Phone Harness
Phone Harness is an open-source framework that lets AI agents operate real iPhone and Android devices by tapping, typing, and scrolling through native UIs, with no jailbreak, API, or app installation required. The system reads screens via vision OCR or the device's accessibility tree, and connects to iPhones through mirroring and Android devices over ADB. A hosted cloud service provides rented, persistent phones with real numbers for SMS and 2FA, billed per minute.

Problem
AI agents often lack the ability to interact with real mobile devices and native apps, limiting their usefulness for tasks that require actual phone operation. Existing solutions may require jailbreaks, custom APIs, or app installations, which are complex, fragile, or unavailable for many use cases.
Solution
Phone Harness provides an open-source framework that enables AI agents to control iPhones and Android devices by interacting with the native user interface—tapping, typing, and scrolling just like a human. The system reads screen content via vision OCR or the device's accessibility tree, and connects to iPhones through mirroring and Android devices via ADB, requiring no jailbreak, API, or additional app installation. A companion cloud service offers hosted, real hardware phones that can be rented by the minute, providing persistent state, real phone numbers for SMS and 2FA, and the ability to scale from one to hundreds of devices. The framework is MIT-licensed and supports bring-your-own-device workflows, allowing agents to operate a user's own phone from anywhere.
Target Audience
Primary users are AI developers and automation engineers who need their agents to perform real-world tasks on mobile devices, including testing, workflow automation, and app interaction scenarios.
