Questions about Nether Client
Servers and fair play, your own mods, what the client sends, uninstalling, Mac and Bedrock. Missing an answer? Ask on Discord.
Getting started
Is Nether Client free?
Yes. Nether Client and Nether Launcher are free and show no ads.
Will Nether Client give me more FPS?
That is what it is built for. It bundles Sodium, Lithium, ImmediatelyFast, Entity Culling, More Culling, FerriteCore and Dynamic FPS, and adds performance patches we wrote ourselves, tuned for busy servers and text-heavy screens.
How much difference you see depends on your hardware. We will publish measured numbers on the performance page, with the hardware and the method named.
What do I need to run it?
A Minecraft: Java Edition account, Windows 10 or 11 (64-bit), macOS 12 or later or a 64-bit Linux distribution, and an internet connection for signing in and the first install. The launcher installs Java and the game for you.
Does it work on Mac?
Yes, as a preview. Nether Client runs on macOS 12 or later, on Apple silicon and Intel, from a .dmg on the download page, and on Windows 10 and 11 (64-bit) and Linux as an AppImage. The Mac build is not notarized by Apple yet, so macOS asks you to approve each new version once: the download page has the steps. The Mac launcher does not update itself; it shows a notice when a newer build exists.
Does it work with Bedrock Edition?
No. Nether Client is a client for Minecraft: Java Edition. Bedrock Edition, the version on consoles, phones and tablets, cannot run Java Edition mods.
Which Minecraft versions does it support?
Nether Client runs on Minecraft: Java Edition 26.3 today, and more versions are on the way. Nether Launcher can also run vanilla and Fabric instances of other game versions, without the Nether Client modules.
Why does Windows warn me when I run the installer?
The Windows installer is not code-signed yet, so Microsoft Defender SmartScreen shows "Windows protected your PC". Choose More info, then Run anyway.
To check that the file is ours first, compare its SHA-256 hash with the one on the download page.
How do I open the settings in game?
Press Right Shift to open the hub. Every module is listed there, searchable, with its settings beside it. The HUD editor, profiles and the profile gallery open from the hub.
Servers and fair play
Is Nether Client allowed on servers?
You can use it on any server. It has no features that give an unfair advantage, which is what server rules on modified clients are about.
Each server still sets its own rules. If a server lists the clients or mods it allows, follow that list.
Is it a cheat?
No. There is no reach, no x-ray, no auto-clicker and nothing that plays for you. The HUD shows what the game already tells you, such as your frame rate, coordinates and armour durability, in a form you lay out yourself.
Can a server see that I use Nether Client?
Yes. When you join a server, the client sends it a short hello with the client's version, the game version and the names of its modules. The hello contains nothing about your account.
Mods and compatibility
Does it work with my mods?
Nether Client is a Fabric mod, so it works alongside other Fabric mods made for the same game version. Add them in Nether Launcher from Modrinth, with their required dependencies, or drag your own .jar files onto an instance. The launcher asks before it installs a mod that says it is incompatible with one you have.
In the Nether Client instance, the managed performance mods stay as they are; mods you added yourself can be updated or uninstalled at any time.
Can I use shaders?
Yes. Iris Shaders is one of the optional extras, along with Sodium Extra, Reese's Sodium Options and Distant Horizons. They stay off until you switch them on.
How do updates work?
Nether Launcher checks for updates when it starts and every 15 minutes while it is open. It updates itself, the client and the managed mods, and checks every download against its SHA-256 hash, so you never reinstall anything by hand.
Privacy and accounts
What data does Nether Client send?
The client sends pseudonymous performance reports: frame-time and memory statistics with your hardware and settings, linked only to a random install id, never to your account or the servers you join. You can switch them off in the hub under Settings, Privacy, or in the launcher under Settings, Privacy; switching off also asks us to delete what was sent.
The profile gallery sends nothing until you open it. The launcher talks to Microsoft to sign you in, to Mojang and Fabric for game files, to Modrinth for mods and to our download server for updates. Crash reports are sent only when you choose to send one, unless you turn on sending them automatically.
The privacy page lists everything, with how to switch each part off.
Do you see my Microsoft password?
No. You sign in on Microsoft's own page in your browser, and the launcher keeps the sign-in token in your system's keychain. When the profile gallery signs you in, it uses Mojang's own session check: your Minecraft token goes to Mojang, never to us.
How do I uninstall Nether Client?
On Windows, open Settings, Apps, Installed apps, find "Nether Client" and choose Uninstall. Your instances and worlds stay in %APPDATA%\NetheriteLauncher until you delete that folder.
On Linux, delete the AppImage, the folder ~/.local/share/netherite-launcher (or $XDG_DATA_HOME/netherite-launcher) and the menu entry ~/.local/share/applications/netherite-launcher.desktop.
If you want the performance data deleted too, switch performance reports off before you uninstall: that sends the delete request.
