Any recommendation of a 404 monitoring tool for Magento 2 that allows to create 301 redirects?

We’ve just migrated from M1 to M2 and it has been quite a messy migration with many URLs changing. In M1 we had a 404 manager extension which kept an check on 404s, counted how many instances of each and allowed us to ignore or create a redirect. I can find several options to achieve this in M1, but none at all for M2 for some reason.

Is anyone aware of a good tool we can use in our M2 store that will monitor 404s and allow us to manage them? Really I just need a list in a nice format as we will probably manually create redirects in nginx
