Harness

Harness

AI-driven user testing for iOS, macOS and web

Description

User testing before launch means recruiting people, slow and hard to cover every path. Harness uses an AI agent as a user, driving the iOS Simulator, Mac apps or web apps toward a plain-language goal and reporting friction.

It records every step with screenshots and flags confusing spots, requiring macOS 14+.
