Valuation websites

Hi there,
I am just wondering if anyone knows of any reliable or reputable websites that provides valuation for stocks?

I am using simplywall.st but I feel that it would be more reliable to cross-reference between a few sources. I am not sure how simplywall.st churns out its values, but I feel that they tend to value more leniently.

Any help would be greatly appreciated.
