What's inside

Everything you need to play. Nothing you don’t.

Mods in a click

Create Fabric, Quilt, NeoForge or Forge instances, search Modrinth and install mods with their dependencies, or a whole modpack in one click. Each instance keeps its own version, mods, worlds and Java settings.

Every release, the right Java

Pick any Minecraft release (or a snapshot) and press Play. Arctic downloads the game and the exact Java it needs.

Play together

Invite friends into your world with a code. No server, no port forwarding: a direct link, or an encrypted relay when that isn't possible.

Any skin, any cape, free

Pick a skin from your library or copy a player's by name, choose a cape or use your own image (animated ones too), and every Arctic player sees it, on any account. Preview it all on a 3D model, and change your real Minecraft skin from the same place.

Fast, and faster in game

Downloads run in parallel over dozens of connections, so a complete fresh install takes about 20 seconds on a fast connection and relaunching is instant. In game, one switch adds Sodium, Lithium, FerriteCore, ImmediatelyFast and EntityCulling for much higher FPS.

Skin gallery

Browse skins other players shared, search by name or creator, wear one in a click, and share your own.

Every account, side by side

Sign in with Microsoft in your browser or with a short code, or add offline accounts for singleplayer and LAN. Switch in one click.

Profiles for everyone at the desk

Fully separate profiles on one PC, each with its own accounts, settings, instances and worlds. Game files are shared, so switching never re-downloads anything.

Bring your worlds

Import worlds from the Minecraft Launcher, Prism Launcher, other instances or a .zip, back any world up in one click, and restore deleted ones from the trash. Moving over from another launcher takes a minute.

Logs you can read

Live game output as readable lines, plus the launcher's own log. Filter by warnings or errors, search, copy.

Tuned your way

RAM, resolution, Java and JVM arguments per instance, Discord status, and Aurora, Dark or Light themes over an animated arctic night.

Updates that verify themselves

Stable and beta channels. New versions are hash-checked, then swapped in place in seconds, so you're always on the latest without reinstalling.

Arctic Client

Vanilla, with everything you'd install a client for.

Restyled menus, a dozen HUD widgets, Zoom, Freelook and PvP tools, built into Minecraft by Arctic. On by default for 1.21.6 and newer, in Fabric and Quilt instances too, and one switch to turn it off.

  • Ping

Cross, dot or circle crosshairs with size, gap, thickness, color and outline, previewed live.

  • Everyone's Arctic skins and capes
  • Animated capes

Make it yours

Give every instance its own snowflake.

Six snowflake styles and any colour you like, the same picker the launcher uses for instance icons. Try it.

The little things

Details you'll notice.

The small touches that make it feel finished.

Portable mode
Drop a portable.txt next to the launcher and it keeps everything in a folder beside it. Perfect for a USB stick.
Several games at once
Run more than one instance side by side, see what's running, open its log or force close it.
Snapshots and old versions
Every release by default, plus snapshots and the old alphas and betas when you want them.
Favorite versions
Pin the versions you actually play to the top of the list.
World trash and backups
Deleted worlds go to a trash you can restore from, and any world backs up in one click.
SOCKS5 proxy
Route the launcher and the game through a proxy, with sign-in support and a test button.
One window, or the tray
Opening Arctic again brings back the window you have, never a second copy. On Windows it can wait in the system tray when you close it.
One-minute setup
The first launch walks you through theme, account, memory and your first instance. Run it again any time.
Quick actions by Play
Open the game folder or the last game log right next to the Play button.
Your window, your way
Resolution presets, fullscreen, and whether the launcher stays open or gets out of the way when the game starts.
Every language's text
Chinese, Japanese, Korean and other scripts render properly with your system's fonts.
Pretty, never in the way
The animated arctic night pauses while you play. Prefer calm? Turn off the background animation or the intro.

Command line

Prefer a terminal? arctic has you covered.

A headless companion to the launcher. Create instances, install mods, manage accounts and profiles, and start the game from a terminal, a script or a remote session.

