osaurus

Why we included this project

Osaurus moves the whole agent runtime onto your Mac, so the models, memory, and execution stay on-device rather than running in a hosted service. It's a native Swift app for Apple Silicon that runs open models fully offline through MLX and Apple's foundation models, while still letting you attach hosted models like ChatGPT, Claude, or Gemini for individual tasks. The center of the experience is the agent loop: you pick a working folder, toggle a sandboxed shell, and the model writes a todo list, works through it, and closes with a verified summary in the same chat window. Beneath that sit layered persistent memory, a tool and plugin system, MCP support, per-agent browser automation, and a cryptographic identity chain, so autonomous agents can act on your machine without your data leaving it. If you want a self-contained, offline alternative to hosted agent platforms, this is a polished native client rather than a server stack you have to assemble and maintain.
