  1. caniuse

    Raw browser/feature support data from caniuse.com

    I have a fantasy where I scan some files, javascript, css, html, and it tells me which APIs or CSS selectors I'm using that might cause issues. It can cross-check with caniuse.com without actually having to simulate it in a browser. Somehow I think this has to exist, but I'm having trouble finding it.

  3. eslint-plugin-compat

    Check the browser compatibility of your code

    I've looked for this in the past. There's not much for this that is totally comprehensive. You might find success with eslint-plugin-compat which will error when using things that aren't supported in your browsers.
