Shinkai

Shinkai is an open-source platform for building AI agents that run locally on a user's own computer rather than solely in the cloud. Its no-code builder lets people create specialized agents through a visual interface without programming experience, and because agent data and files stay on-device by default, the platform emphasizes privacy and control over where information is processed. Users can run models entirely locally, connect to cloud-based models for more capability, or mix both approaches depending on the task. The platform supports the Model Context Protocol (MCP), which makes Shinkai agents interoperable with tools like Claude and Cursor and lets agents access local files, browsers, and custom plugins. It also includes native support for cryptocurrency micropayments, letting agents transact using crypto, and an agent marketplace where users can share or monetize the agents they build. Shinkai runs as a desktop application on Mac, Windows, and Linux, with the underlying code published on GitHub under dcSpark. Shinkai is aimed at both developers who want programmable, portable agents and non-technical users who want AI automation without vendor lock-in. Its security has reportedly been audited by PeckShield and Halborn, though as with most crypto-adjacent tooling, users handling agent-based payments should independently verify security claims before relying on them for financial transactions.