Same data as the app
Accounts, instances, mods and downloads are shared, so nothing is fetched twice.
Works over SSH
Device-code sign-in and detached launches, no window needed.
Built for scripts
--json streams one event per line, with exit codes you can rely on.
One-click shortcuts
arctic open --launch 1.20.1 starts the launcher straight into a version.

Local by design

Your accounts stay on your PC.

No telemetry and no analytics. Sign-in tokens stay on your PC and only go to Microsoft and Mojang. Arctic’s looks service never sees your password or tokens: it checks who you are the way a Minecraft server does. Everything else sits in one folder you can open, back up or delete.

FAQ

Questions, answered.

Is it free?+

Yes. Arctic Launcher is free and open-source under the GPL-3.0-or-later license. No ads, no premium tier.

Do I need to install Java?+

No. The launcher downloads the exact Java runtime each Minecraft version expects, straight from Mojang, and keeps it in its own folder.

Is my Microsoft login safe?+

Sign-in happens on Microsoft's own page in your browser (or with a short code). The launcher never sees your password, and the tokens stay on your PC and only go to Microsoft, Xbox and Mojang. Arctic's looks service never receives them: it checks who you are the same way a Minecraft server does.

Can I play without a Microsoft account?+

Yes. Add an offline account for singleplayer and LAN, and it gets Arctic skins and capes like any other account. Online servers that check accounts still need a Microsoft account that owns Minecraft: Java Edition.

Mods?+

Yes. Create a Fabric, Quilt, NeoForge or Forge instance under Instances, then browse Modrinth for mods (dependencies included) or install a whole modpack in one click. You can also drop .jar files into the instance's mods folder.

How do skins and capes work?+

Pick any skin or cape in the Skins tab, even your own image, or browse the community gallery for skins other players shared. Every Arctic player sees your look in game through Arctic Client, including animated capes. You can also change your real Minecraft skin from there.

What is Arctic Client?+

Arctic's built-in client: restyled menus (Arctic, Aurora or Classic), a dozen HUD widgets that snap into place, Zoom, Freelook, Fullbright, Toggle Sprint and Sneak, a crosshair editor, a smooth font and everyone's Arctic looks. Press Right Shift in game for its menu. It's on by default for Minecraft 1.21.6 and newer, works in Fabric and Quilt instances, and you can turn it off per instance.

Will it run faster than the official launcher?+

The game itself usually does: the Performance switch adds Sodium, Lithium, FerriteCore, ImmediatelyFast and EntityCulling to Vanilla, fetched from Modrinth for your version. It's on by default wherever Fabric supports the version, and you can turn it off.

Do my friends need Arctic to play together?+

Yes: both of you need Arctic Launcher, the same Minecraft version and the same mods. Open your world to LAN, share the code, and Arctic connects you directly, or through an encrypted relay when a direct link isn't possible.

Windows says it protected my PC. Why?+

SmartScreen warns about new executables that haven't built up a download reputation yet. Click “More info” → “Run anyway”, or check the SHA-256 on the download page first.

Can I use it from the command line?+

Yes. The arctic CLI shares the launcher's data: launch versions and instances, install mods, manage accounts and profiles, with JSON output for scripts. See the command line guide at docs.arcticlauncher.com.

Which systems does it support?+

Windows and Linux (x64). Linux needs an X11 or Wayland desktop with OpenGL. macOS isn't supported yet.

Where does it keep my files?+

Windows: %LOCALAPPDATA%\ArcticLauncher. Linux: ~/.local/share/ArcticLauncher. Each profile has its own folder inside, and arctic paths prints them all. Drop a portable.txt next to the launcher and it uses a data folder beside it instead, handy for USB sticks.

Where can I get help?+

Join the Discord at arcticlauncher.com/discord: post in the support forum and attach your logs, and the bot checks them for known problems right away. Bugs can also go straight to GitHub issues.

Is this an official Minecraft launcher?+

No. It's an independent project, not affiliated with Mojang Studios or Microsoft. It downloads the game from Mojang's official servers.
