About Osaurus
FreeAdvancedNo APIDesktop · CLI
Osaurus is a native macOS application that lets you run AI models entirely on your Apple Silicon Mac, ensuring your data never leaves your machine. It supports local open models like Llama and Mistral, and can optionally connect to cloud services like ChatGPT, Claude, or Gemini when needed, with a shared memory across all models. Built for developers and power users, Osaurus enables you to create autonomous agents that write code, use your tools, and evolve over time. It offers voice control, folder watchers, parallel jobs, and a plugin system for browser and file integration. The app is fully offline by design—Wi-Fi off, it still works—and your data stays on your Mac unless you explicitly allow it to leave. Osaurus is open source (MIT license) and free forever. It requires macOS 15.5+ and Apple Silicon. The project has garnered over 162,000 downloads and 6,600 GitHub stars. Recent launches include AppleScript-8B and AppleScript-16B, open models that turn plain-English requests into macOS automation on-device. Osaurus positions itself as a privacy-first alternative to cloud-dependent AI tools, giving you full control over your AI stack.
Behind the Verdict
Osaurus nails the privacy-first local AI vision for macOS. It's a native app that runs models like Llama and Mistral on your Apple Silicon Mac, with zero data leaving unless you choose. The persistent memory across local and cloud models is a smart touch—you can use ChatGPT for complex tasks but keep sensitive work local. We'd reach for this when building autonomous agents that need to write code, run tools, or automate folder workflows. The recent launch of AppleScript-8B and AppleScript-16B models is a game-changer for macOS automation, turning plain-English requests into on-device scripting. Where it bites: macOS 15.5+ and Apple Silicon only—Intel Macs and other platforms are out. It's also advanced; you'll need comfort with the terminal and local model management. Compared to LM Studio, which focuses on chat and model browsing, Osaurus excels at agent creation and tool integration. If you're a Windows or Linux user, look elsewhere. For macOS developers who want to own their AI, Osaurus is free and compelling.

Limitations
- Osaurus currently requires macOS 15.5+ and Apple Silicon; Intel Macs are not supported.
- The free tier relies on local models which may be less capable than large cloud models for complex tasks.
- There are no documented rate limits or context window restrictions, but local model performance depends on your Mac's RAM and GPU.
