AgentiLoop

AgentiLoop Agent is an open-source native Mac app that controls other apps, writes code and builds Xcode projects from plain-English requests.

AgentiLoop makes Agent, a native macOS app that carries out tasks across a Mac from plain-English requests. It finds buttons, fields and menus by name through the Accessibility API, so it can click, type and scroll in any app, drive Safari and answer email. For developers it makes targeted string-replace edits with one-click rollback, and in Xcode it edits, builds, reads compiler errors, fixes them and commits. Users choose from 23 model providers with their own API keys, or run local models through Ollama, LM Studio or vLLM, and on-device Apple Intelligence handles triage, summaries and context compression without spending tokens. It supports MCP servers, up to six parallel sub-agents and custom agents written in Swift. The app needs macOS 14.6 or later, and a separate AgentiLoop CLI in Rust and Go brings the same coding loop to Mac, Windows and Linux terminals.
