Features

Everything you need.
Nothing you don't.

Performance Focused

Leaf Client includes built-in entity culling, particle distance limits, shadow optimization, and frustum-based rendering. These systems reduce GPU and CPU load without changing how the game looks. On mid-range hardware, players typically see 30-60% higher framerates compared to vanilla Minecraft. Every optimization is toggleable from the in-game Performance settings panel.

Mostly Open Source

The Leaf Client launcher and Fabric mod are publicly available on GitHub under an open license. You can read every line of code that runs on your machine, submit bug reports, or even contribute features. Security-sensitive systems like account authentication remain private to protect users — but the vast majority of the codebase is open for inspection.

0+ Built-in Mods

From ArmorHUD and Coordinates to Keystrokes, Minimap, and Waypoints — Leaf Client ships with every quality-of-life mod most players need. Each mod is configurable through a visual settings panel, and the HUD editor lets you drag and position elements anywhere on screen. No manual mod installation required.
