Ask HN: Best way to track mortgage rates

I am looking to find a convenient way to figure out general daily movement of daily rates.

What would be a reasonably good and convenient proxy rate that is trivially accessable and tracks 30 year mortgage rates reasonably well?

Is it accurate to say that the 30 year mortgage rate tracks the 10 year treasury yield? For example, if the 10 year yield is down by 5 basis points as compared to yesterday is it reasonable to say that 30 year mortgage rate should be down by 3-7 basis points as a result?

Is the relationship between 10 year treasury yield and 30 year mortgage rate directionally correct?

If there is a better proxy that is easily trackable and is readily available, I would love to hear about it.

I don't want to scrape lenders websites to get rates.
