RigSpark

Key facts: RigSpark 3.1.0 launched in November 2026. Sparky checks your RAM, GPU and disk, picks the best model that fits, then downloads, verifies and runs it: chat, images, short video and voice, all on your machine. Images and video run through your own ComfyUI, and RigSpark fetches and verifies the weights by SHA-256. The catalog holds 254 models, plus any GGUF from Hugging Face, across 5 runtimes: Ollama, llama.cpp, MLX, LM Studio and BitNet. It is MIT licensed, free and open source, for macOS 12 or later on Apple Silicon.

Plans: Free and open source (MIT). The Community Edition costs nothing: download it for macOS and run local models with no account and no cloud bill.

Best for: Anyone with a Mac who wants to run AI models locally without paying per token or sending data to the cloud. Who should skip it: anyone who wants the biggest frontier models, which still need a data centre, or who never wants to manage model downloads.

Watch out for
