Best alternatives to NobodyWho in 2026

Running an AI model usually means sending your data to someone else's server and paying per request. NobodyWho flips that: the model runs directly on the user's own phone, computer, or even smartwatch, with nothing leaving the device. NobodyWho is an open-source inference engine, built on llama.cpp, that runs large language models locally and efficiently on any device without cloud services, API keys, or internet connectivity. It supports text, vision, and speech models with GPU-accelerated inference (Metal, CUDA, Vulkan), and ships native SDKs for Swift, Kotlin, Flutter, React Native, Python, and Godot — making it usable across iOS, Android, Windows, Linux, and even game engines and smartwatches. It's free and open source under the EUPL 1.2 license, with around 1,100 GitHub stars.
