✦ Version 1.2.1 — Unlimited clients

Nightmare Zone,
on autopilot.

Runs as many OSRS clients as your machine can handle, drinks your absorptions, cycles your potions, and rock-cakes back to 1HP — all in one exe, all on hotkeys.

Windows 10 / 11 · RuneLite & official client · License key required
Features

Everything you need for AFK NMZ

Built for people who want to stack XP across many accounts without babysitting a single one.

Unlimited parallel clients

No 8-client cap. Attach to every RuneLite or vanilla window on your machine at once.

🧪

Auto absorptions

Watches your absorb bar and drinks the next dose the moment it dips — no missed sips.

🎯

1HP setup routine

One button (or F10) preps every client to 1HP with rock cake + locator orb, then hands off to the main loop.

🌡️

Potion cycling

Optional Super Combat or Super Ranging cycling on the right cadence for OSRS boost timers.

⌨️

Global hotkeys

F9 pause / continue, F10 1HP stop, F11 stop program. Works anywhere, even if the tool isn't focused.

📋

In-app logging

Every event routed to a log pane inside the app — no console flash, no cmd window.

Getting started

Up and running in three steps

From download to first XP tick in about five minutes.

Download & unzip

Grab the latest build, unzip anywhere, and double-click NMZ Tool.exe. No installer, no admin rights needed.

Paste your key

Enter the license key you were issued. The tool validates it against the server on every launch.

Pick your client & start

Select RuneLite or official client from the dropdown, hit Start Program, and the tool attaches to every open OSRS window.

FAQ

Common questions

Does it work with RuneLite plugins enabled?
Yes. The tool reads the client window by title match and drives it with real input events. Plugins like NMZ, Absorption Meter, etc. don't interfere — many users run with them on.
Do I need to keep the OSRS windows on top?
No. The tool sends input to background windows so you can keep doing other things on your PC while it runs.
How many clients can I actually run?
Limit is your hardware, not the tool. A modern 16GB / 8-core machine can comfortably drive 15+ RuneLite instances. Vanilla client uses less RAM per instance.
What if the tool doesn't detect my clients?
Check that your client window title starts with "RuneLite" or "Old School RuneScape". The tool matches by prefix, so RuneLite - Zoegreg, Old School RuneScape (Steam), etc. all work.
How do I stop and restart it mid-session?
Hit F11 (or the stop button). Every worker thread ends cleanly, and Start becomes available again immediately — no relaunch needed.
How do I get a key?
Contact the operator via the details on the download page. Keys can be issued as lifetime or timed (30d, 90d, custom).
Is it safe to run?
The tool runs entirely on your PC and only communicates outbound to validate your license. It does not read game memory or inject into the client — it uses standard window input APIs.
