Discover

Mods that work with your world, and only those

Search Modrinth and CurseForge without leaving the launcher. Pick the world you're installing into, and Cubby hides everything that wouldn't run on it.

No more grabbing the wrong version and finding out when the game refuses to start.

One click

Install a mod, get everything it needs

Every mod has a real page: what it adds, pictures, versions, changelog. Before you press Install, Cubby tells you it'll work with your world and which other mods come along with it.

Your mods

Switch a mod off instead of deleting it

Something broke after an update? Turn the mod off, play, turn it back on. Nothing gets deleted.

Updates show up on their own, and one button applies them all.

When it crashes

A crash comes with a way out

Instead of a wall of red text, Cubby reads the log and tells you what went wrong in plain words. Here, a mod made for Minecraft 1.21 in a 26.3 world. Then it lists what you can do about it, best fix first.

Repairing a world downloads the game files again and keeps your builds, your mods and your settings.

New world

Any version, any modpack, your own little picture

The latest release, a snapshot or 1.8.9 for old-school PvP. Fabric, Quilt, Forge or NeoForge. Modpacks from Modrinth, CurseForge, FTB, ATLauncher and Technic.

Then give it an emblem and a colour, or your own image, so you spot it at a glance.

While you play

Keep an eye on the game without leaving it

While the game runs, Cubby shows how long you've been playing, the game log as it happens, and the screenshots you take, the moment you take them.

Playing on a server? You see if it's up and how many people are on it.

Screenshots

Every screenshot, from every world

Press F2 in game, and that's it. Cubby gathers your screenshots from all your worlds, sorted by day, ready to copy and send to your friends.

And more

The little things that save your evening

Java, sorted

Cubby picks the right Java for each version and downloads it if you don't have it.
