Ask HN: Tool that can check my front-end files for browser coverage

I'm searching for a tool that can help me analyse the code in my HTML, CSS and JS files and inform me which browser isn't compatible with the API or method I've implemented in them, currently i end up testing the website on all browsers to check for compatibility issues and once i find them i verify on caniuse.com and check SO for alternatives. I recently found out doiuse.herokuapp.com and check my CSS files there. Is there any other tool that can help me?
