Osaurus

Osaurus is a native macOS (Apple Silicon) application that runs open AI models locally on your Mac, keeping conversations, code, and files private because models and inference run on-device. It is designed as a local-first platform that remains fully functional offline and lets users add cloud models (ChatGPT, Claude, Gemini) only when a task demands external capabilities. The product emphasizes privacy (no telemetry, no training on your data), fast local inference on M-series chips, and is MIT‑licensed and free to use.

Osaurus supports building autonomous agents and automations that can read, write, and execute within your environment (drop a folder, assign jobs, voice control, folder watchers, browser plugins, parallel jobs). It also provides connectors to local model runtimes like Ollama, MLX, or LM Studio for one-click model additions.
