HivemindOS is a local-first operating system for AI agents. It gives users a private control room for managing agents across laptops, desktops, servers, and cloud machines, all under one coordinated network. Instead of treating each agent as an isolated chat window or CLI session, HivemindOS lets agents share memory, context, tools, work queues, files, environment variables, and machine access. It is privacy-focused, crypto-native, and designed for people who want to operate full agent fleets while staying in control of their own infrastructure.
