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.
