It provides an OpenAI API-compatible interface and supports GGUF natively; pick LLM-Hub if local AI assistant for mobile phones via C++, supports multiple models. [shimmy](https://github.com/Michael-A-Kuykendall/shimmy) reports 5.8k GitHub stars, 559 forks, and 12 open issues, last pushed Aug 20, 2026. [LLM-Hub](https://llm-hub.app) has 561 stars, 116 forks, and 37 open issues, last pushed Aug 24, 2026. Figures are from public GitHub metadata via [shimmy's repository](https://github.com/Michael-A-Kuykendall/shimmy) and [LLM-Hub's repository](https://github.com/timmyy123/LLM-Hub). | | [shimmy](/tools/michael-a-kuykendall-shimmy.md) | [LLM-Hub](/tools/timmyy123-llm-hub.md) | | --- | --- | --- | | Tagline | ⚡ A Pure-Rust WebGPU Inference Engine, OpenAI-API Compatible and Native to GGUF | Local AI Assistant on your phone | | Stars | 5,808 | 561 | | Forks | 559 | 116 | | Open issues | 12 | 37 | | Language | Rust | C++ | | Adopt for | Shimmy is a Rust-based inference engine that excels in running AI models on various GPUs without the need for Python or llama.cpp dependencies.
