Set up your first profiles in 5 minutes

2026-10-25

Install Nullprint on a Mac, sign up, add a US and a Japan proxy, create two profiles, run a check-up, then open Amazon in each: two separate browsers, each looking like a local visitor.

The steps in writing

1. Download and install — Download Nullprint from nullprint.ai for Windows or Mac (Apple silicon or Intel). On a Mac, drag Nullprint into Applications and open it from there.
2. Sign up — Click Sign up, enter your email and a password, then type the 6-digit code we email you. New accounts start a free 7-day Team plan trial.
3. Let the kernel download — The first time you sign in, Nullprint downloads its own Chrome kernel. It takes a minute or two and only happens once.
4. Add proxies and check them — Open Proxies, click “+ Paste proxies”, paste one proxy per line (for example host:port:user:pass) and click Add. Then click “Check all”: green “Working” means the proxy is good.
5. Create a profile — Open Profiles and click “+ New profile”. Give it a name you will recognize, like the store or account it is for. Leave Kernel and Chrome version as they are.
6. Choose its proxy — On the Proxy tab, pick “From proxy pool” and choose a proxy. Time zone and language follow the proxy's location automatically. Click “Create & lock fingerprint”.
7. Run a check-up — Select the profile and click Check-up. “Consistent” means the IP, time zone, language and fingerprint all agree.
8. Launch — Click Launch. A separate browser opens with its own fingerprint, IP and cookies. Use it like normal Chrome.
