Agent! is a new open source macOS app that gives users full control over their Mac using 17 different AI providers, including Claude, GPT, Gemini, and Apple Intelligence. The app replaces paid tools like Claude Code and Cursor with a single native application that can write code, manage Xcode projects, automate Safari, and control any app via Accessibility.

Built for macOS 26.4+, Agent! features autonomous task loops that reason, execute, and self-correct without requiring manual configuration. The app includes Time Machine-style backups for every file change, privileged execution through a secure Launch Daemon, and dynamic tool discovery that automatically detects available applications. Users can run Agent! locally with Ollama or LM Studio, or use it free forever with on-device Apple Intelligence.

With no subscription fees, telemetry, or vendor lock-in, Agent! represents a significant shift in how AI can interact with desktop environments. The project's founder is currently battling cancer, making community support through stars and forks particularly meaningful. Available for download or build from source, Agent! demonstrates how open source alternatives can provide enterprise-grade AI capabilities while maintaining user privacy and control.
