect your familiar Selenium, Playwright, and Puppeteer tools. → Settings for background workflows Focus emulation options for hidden windows and headless workflows — useful when multiple profiles run simultaneously and keeping every window in the foreground isn’t practical. Working with AI agents? Connect via MCP. Connect Undetectable to an AI client, including one running a compatible local model through LM Studio. For example, ask an agent to go through your ad accounts and compile a summary of remaining budgets. Running the model locally means you don’t pay for cloud LLM tokens. Start with one of your existing workflows: create a profile → launch the browser → run the task → save the result. 💻 Try for free 📖 API documentation Subscribe to the channel for automation guides and Undetectable updates you can put to work in your own projects. —————————————————— Website | Download The Browser | Documentation
