Osaurus

Osaurus is an AI agent harness for macOS that runs local or frontier models with persistent memory and autonomous execution.

Osaurus is a native macOS application that lets you run powerful AI agents on your own hardware. It supports local open models via an inference engine built for Apple Silicon, as well as cloud models like OpenAI, Anthropic, and Google Gemini using your own API keys. The software features persistent memory, autonomous execution, cryptographic identity, and isolated sandboxes for running code. Users can import markdown skills, extend tools using Model Context Protocol, and automate tasks on a schedule. It is built for individuals and teams who want to own their AI workflows without sending data to third-party servers. Workspaces allows teams to share agents and run workflows over an encrypted network.
