How to know if an extension is jQuery free

How to know if an extension is jQuery free

I'm helping a client build a Magento 2 website.

We have strict requirements for page speed.

We may even use the Hyva theme because it looks very good speed-wise.

We can't use jQuery, it would make the website too slow.

Is there a way to know if Amasty's extensions use jQuery prior to purchase?

Thanks
