Core Capabilities

Fingerprint browser capabilities built for multi-account operations

NexBrowser is a fingerprint browser built on a real Chromium core: every window is a fully independent fingerprint environment with its own cookies, cache, local storage and proxy. From isolation and fingerprint settings to window sync and the automation API, it brings multi-account management into one workspace.

  1. Give every account its own browser environment — each profile has its own cookies, cache, local storage and proxy configuration, so one profile's data stays independent of the others.

    • Manage all of your account profiles from one computer
    • One-click HTTP / HTTPS / SOCKS5 proxy binding
    • Profile groups, tags and bulk management
    Learn about profile isolation

  2. Built on the Chrome core, NexBrowser lets you configure 20+ fingerprint parameters individually — Canvas, WebGL, fonts, Audio, WebRTC, timezone and more — with built-in parameter templates covering Windows, macOS, Android and iOS.

    • 20+ fingerprint parameters that stay internally consistent
    • Network-layer parameters configured in sync with the profile
    • One-click generation / custom fingerprint profiles
    Learn about 20+ fingerprint parameters

  3. Operate one master window and every child window mirrors clicks, typing and scrolling in milliseconds. Plus a free Local API (Selenium / Puppeteer / Playwright) and no-code RPA to hand repetitive work to machines.

    • Synced actions are dispatched to every selected window in the same event loop tick, with a configurable interval between actions
    • Local API free and unlimited
    • No-code RPA workflows + AI Agent

FAQ

Frequently asked questions

Learn more about how NexBrowser works

How is each profile's data isolated?

NexBrowser gives every browser profile its own cookies, cache, local storage and login state, so no profile reads or overwrites another profile's data. Each profile also has its own configurable browser fingerprint parameters — over 20 of them, including Canvas, WebGL, WebRTC, fonts and timezone — and can be bound to a proxy of your own, so every profile runs on an independent configuration.

Which platforms does NexBrowser support?

NexBrowser is not tied to any particular platform — it works with any site where you need to keep several logins separate on one machine. Common use cases include accounts you manage on e-commerce platforms such as Amazon, eBay, Etsy, Shopee, Lazada and Shopify, and social platforms such as Facebook, TikTok, Instagram and X.

How does team collaboration ensure data security?

The owner account assigns member permissions by role. You can share access to a profile with a teammate without revealing the account password — they sign in and work directly in the pre-configured profile. Data is encrypted in transit and at rest, and permission changes and member activity are auditable in the console.

Do you offer a free trial?

Yes. Every new team gets a free plan with 1 member and 10 browser windows, and every feature is available on it — no credit card required. If you need more capacity, you can add windows at any time; see the Pricing page for details.

What proxy types does the proxy panel support?

NexBrowser's proxy panel supports mainstream proxy protocols including HTTP, HTTPS and SOCKS5. You can import and centrally manage proxies from any vendor, and assign a specific proxy to each individual profile.

How does window synchronization work?

Window synchronization lets you act in one master window while every child window mirrors the action in real time — mouse clicks, keyboard input and scrolling included. You can also set an interval between synced actions.
