Show HN: qckfx – Stop manually checking if your AI agent broke your iOS app
AI coding agents can build iOS UI, but they can't verify it. They can update a screen, but the UI might drift or break, and nobody catches it until a human checks.
qckfx gives your agent a baseline. Record a simulator session once. Every tap, scroll, and network response gets captured. On replay, each screen is compared against the original.
With our MCP, your agent triggers the tests and gets back visual diffs of exactly what changed. Updating the baselines is one click.
Under the hood:
- Full network replay (HTTP & WebSocket)
- Initial disk & keychain state captured during recording and restored on every run
- Precise scroll positioning (built from scratch; XCUITest only exposes this on macOS and iPad)
- No AI in the loop at runtime, fast execution
No SDK or code changes needed. Nothing to commit to git. Just download the app and go.
Everything runs locally. Your data stays on your machine.
