FutureOS is an open-source AI agent that follows you across every surface you work on: a Rust core driving a terminal UI, native desktop app, mobile apps, CLI, and IM bots — one backend, one memory, one set of skills. 3,800+ models from 140+ providers built in, or bring your own endpoint. Every tool call gated by your approval, with sandbox tiers underneath. A built-in loop control plane keeps 24h+ long tasks durable, resumable, and verified. Local-first. Open source (MIT + Apache-2.0).
