What is Osaurus?

Osaurus is a native Swift app for running AI agents on your Mac. Open models run locally on Apple Silicon, so your conversations, files and memory never leave the machine. When a task needs a frontier model you can add ChatGPT, Claude or Gemini, and one shared memory carries across all of them.

It is a harness, not just a chat window. Drop in a folder and give it a job: Osaurus reads, writes and executes, with agent code running in an isolated sandbox. Build agents that run on their own - scheduled tasks, folder watchers, voice control, browser plugins, iMessage and WhatsApp agents - and set the app up by conversation with the built-in Orchestrator, which shows you exactly what will change before it changes it.

Osaurus ships its own model, Raptor 0.5: 6.3 GB, built for the 8GB and 16GB Macs most people own, and it stays loaded all day. It also speaks the OpenAI, Anthropic and Ollama APIs on one port, so existing SDKs and tools just work, and it connects Ollama, MLX or LM Studio models in one click.

Free, MIT licensed, no account, no telemetry. macOS 15.5 or later, Apple Silicon. Also available via Homebrew: brew install --cask osaurus.
