CloudLauncher Discord Download

A Minecraft launcher for Windows

Your packs,
on every PC you play on.

CloudLauncher keeps your modded instances on a server. Set a pack up once, then download it on the laptop, or give it to a friend with a link. Upload a change and the people you share with get it the next time they press Play.

Download for Windows What it does

Free Windows 10 and 11, 64-bit No admin prompt

The Instances page: a grid of instance cards, each with its cover, Minecraft version, loader, owner and a Play button, and folder chips above them.

Sync

Set it up once. Download it anywhere.

Publish an instance and its files live on the server. On another PC, sign in and press Download: same mods, same configs, same scripts. Your worlds and your keybinds stay on the PC they belong to.

Every instance says where it standsIn sync, an update waiting, changes of yours to upload, or not published at all. The two buttons that move files are Upload and Download.
Rules decide what travelsBy folder or by file, and the most specific rule wins. Anything on your private list never leaves this PC, whatever the rules say, and a download never overwrites it.
Nobody overwrites anybodyIf someone uploaded while you were working, the server turns your upload down instead of replacing their work, and the launcher shows who, when, and which files differ.

Sharing

Give a pack to a friend with a link.

Invite someone by username and the instance waits in their launcher until they accept or decline. Or copy a share link and paste it in a chat: it works until you revoke it, or until the expiry you gave it.

  • Pick what they can do: view, download, upload changes, or manage who else has it.
  • Share with a team instead of one person at a time. Teams have members, admins and an owner.
  • An invitation only ever adds. Redeeming a read-only link never takes away access someone already had.
  • The same server hosts your own mods, worlds, resource packs, shader packs, config sets, KubeJS scripts and data packs, shared the same way, each with its own versions and changelogs.
The Sharing page: instances you share and with whom, and invitations waiting for an answer.

Instances

Everything about one instance, on one page.

Play, update, export, open the folder. Logs sit next to crash reports, with find and a filter by level, and you can copy or save one for a bug report. Mods, resource packs, screenshots, worlds and files each have a tab.

An instance's own page: its name, Minecraft version and loader, the Play and Manage modpack buttons, Export, Open folder and Manage files, and tabs for mods, resources, screenshots, worlds and files.

A file manager per instance

Browse and drag files in, edit configs and scripts in place (encoding and line endings are kept as they were), see where the disk went, and diff the whole thing against another instance.

Downloads you can pause

A big modpack can be paused mid-file or stopped. Stopping takes the instance back to how it was before, and never touches files that were already there.

The right Java, and your own flags

The launcher picks the Java your Minecraft version wants and downloads it if needed. Memory and JVM arguments are per instance, and so is the Java if you want to choose.

Mods

Built for packs that got out of hand.

CurseForge and Modrinth in one browser, searched for the Minecraft version and loader of the instance you picked. Installing a mod brings its required dependencies. Then there's everything you need once a pack has a few hundred of them.

The dependency graph of a modpack: mods as boxes grouped by category, with arrows from each mod to the mods it needs.

The graph draws up to 3,000 mods and every line between them. Categories fold away, and a find box jumps to one mod.

A modpack planning board: sections of mod cards, note cards with task lists and a progress bar, a live group of every mod in the Magic category, and arrows between them.

Mod cards, live groups like "everything tagged Magic" that update themselves, notes with task lists or a progress bar, sections that carry their cards when you drag them, and arrows between any of it.

Update checks in bulk

The stores are asked about the whole pack in a few requests, even for 1,900 mods. Only the leftovers go one at a time, at a pace you set.

Every changelog in the jump

Updating a mod that's three versions behind shows all three changelogs, newest first. Right-click any version row to read that version's changelog.

Notes, categories, priorities

Tag mods with categories and priorities, leave a note on one, lock a version, mark it client-only. Conflicts are flagged, and every mod name links to its store page.

Servers

Every server from every instance, in one list.

Live status, players, MOTD and ping, checked in the background. Join straight from the launcher, and copy a server into another instance without opening the game.

  • An RCON console for the servers you run, with command history and buttons for the commands you actually type.
  • Or run one yourself: the launcher installs the matching NeoForge, Forge or Fabric server for an instance, starts and stops it, and shows its console.
  • Edit server.properties, ops, the whitelist and bans in a form, and see which of the pack's mods actually reach the server, so a client-only mod doesn't quietly break it.
The Servers page: servers from every instance with player counts and ping, and an RCON console for one of them.

Export

Hand the pack to people who use something else.

Export writes a CurseForge .zip or a Modrinth .mrpack. Mods from the stores go in as links, everything else is packed in, and disabled mods stay disabled.

  • Choose what goes in down to a single file: one mod's config left out, one world out of saves, or kubejs minus one script.
  • CurseForge exports carry modlist.html, the same file the CurseForge app writes.
  • Files marked private are shown as such and never leave your PC.
  • Import works the other way round: a .mrpack or a CurseForge .zip becomes an instance.
The export dialog: CurseForge or Modrinth format, and a file tree for choosing exactly which configs, scripts and worlds go into the pack.

Appearance

It looks like this page. Or like you want it to.

The launcher uses the design of the Slate Minecraft mods: warm near-black, one accent colour, pixel-stepped corners, hard two-pixel shadows, pixel headings (Pixeloid Sans by default) and pixel icons.

The Appearance settings change it as you go: the accent (thirteen presets or any colour), corners from square to four steps, motion speed and the pixel font (Pixeloid Sans, Monocraft or Pixelify Sans). Pixel headings, pixel text, pixel icons, shadows, page transitions and click sounds each switch on and off. There's a Vanilla skin in Minecraft's grey stone, and the Classic look if you'd rather have the old launcher back.

Settings, Appearance: Slate or Classic style, Dark or Vanilla skin, accent swatches, corner steps, motion speed and the pixel options.

And the rest

The parts that don't need a screenshot.

Worlds

Seed with a copy button, game mode, difficulty, version and size, read from the save itself. Back up and restore, duplicate, copy to another instance, import or export a .zip.

Packs stored once

Resource packs and shaders are kept once and linked into every instance that uses them: twenty instances with the same 400 MB pack cost 400 MB. When two packs replace the same files, the launcher says which one you actually see.

Config & scripts

Search inside every instance's config and KubeJS files at once, compare one file between two instances, and copy it into several; what it replaces is backed up first. KubeJS errors from the logs point at the script that caused them.

Storage that adds up

Where your disk went, by category and by instance. Linked files are counted once, and each instance shows what deleting it would actually give back.

Works when the server doesn't

If the server can't be reached you get the library you had, not an empty page, and a line that says whether the server refused or nothing answered at all.

Your own CurseForge key

Optional. Paste one in and CurseForge requests go straight from your PC with your key instead of queueing behind everyone else's on the server. It's stored encrypted for your Windows account.

Download CloudLauncher

Free, for Windows 10 and 11 (64-bit). It installs into your user profile, so there's no admin prompt, and it keeps itself up to date.

You'll need Minecraft: Java Edition on a Microsoft account, and a CloudLauncher account, which you make in the launcher with a username and password or with Google.
