llama.cpp Hub

Catapult is a launcher/manager for llama.cpp that brings together model exploration, downloading, and search, runtime preset management, server execution, and even a simple chat window all in one place.

The core point is that it exposes every option accepted by llama-server in the UI. It's designed so that frequently changing execution arguments or memory-related detailed settings can be adjusted directly in the UI without waiting.

The composition is as follows.

• GUI: The main interface, including model management and runtime/execution options
• TUI: Provides a separate terminal-based screen, allowing you to switch back and forth while viewing logs with the server running in the background
• Multi-platform distribution: Provided along with source code as Linux deb/rpm/AppImage, macOS, and Windows binaries
• Tech stack: The main engine is Tauri, and the license is Apache 2.0

The author states that this is currently a first release with polished features, and explained that it's actually a tool they use themselves. Community reaction has been largely positive, but there have also been practical usage questions about long-term maintainability, .ini preset loading, and comparisons with existing simpler script-based alternatives.
