Open source agents that run 100% locally on your Mac
The native macOS harness for AI agents. Any model, persistent memory, autonomous execution, cryptographic identity. Built in Swift. Fully offline. Open source.
Hey Product Hunt, I'm Terence, founder of Osaurus. I spent 20 years shipping software at Netflix, Tesla, and Zillow before going all in on this.
Own your AI. Osaurus is an open source AI agent platform that runs on your Mac.
MIT licensed, native Swift for Apple Silicon. No account, no subscription, no Electron.
We started as Dinoki, a 5MB desktop dinosaur, and grew into a full agent platform through open source community feedback. Now at 7K+ GitHub stars and 175K+ downloads — all by word of mouth.
The problem: most AI assistants run on someone else's server.
Your files, memory, and context leave your machine every time you use them, usually behind a monthly subscription.
Osaurus keeps all of it on your Mac.
What that means in practice:
Agents read your Calendar, look up Contacts, send iMessages, and work with your real files
An isolated sandbox writes and runs code, producing real files on your desktop: images, PDFs, presentations
Every action goes through an approval gate. You see what the agent wants to do before it does it
Local models run fully offline. We built our own Swift MLX runtime, no Python underneath
Want a frontier model? Bring your own key (OpenAI, Anthropic, Gemini) or use pay-as-you-go Osaurus Cloud. Either way, your memory and context stay local
It's free and always will be.
16GB of RAM gets you started with local models, 24GB recommended.
Try it at osaurus.ai. Download takes seconds, no account needed.
I'll be here all day answering questions. My favorite Osaurus hack is to set up Agent DB and self-scheduling to create a personal dashboard!
