What is Catalyst

One app for all of it.

Catalyst is two things that work as one: a launcher that looks after Minecraft for you, and a client that makes the game itself better.

A launcher that sets things up

Profiles, memory, Java and mods - installed with everything they need, checked against your version, and kept up to date.

A client with 57 modules

FPS, CPS, coordinates, a minimap, zoom, waypoints, projectile prediction and more - one Right Shift away.

Cosmetics you can see

Wings and capes from the store, the battle pass and daily rewards - shown in 3D on this site.

Rewards and a community

Coins, codes and a daily calendar - and a site where players design the capes everyone votes on.

Catalyst Shaders

Scroll, and the shader comes on.

A real shader pack, built into the client: shadows from the sun, volumetric clouds, reflections, natural colours and fog - smoke in the Nether, a black hole in the End. Scroll down and the line moves from Minecraft as it comes to Catalyst Shaders, or drag it yourself.

The same sunrise with Catalyst Shaders: real shadows under every tree, sunlight through soft volumetric clouds and haze over the distance

The Overworld at sunrise - real shadows, clouds you could fly through, light through the haze.

The same place with Catalyst Shaders: grey-brown smoke fills the Nether, lit warm by the lava, the far walls fading into it

The same view with Catalyst Shaders: a black hole with a white-hot disk hangs between the pillars in a swirling grey vortex, the end stone lit bright under a near-black sky

Side by side

Same world. More to see.

Two shots of the same moment in the same world. Drag the line: Minecraft as it comes on the left, Catalyst on the right. The minimap is Xaero's Minimap by xaero96 - his mod, installed from the Mods page in one click.

The same moment with Catalyst: Catalyst Shaders puts soft clouds in the sky and the mountain and clouds reflected in clear water, the Stoneheart Gauntlet is on the hand, ping, CPS and playtime run down the left, with the frame rate under them, and Xaero's Minimap - xaero96's mod - sits in the corner
