Own your AI. The native macOS harness for AI agents -- any model, persistent memory, autonomous execution, cryptographic identity. Built in Swift. Fully offline. Open source.
Osaurus is a native macOS application, written entirely in Swift for Apple Silicon, that acts as a local runtime harness for AI agents across multiple model providers including Claude via the Anthropic API, OpenAI, Ollama, and Apple Foundation Models. It exposes an MCP server so tools like Claude Desktop and Claude Code can connect to agents running locally on the user's machine. Core features include a three-layer memory system (identity, pinned facts, and per-session episodes with salience scoring and background consolidation), an isolated Linux VM sandbox powered by Apple's Containerization framework for executing shell, Python, and Node.js code without risk to the host Mac, cryptographic agent identity, self-scheduling, and per-agent encrypted databases. Tools and skills are selected automatically via RAG search rather than manual configuration. A notable detail: the VM bridges back to Osaurus over a vsock connection, keeping sandboxed agents connected to inference and secrets without exposing the host. The project targets privacy-focused developers and power users who want persistent, autonomous AI agents that run fully offline.
