Openpets

OpenPets is a free desktop pet application. It installs animated companion characters on a computer, offers a gallery of pets to browse, and keeps its data local first. Its Plugin SDK, now in version 3, runs plugins in a sandbox so that behavior can be extended without giving them broad access. Since version 4, the pet includes an AI assistant that the user can type or speak to. It offers suggested prompts and a compact chat bar, and it can take real actions such as setting reminders and starting focus sessions instead of only answering questions. An official Anxiety Aid Tools plugin adds guided breathing patterns including Box and 4 7 8, a 5 4 3 2 1 grounding exercise, muscle relaxation, visualization, short meditations and ambient sounds with a sleep timer. A control center shows a dashboard of pet activity, lets the user map which animation plays for each reaction such as idle or working, and manages a library of installed companions. Optional local integrations connect pets to coding tools including Claude Code, OpenCode and Cursor, so a pet can react to what a coding agent is doing. It is aimed at developers and general desktop users who want a lightweight companion. Builds are available through a one command install, GitHub and the Arch User Repository. OpenPets is open source and the site states that it is free forever, with a price of zero in its structured data.
