RushRush Network Technology Ltd

A team that does one thing: take the fear out of multi-account operations

Q: Can you issue invoices or sign a contract?

Yes. Email support@nexbrowser.net with your team details and requirements, and we will provide company registration information, a contract template and invoicing documents.

Linked accounts, store re-verification, an ex-employee walking away with passwords, hundreds of identical clicks every day - that is what cross-border teams really pay. NexBrowser exists to fix those problems at the browser-core level: isolated environments, shared access without passwords, and automation for the repetitive parts.

About RushRush Network Technology Ltd

NexBrowser is built and operated by RushRush Network Technology Ltd. The team comes from browser-engine, proxy-network and cross-border e-commerce backgrounds. The product started as a fix for our own problem: dozens of stores on one machine, and accounts getting linked one after another.

We focus on kernel-level browser environment isolation. Every profile gets its own cookies, cache, local storage, 20+ fingerprint parameters and proxy configuration, so nothing leaks between profiles. Window sync, no-code RPA, a free Local API and an AI Agent hand the repetitive work to machines, while role-based access hands each account to the right person on your team.

Our goal is simple: make multi-account operations organized and easy to share across a team. For company registration details, contracts, invoicing or other compliance documents, contact us at [email protected] and we will provide them.

Core values

Three things we never compromise on

At NexBrowser we're not just shipping software - we're building tools teams can rely on for years.

Security and control

Audited code, data encrypted in transit and at rest, role-based permissions, password-free sharing and a full audit trail of who did what in which profile.

Speed and stability

From startup time and page loading to API latency and window-sync delay, every optimization exists so you wait one second less and click one time fewer.

Users first

We keep listening to what cross-border teams actually need. Isolation, collaboration or automation - every update comes from feedback of people running accounts every day.

FAQ

Frequently asked questions about NexBrowser

Who develops NexBrowser?

NexBrowser is developed and operated by RushRush Network Technology Ltd, the same entity named in the code-signing certificate of the Windows installer. You can verify the publisher in the installer’s digital signature.

Can you issue invoices or sign a contract?

Yes. Email [email protected] with your team details and requirements, and we will provide company registration information, a contract template and invoicing documents.

Where is my account data stored, and can teammates see passwords?

Profile data is encrypted and synced to the cloud. Teammates enter pre-configured profiles through password-free sharing, so they never need or see account passwords, and the owner can revoke access by role at any time.

How do I reach support?

Telegram support and the on-site chat respond in real time during working hours; emails to [email protected] are usually answered within one business day.
