No JVM. Faster startup, lower memory. Built from scratch — not a Java mod.
Windows · macOS · Linux · Minecraft 1.8.9 (protocol 47) · Multiplayer only
Everything below is running right now. The list is short — we're being honest.
Microsoft account authentication via Device Code Flow. No offline-only accounts.
Connects to any vanilla-compatible 1.8.9 server. AES/CFB8 encryption + zlib compression.
No JVM. Rust + wgpu rendering, tokio networking. Faster boot, lower RAM than Java clients.
Tauri-based cross-platform launcher. Account management and version selection.
Drag-to-place HUD elements. Positions saved per profile.
Standard 1.8.9 resource packs work. Apply and manage from the in-game menu.
14 of ~150 planned mods implemented.
These are on the roadmap. None of the items below work yet. We're showing them so you know where the project is heading.
Most 1.8 custom clients are Java mods loaded on top of the original jar. That means a JVM, mod-loader overhead, and inherited memory footprint.
This client ships a Rust engine instead — rendering, physics, networking, protocol, all rewritten from scratch. The payoff is lower memory use and faster cold start. The cost is everything has to be reimplemented one method at a time.
That's why the beta is closed and the feature list is short. It's also why each feature that ships is native, not emulated.
We're keeping this page honest. Here's what's broken right now.
Vanilla-physics-equivalent client movement still produces Simulation flags on strict Grim servers during sprint toggles, W-tap, and sword-block PvP. Root cause unidentified. If your server runs Grim with tight thresholds, expect false positives. Zombie/mob combat is unaffected.
There's no world generation, no integrated server, no local save. Multiplayer only. This is a scope decision, not a bug — the client is aimed at servers.
Some visuals are missing or placeholder: water flow direction, signs text rendering, banner patterns, piston animation, a few entity models. Functional but rough.
The roadmap section is aspirational. Today there are 14 working mods out of ~150 planned. We'll ship more over time, but don't install expecting Lunar/Badlion parity.
