Osaurus: Pricing, Features & Best Use Cases

Main limitation: It needs macOS 15.5 or later on Apple silicon, and the Windows version is not generally available yet.

What is Osaurus, and how does it work?

Osaurus is a macOS app (Apple silicon) that runs agents with memory, skills, code execution and web browsing. It can use local models or connect to providers such as OpenAI, Anthropic and Gemini with your own keys. Data is stored on the Mac, and a Privacy Filter redacts personal details before cloud requests. A paid Workspaces plan adds shared agents for teams.
