Every feature an isolated browser profile needs
Fingerprint, network, storage and team controls, built into a browser that works like Chrome.
Works like Chrome
Same speed, same extensions, same websites. Profiles stay on the latest Chrome version, because an outdated browser stands out.
Consistent fingerprints
User agent, client hints, screen, fonts, WebGL, canvas and audio come from one coherent device profile, and they match in every frame and worker.
Proxy per profile
HTTP, HTTPS and SOCKS5 per profile. Timezone, language and geolocation follow the proxy's exit IP, and WebRTC shows the proxy, not your network.
Isolated storage
Cookies, localStorage, IndexedDB, cache, service workers and permissions live in a separate store for each profile. Nothing crosses over.
Team workspaces
Share profiles with teammates, set roles and folder access, and hand a profile over without sharing passwords or exporting cookies.
Encrypted cloud sync
Profiles sync between machines on close, so a profile opened on another PC continues the same session.
Automation API
Start profiles from a local REST API and drive them with Puppeteer, Playwright or Selenium over the Chrome DevTools Protocol.
Bulk tools
Create profiles in bulk, import proxy lists and cookie files, tag and filter hundreds of profiles, and launch a whole folder at once.
A complete, coherent device for every profile
NexLogin changes values inside the browser engine, not with injected JavaScript, so there are no patched functions for a page to inspect.
| User agent and client hints | Full UA string, UA-CH brands, platform and version, consistent with each other and with the real browser version. |
| Hardware | CPU cores, device memory, screen size, colour depth and pixel ratio from a real device model. |
| WebGL and WebGPU | Vendor and renderer strings plus the matching parameters, extensions and limits of that GPU. |
| Canvas, audio and ClientRects | Stable, per-profile noise: the same profile gives the same hash every session. |
| Fonts | The font list the claimed operating system ships with. Fonts outside it are hidden. |
| Media devices and voices | Cameras, microphones, speakers and speech voices that fit the device. |
Your real IP stays out of the session
A proxy only protects you if every request uses it. NexLogin routes the whole profile through it and aligns the profile with the exit IP.
| Proxy per profile | HTTP, HTTPS and SOCKS5, with authentication. Bulk import from a list. |
| WebRTC | Shows the proxy's public IP and hides local network addresses, or turns WebRTC off per profile. |
| DNS | Name lookups go through the proxy, so your ISP's resolver never appears. |
| Timezone, language and location | Set automatically from the proxy's exit IP when the profile starts, or fixed by hand. |
| Proxy check | Test a proxy's exit IP, country and latency before you assign it. |
Profiles that never touch each other
Each profile has its own data directory. Nothing a site stores in one profile is visible from another.
| Separate storage | Cookies, localStorage, sessionStorage, IndexedDB, cache and service workers per profile. |
| Separate permissions | Notifications, location and camera choices are remembered per profile. |
| Extensions per profile | Install Chrome Web Store extensions in the profiles that need them. |
| Cookie import and export | Bring sessions in from JSON or Netscape cookie files, or export them for backup. |
Share profiles, not passwords
Workspaces let a team run accounts together while keeping control of who can do what.
| Workspaces and folders | Group profiles by client, platform or project. |
| Roles | Owner, admin, member and launch-only access, set per folder. |
| Hand-over | Give a teammate a logged-in profile; take it back in one click. |
| Cloud sync | Encrypted sync of profile data, so a profile continues on any PC. |
| Audit log | See who opened, edited or shared each profile (Business plan). |
A local API and standard CDP
Create and start profiles from code, then connect Puppeteer, Playwright or Selenium to the running browser.
- Create, update, start, stop and delete profiles
- Returns a DevTools WebSocket URL on start
- API keys per workspace member
# Start a profile from the command line
curl -X POST http://127.0.0.1:35000/v1/profiles/shop-us-01/start
# Response
{
"id": "shop-us-01",
"wsEndpoint": "ws://127.0.0.1:52117/devtools/browser/…"
