Getting Started

Installation & Setup

Download the verified installer for Windows, macOS, or Linux. Run the setup wizard and allow Stellar Client to detect your Minecraft .minecraft directory automatically.

Selecting Game Versions

Stellar natively supports Minecraft 1.8.9 (PvP optimized), 1.12.2, 1.16.5, 1.20, and 1.21. Choose your version from the launcher dropdown before launching.

Performance Engine

Dynamic Allocation Mode

Stellar actively manages Java virtual machine heap allocation and limits garbage collection pauses to sub-1ms cycles, preventing combat lag spikes.

Zero-Tick Render Pipeline

Bypasses standard client bottleneck loops to process entity and particle rendering asynchronously on modern multi-core CPUs.

Mods & Custom HUD

In-Game HUD Editor

Press Right-Shift in-game to open the visual layout canvas. Drag any module (CPS, Armor Status, Keystrokes, Ping, Potion Effects) and customize colors.

Mod Marketplace

Browse 120+ built-in approved mods with one-click toggles and zero server ban risks.

Troubleshooting & Support

Crash on Launch

Ensure your graphics drivers are up to date and Java 21/17 runtime is installed. If issues persist, verify game files in launcher settings.
