iPhone Agent Harness

iPhone Agent Harness is a browser-based framework for running AI agent sessions on iPhone and iPad. Rather than installing a separate app, users open the site in Safari and work with a harness that coordinates models and tasks on the device. The project is hosted on GitHub, which signals an open, developer-oriented approach rather than a closed commercial product.

The interface centers on session management: users create new sessions, select a model, and archive conversations when finished. Beyond the core harness, the site links to a HarnessSkill community for sharing reusable skills and to a device flashing section, suggesting the project extends to customizing or provisioning hardware. These pieces point to an ecosystem around reusable automation components rather than a single-purpose tool.

Compatibility is a defining constraint. The harness only runs in Safari on an iPhone or iPad with iOS or iPadOS 27 or later; other browsers display a message directing users to the home page. This makes the site unsuitable for desktop users or older devices, and it means the audience is limited to those already on recent Apple mobile software.

For newcomers, the practical path is to open the site in Safari on a supported device, start a session, and pick a model before exploring the skill community. Those interested in the underlying code can visit the GitHub repository for details. Overall, it is a niche but focused environment for experimenting with on-device AI agents on Apple mo
