Agent Infrastructure · Head-to-head
cua vs osaurus
cua and osaurus are both agent infrastructure. cua is Open-source infrastructure for Computer-Use Agents. Sandboxes, SDKs, and benchmarks to train and evaluate AI agents that can control full desktops (macOS, Linux, Windows), while osaurus is own your AI. The native macOS harness for AI agents -- any model, persistent memory, autonomous execution, cryptographic identity. Built in Swift. Fully offline. Open source. Here's an independent, side-by-side look at how they compare — and which fits.
