A lightweight, extensible desktop companion engineered in Rust. Interacts with open windows, reacts to your focus, and maintains zero cloud telemetry.
OpenPet splits functionality across dedicated lightweight Rust crates to maintain predictable memory usage:
Unlike bloated Electron companions consuming 300+ MB of RAM, OpenPet uses native WGPU/DirectX surface layers, dropping to 0% CPU consumption when idle.
AGPL-3.0 licensed open-source companion platform. Clone and build cleanly with cargo on Windows 11 in seconds.
