Show HN: Stealth Benchmark test if AI coding interview tools can be detected
Stealth Benchmark is an open-source tool designed to simulate detection methods used by AI coding interview platforms. It allows users to test their setup for potential red flags before taking a real coding interview. The tool checks for various browser and system events that interview platforms might monitor.
- ▪Stealth Benchmark detects events such as window focus loss, tab switching, and DevTools opening.
- ▪It categorizes risks as high, medium, or low based on the likelihood of being flagged by interview platforms.
- ▪The tool cannot detect running processes or specific overlay windows due to browser limitations.
- ▪Users can run the tool by simply opening the index.html file in a browser with no dependencies required.
- ▪The project is open for contributions and follows the MIT license.
