Is there any possibility of using es6 promises today on frontend side without require js?

In the latest Chrome/Firefox/Safari/Edge, Promises are already supported natively.

If you do want to use other ES6 features, and especially on older browsers, you could keep adding polyfills but at that point it might be easier and more future-oriented to just use Babel and its env preset.
